Re: NV4500 swap is underway
 

Wow, a S6-650 behind a 6.2L must be like driving a race car engine backed by a dump truck transmission :lol:

Glad you like yours….you could have the ZF S6-650 in my 2001 2500HD. I hate the damn thing. Worst shifting manual trans I’ve ever owned with an even worse shift pattern. I’ve own that truck since new and 13 years later it has finally started to loosen up where it isn’t quite as notchy as it was up to this point (It just turned 59,000 miles last week) but I still hate it. The clutch pedal geometry on the GMT900 trucks is also quite funky. There is no slip to it, it works like an on/off switch where it is almost impossible to launch the truck smoothly. Between the clutch operation and the awkward shifting ZF 6 speed is why it has only racked up 59K in 13 years. I don’t like to drive it much.

I still prefer a NV4500 over the ZF any day, but there is no doubt about it the ZF is a much stronger transmission by a long shot.

Re: NV4500 swap is underway
 

Like I said before and someone else mentioned it before, my S6 650 (and his) shift really smooth, so you must have gotten a bad one. And I have to admit that my clutch linkage and all that is totally different anyways since I jused the duramax hydraulics with the OEM 78 clutch pedal with a home turned and welded mount. so my clutch pedal has about half the throw of the stock one. Takes a little to get used to, but makes for really fast shifts. And together with the 6.2 L92, it makes for a fun and fast combination. The ZF in my truck the way it is set up actually has relatively short throws for a truck tranny and also I think it shifts really nice. You really must have gotten a bad example.

I even think I have an on bord video from a stand still shifting through the gears..that shows how nice it does shift...

Re: NV4500 swap is underway
 

Glad you are enjoying it. There is no doubt in my mind that transmission will probably last forever. I don’t buy into that I got a bad ZF 6 speed as I have driven several other ZF 6 speeds in GM and Ford Stupid Duties and they shift equally sucktastic, but that is just my opinion. I happened to love the way the NV5600 shift gates and pattern is laid out but there are people that hate that trans and prefer the ZF 6 speed. It’s all in what you like. I still like the NV4500 the best.

Re: NV4500 swap is underway
 

So it’s been almost 4 years and 10 to 15,000 miles since the NV4500 swap and last March coming back from Death Valley the NV4500 really started screaming in 5th gear. With that I knew it was time for a 5th gear cog and fresh mainshaft. Not wanting to cut another mainshaft to make the Advance Adapters kit work I started getting serious about finding a round pattern 205. Once again, birddog Mosesburb found me one with member Ryanroo so coming back from the Overland Expo in Flagstaff last May I stopped by Ryan’s place and picked it up (Mosesburb is like a bird dog….tell him what you want and he can sniff it out, anywhere anytime. He found my brand new in the box front Dana 60 and a few Warn winch bumpers for me).

So the big mystery here is why did the trans defecate 5th gear in the first place?? Well, at first I really wanted to blame the Advance Adapters kit just because I typically really hate aftermarket stuff but once my trans rebuilding friend took it apart, the AA collar that holds 5th gear was tight to my surprise. I figured the AA collar came loose and allowed 5th gear to walk around and knurled the mainshaft. The mainshaft was indeed slightly knurled and the gear did rock a bit but the collar was indeed holding it tight. With that, maybe the naysayers are right about towing in 5th gear eat up NV4500’s. I dunno, I know a few guys that tow like crazy in 5th gear and have never had a problem with them. I also don’t tow but the truck does weight 8,000 lbs. Maybe I overheated it in Death Valley and hauling balls down the mountainious Hwy 160 from AZ to I-25 in Trinidad, CO http://coloradok5.com/forums/images/smilies/dunno.gif

Not sure, but this time the 205 will directly mounted to the trans with no adapters and coolers are being added to the trans just for safe measure then we’ll see how it does. If this things craps again, next go around will be something different like an Allison. That would be a tough pill for me to swallow because automatics are against my religion.

Bought this gem from Ryanroo. A round pattern 205 :smoke:
http://farm6.staticflickr.com/5526/1...891311b6_b.jpg

I didn’t get around to ripping into the round 205 until December 2013. It came to me with a slip yoke rear but I used the rear section from another 205 I had laying around with a 1350 fixed yoke. I also traded did some trading with ORD for the long 32 spline input for a short 32 spline input. This picture is just after I gutted it in preparation for sand blasting. The internals were in great shape, almost like new. I only had to replace two bearings in the whole thing.
http://farm4.staticflickr.com/3725/1...c5d3efe1_c.jpg

The rear transfercase section actually came out of the 205 that was in my dad’s ’78 K20 wrecker. No wonder the speedo hasn’t worked in that truck for many years! Look at that speedo cog! The good news is you can still buy new ones from GM.
http://farm4.staticflickr.com/3686/1...c5bbabbe_c.jpg

I also got a new speedo adapter for it as well. There is a seal inside the adapter that isn’t replaceable but you can get new adapters from GM also. The new adapter is not pictured here though.
http://farm4.staticflickr.com/3676/1...f45353ce_c.jpg

With getting away from the AA kit also meant I had to find an OEM rear trans cover and modify it to clear the shift rail and idler nut. Argonaut and I were going through the mods at the same time and both of us did pretty much the same procedure to make the clearance holes.
http://farm4.staticflickr.com/3800/1...3431a704_c.jpg

My ain’t that purdy!
http://farm4.staticflickr.com/3714/1...b3a52a5f_c.jpg

I used a wood spade to make the hole :lol:. Hey, it worked!

After making an access hole for the range shifter rail and idler shaft nut clearance
http://farm8.staticflickr.com/7362/1...a9f98e3d_c.jpg

As Argonaut pointed it out the trans cover needs to be clearance to allow the 4 NP205 front seal retainer bolts to pass through. This was before I made the mod
http://farm6.staticflickr.com/5507/1...9cd07552_c.jpg

It doesn’t take much elbow grease with a rattail file to make a pass through for the tcase front seal retainer bolts. A bit of flat filing on the seal retainer itself was also required as it appeared to be too thick to seat into the transmission cover properly.
http://farm6.staticflickr.com/5476/1...ee52fae3_c.jpg

Here tis right before I stabbed it in the truck.
http://farm8.staticflickr.com/7376/1...cb33a7d0_c.jpg

Here is the trans all sinched down. One thing new is the Energy Suspension trans mount. The old AA kit trans cover bolted directly to the homemade square stock bracket.
http://farm8.staticflickr.com/7345/1...39a0391b_c.jpg

So that is where I am at as of right now while I wait on a few parts. The drive shafts are in town being reworked as the rear is being changed to a 1350 U-joint for the tcase end and I am using a flange mount front shaft this time instead of the old yoke style mount that is a MOFO to install due to only being able to turn the bolts ¼ turn a time. The new front shaft needed to be lengthened and of course the CV needed the full-on replacement. The shafts should be done Monday and the trans coolers should be here Tuesday. That’s it for now!

Here is the old deal buttoned down to a crate ready for a new home.

Re: NV4500 swap is underway
 

I swear, you have 205's springing up there like garden Gnomes. Good work as always.

Re: NV4500 swap is underway
 

I have a 205 population issue here to. Even though Larry decided to try and help it didnt matter. only a few months later another wayward gearcase found a home under my workbench.

Larry, you may know this already and not care, but an OEM trans W style trans cross member will bolt right up to the NV4500 mount without the need for the double stack of bushings.

As always your work is fantastic and very clean. looks great

Re: NV4500 swap is underway
 

Hehe, seems that way :lol: Can't have too many spare parts though.

I think all 4x4 gear heads have at least one or two tcases laying around. Mosesburb has a 205 or two laying under his bench too. Thanks for the kind words dude.

Ah...yes, you mean this crossmember like what is in my Polar Bear Burb below? Ya, I know it that xmember works great with a NV4500 but then period correct double xmember and big skid plate wouldn’t fit plus both xmembers would have to be moved back a few inches which would be an issue on a short bed. I also didn’t want to drill more holes in the already overtaxed 1/2 ton frame. For those reasons we made the cantilever bracket for the mount to mount in order to keep the stock xmembers in their original locations.
http://farm9.staticflickr.com/8079/8...c8f6699f_c.jpg



This is an OLD picture but I like this xmember and skid plate combo better than W xmember in the Burb. The W xmember sure makes the NV4500 an easy swap though!
http://farm6.staticflickr.com/5170/5...067286ee_z.jpg

Re: NV4500 swap is underway
 

Hmmn. that was one i hadn't seen before. i didnt realize the late 80s/early 90s trucks had different crossmembers.

this is the one i was thinking of. this is your case in its original home.

http://i94.photobucket.com/albums/l8...15/m715166.jpg

I understand about not wanting to change the current stuff. if it works why mess with it. i figured you knew about the other options but ya never know...

Re: NV4500 swap is underway
 

The xmember in the Polar Bear Burb is the original SM465/241 piece. This was the only “W” type I knew about.

Hmmm, well heck! I don’t recall seeing the one you posted before. It looks like it might work just as well, if not even better, if it mounts in the same spot as mine. Looks like the current skid plate would still work and nice clearance for exhaust too. I’ll keep my eyes open for one like that if I ever need to change it for some reason. Thanks for the heads up!

Re: NV4500 swap is underway
 

Perhaps the reason for the 5th gear failure comes from high frequency vibrations present in the absence of the stock damper.

In my research I seemed to find that the Dodge units without dampers had more fifth gear failures than the Chevy units which use them. This may have been coincidental, but the engineers decided to use the dampers for a reason and so it was a one of the reasons that I decided to retain the stock damper and adapter just like Larry is showing here.

Larry are you at all concerned that the NP205 weighs almost twice as much as the 208 or 241 that was intended to hang off of that adapter?

Re: NV4500 swap is underway
 

Out of my own experience with an aluminum tail housing braking off dumping the t-case on the interstate, I can just advice everyone to run a second crossmember, second tranny mount and an adapter like I have used on my truck. Works perfect and gives you the extra insurence in case something does let go, that the t-case will stay unter the truck.

here are the pics...

Re: NV4500 swap is underway
 

I often wonder about the damper too. GM applications didn’t use dampers behind gas engines, only 6.5L diesels to dampen the pulses of the rattley diesel. Sometimes I also wonder if the way I lug the truck does more damage than just conserving fuel. The 8.1L has plenty of torque where I am often already in 5th before going 40 – 45 MPH.

No, I am not worried about the weight of the 205 on the aluminum adapter/rear trans cover at all but maybe I should be?? To me, the NV4500 aluminum adapter even looks sturdier than the old school 465/205 adapters that were known for cracking. Now with that said, had I used a 205/203 doubler like others have done I definitely would have gone with a cast iron adapter. Seems all the cast iron adapters are for the Dodge version of the NV4500 instead of GM. Maybe I am wrong or just didn’t look hard enough. What are you planning to do with yours? I certainly do not recommend using the 205 side bracket to bolt it to the frame!

Re: NV4500 swap is underway
 

ive had my 205 hung off the back of the GM 4500 tail housing in my jeep for the last 4-5 years. no issues at all. granted it doesn't see a lot of miles, but i have beat and bounced it pretty hard on a few occasions. i even have the AA spacer to amplify the situation. cast aluminum doesnt stretch, or bounce much, so unless the mating of the two is loose, it would have little room for movement that would lead to cracks. i also have a big block in mine and drive in 5th almost all the time on the road. my 4500 came behind a 350 originally and has no damper. it had 125k on it when i pulled it and all i did was an inspection and stuck it back together. anyhow, i haven't yet had any 5th gear issues. ill hope that remains the case.

Re: NV4500 swap is underway
 

Larry, that 205 looks pretty dang nice. Most of the 5th gear issues we see are on pre 98 dodge NV4500's that aren't upgraded at all, and on the 98 later ones, people having double or triple the power and driving like sports cars. :lol: I agree, I believe lugging is what takes most of them out. We've had a couple with upgraded nuts and main shafts still have issues. They were stock VP trucks. Another new nut and some performance upgrades and they have been fine. They tow in 5th all the time and it's been over 2 years now. The new 5th gear fix is the best way to fix it but kind of costly. My brother put one in his 92 F-350 after the nut backed off it on the way to Ca a while back. I was surprised it came off but that truck was used as a pulling truck the whole summer before. :lol:

On the weight hanging off the aluminum tail housings, yeah, we've seen a couple of first gen NV4500 swaps that had an early failure from the tail housing being cracked and the trans gear lube leaking out and the trans being ran out of oil until it's dead. We switch over to a cast tail housing on all of them we do just for peace of mind. That second mount is a good idea too.

Re: NV4500 swap is underway
 

My plan all along has been to add a simple steel brace that sits above the tail housing and bolts to the upper two locations on the transmission and the upper three locations on the transfer case. It's a little hard to explain and I haven't yet sketched up a design. Just a couple ideas floating in mind. The point is that the top of the tail housing is in tension from the moment about the mounting points caused by the gravity force on the transfer case. My steel brace would allow the tension forces to be transmitted through it, in addition to the aluminum housing, directly from the t-case to the back of the trans. Unfortunately this does nothing to absorb the shear forces, but perhaps that could be mitigated if the brace also tied down to the tail housing mount locations. I'll need to think about it a little more before I start fabricating.

Or maybe the additional rear mount would be easier :)

Re: NV4500 swap is underway
 

My thoughts when i built the jeep, were to take off from the rear output housing mounting bolts. then i could hang the case from the top and it wouldnt be as much of a pain to drop it. i still wouldnt mind doing it, as it sits now the belly pan also supports the trans and transfer. it makes it a bit of a chore to pull the belly pan. i would much rather have the gearboxes hung from the top so the skidplate can be removed without as much hassle.

i wasn't terribly worried about it causing fatigue issues so i never pursued the second mount and i had some clearance issues for fabricating the top mount which have since been relieved by some roll cage tubing.

Re: NV4500 swap is underway
 

I don't know all the ins and outs of NV4500/205 setups since I don't have that in my truck BUT, I thought I should post this just in case you guys hadn't seen it: http://diy4x.com/cart/index.php?rout...product_id=202 . Maybe it helps, maybe it doesn't. Great thread though. Thanks for all of the info!

Re: NV4500 swap is underway
 

Well, I am not going to worry about an added support for the 205. There are lots of people running this combo just like I have it with great success. Maybe it if was a full on rock crawler or something crazy it would be more important. Hell, I’ve got a nice big skid plate to catch it if it falls off! :lol:

Alas she’s all bolted together again! All I have left is to install are the new shift knobs coming from JB Fabrication which should be here Friday. One of the ORD shift knobs broke when I tightened it too tight, glad it broke too as the JB knobs have the shifter map engraved in them. :lol: I haven’t had a chance to go for a test drive yet as the batteries were dead (poor truck hasn’t left the house since last June)....maybe Friday I'll be able to take it for a spin.

Picked up $475 worth of driveshaft’s Monday. The rear needed a new stub and slip yoke to accommodate the change to the larger 1350 u-joint at the tcase. I’ve had a 1350 at the rear axle for quite a while but the tcase end was really small, like a 1210 or something. The front shaft needed the works…CV rebuild, new joints, the stub and yoke were loose so they got replaced and it needed to be lengthened almost 2”. All the U-joints are the Super Brute solid core cross shafts.
http://farm4.staticflickr.com/3818/1...73d44e86_c.jpg

Beefy. It’s an optical illusion where the ebrake cable looks like it is near the yoke when it is actually a few inches away from it.
http://farm8.staticflickr.com/7410/1...fd470f5d_c.jpg

I spent a lot more time this go around fine tuning the ORD twin stick adjustment. I really like the way it shifts now. Having front wheel drive seems really weird to shift only that stick. BTW….to run only in front wheel drive the rear shifter must be left in neutral, which is nice so you don’t end up running the front and rear in two different range speeds.
http://farm4.staticflickr.com/3826/1...7de4d4d0_c.jpg

The trans coolers are HUGE! The coolers also add 2 quarts of capacity. Either they are going to help keep the fluid cooler or help keep it really hot from the heat of the exhaust :lol: Time will tell! The picture also makes it look like the front shaft is uncomfortably close to the trans cooler but there is plenty of room. The Dana 60 will have to crash through the 8.1L oil pan before the shaft hits the cooler.

Now that all this is done I’ve still got a ton of work to do to it before the next big desert trip coming up in May. The rear winch needs work (again) because it stopped working (again). This damn Milemarker winch is broke more than it actually works. Junk!

Then I need to get it up to Denver to spend a week with Phoenix as they are going to remodel the kitchen area to the latest and greatest stove/sink combo instead of the old fashion rattle trap camp stove that is in it now. It is also getting fitted with 100W solar power.

Lastly, I may still have an issue with the rear axle to figure out. Last spring on the Death Valley trip it puked out over a quart of 80W-90. When I got home I changed the rear cover to add capacity then filled it with Synthetic thinking it just overheated. A couple months later I drove it to Arizona for the Overland Expo and the sumbish puked out another quart of oil out the vent on that trip. Talk about a friggen mess all over the rear of the truck and camper when it decides to have its gear oil orgasm. I’ve since replaced the vent hose and installed a new vent so the trip to Denver should be a good test for that. I just don’t know what would cause this thing to start puking out oil out of the blue. There is zero noise coming from the axle that would point towards any bearing issues. :crazy:

Re: NV4500 swap is underway
 

I am envious of that awesome setup, DirtyLarry!

Re: NV4500 swap is underway
 

Me too!

Excellent work :metal:

Re: NV4500 swap is underway
 

Arrrrrrrrrgh! I'm jealous that I'm lagging so far behind you!

How are your u joint angles on the rear with that driveshaft? I was assuming that I might need to rotate my rear axle and go with a double card an joint at the TC due to the added length over my SM465/NP205 combo.

Re: NV4500 swap is underway
 

Well, get to work man! :lol:

Maybe my 205 will break off of the NV4500 rear cover by the time you get yours together that way you can confirm a brace is needed ;)

The rear u-joint working angle is almost too flat. The handy dandy phone app angle finder says there is a 2.6 degree working angle at the rear joint. I'm not using any shims...just the ORD flip kit and a lot of weight in the bed :lol:

Re: NV4500 swap is underway
 

Interesting. I assume that you don't have complimentary angles on your TC output and your pinion... and as such I'm surprised you don't have any vibration issues. Or do you?

Re: NV4500 swap is underway
 

And yeah, I'll definitely let you be the guinea pig! ;)

Re: NV4500 swap is underway
 

Rear axle u-joint cap: 10.2 degrees
Driveshaft: 12.8 degrees
TC u-joint cap: 4.6 degrees

The angles are not ideal but there is no driveline vibration between 0 – 93 MPH. The truck is amazingly smooth rolling down the highway even with the 35” tires.

The angles change once the fuel tanks, water tanks, fridge, etc. is full/loaded. Hmmm, I ought to check that someday once the camper is loaded to see how much they actually do change

Re: NV4500 swap is underway
 

Larry, I was thinking of just making some braces similar to what a 208 has to help support it and see if that works. Maybe that would be an option for you too.

Re: NV4500 swap is underway
 

What does the NP208 brace look like? Anyone have a pic?

Re: NV4500 swap is underway
 

It looks like the rod below where it runs from the bolt holes in the side of the tcase to the bellhousing. I’ve never actually seen these rods used on anything other than automatic transmissions and even at that…not all had them. Certainly not a bad idea and definitely a better idea than having the tcase mounted on its own mount. The tcase needs to rotate with the torque roll of the engine and transmission. When the tcase is cinched down you run more of risk of breaking an adapter by drivetrain twist than I do by not running anything at all. GM broke a lot of tcase adapters on 69-72 trucks because of the frame adapter that bolted to the side of the 205 for this exact reason. They did away with that bracket in 1972 because if it. That is directly from an old work colleague that was a GMC truck engineer from the late 60’s through the 90’s.

http://www.pirate4x4.com/forum/attac...upport-rod.jpg

Re: NV4500 swap is underway
 

Larry, my thoughts are the same as yours on that. I almost put the GM tcase bracket back on when I did the 89 yellow suburban, but changed my mind due to thinking the trans tail housing would just get broken because something would definitely have to give. Now that we are talking about it, I've never seen a 1st gen dodge with an auto and NP205 break the trans tail housing. Maybe their housing is just engineered to take it. IDK They do seem to live just fine though.

Re: NV4500 swap is underway
 

I dunno, but I can tell you that I am sick of hearing about a brace/mount for the 205. :lol: That topic has been beat to death already in this thread several pages back. I heard the same thing when I first did the NV4500 swap in 2010 that I needed a brace. The truck does more long distance highway trips and real world off-roading that most on this board will ever see. It’s been to the Mohave Rd & Death Valley in California, 2 trips to Flagstaff and several trips to the Utah back country not to mention the local mountain trips just in the last 3 years. The old dog sees a lot of dirt and 4x4 action. It never leaves the house unless it is really going somewhere. Not a grocery getter rig that is for sure. No problems yet and I sure hope it stays that way. I was looking at the odometer today and it has 14,823 miles since the NV4500 swap in late 2010. All of those miles were outdoor adventure miles. If I had an hour meter I would venture to say it has many more off-road hours than on-highway hours by a long shot.

Well, the JB Custom Fab twin stick shift knobs arrived today! I gave it a 20 mile test drive this afternoon and all is well. No leaks, no noises but there a slight vibration in 4wd and fwd that I didn’t have before. Gonna have to look into that.

I dig these new knobs! I am really happy with the silky smooth shift action of the 205 now as well! It is hard to believe it is a 205 as usually you almost need to put your feet on the dash to shift the damn things :lol:

Re: NV4500 swap is underway
 

Those are some nice knobs for sure! For whatever reason, most of the old first gen dodges I've been around, you have to play a freakin game to get the tcase to go in and out of 4x4 just like you're saying. That's awesome it shifts really smooth.

Re: NV4500 swap is underway
 

I am in the middle of my nv4500 swap with advanced adapters parts . just wondering where you located your pilot bushing. AA suggested leaving the bushing 3/16 out of the end of the crankshaft . I always put them in flush, any comment appreciated ! thanks

Re: NV4500 swap is underway
 

I am running the stock 8.1L pilot bushing, which is considerably different than the typical small block and older big block bushings that were used forever. However, on my 89 Suburban with a TBI 5.7L I just used the stock pilot bushing. The NV4500 swap on that rig is on page 5.

Re: NV4500 swap is underway
 

A lot of good pics/info in this thread. I have the trans, and the round pattern 205 that (if I ever just break down and start doing it) will be going into my truck. I need to order the short input from ORD for the transfer case, and I can start to get moving. I'll have to use this thread as a reference when I finally get my ass in gear.

Re: NV4500 swap is underway
 

Figured out the source of the noise and vibration in 4wd and fwd. I forgot to clearance the CV to prevent rubbing:dohh:.

I intended to do this before the front shaft was rebuilt and balanced but I forgot. Dang it!

Re: NV4500 swap is underway
 

Larry-
The GM cast iron adapters are indeed out there.
Here is a pic of the factory damper you were talking about.
Other pic is of a strut rod I made up for the 4 months I had this combo before doubler install.
I took a piece of round that fit tightly over a factory strut rod ;cut the rod slipped it inside bolted it on to orient then tacked it; then took it off to weld it and paint.
Simple enough to fab if you wanted to.
Strut rod came off 78' NP203.

Re: NV4500 swap is underway
 

Yeah, the cast iron adapters are out there all day long for the Dodge version of the NV4500 but I haven’t seen any for GM. It is my understanding the length is different between the GM and Dodge versions. If you have a cast iron GM version where did it come from? You know, I might need one cuz the aluminum adapter is going to break and my 205 is going to fall off according to the internet :rolleyes:

In hindsight I wish I would have had the 6.5L damper installed while the transmission was apart. I didn’t even think about that thing. Too late now, the truck is all back together. Guess it will have to wait until I have to replace the adapter when it breaks ;)

Re: NV4500 swap is underway
 

Oh yeah. It'll probably break going over the first speed bump at the mall. Better prepare yourself! :)

I was thinking of finding the hens tooth GM NV4500 cast iron adapter and bolting it to my spare tire carrier and just leaving the spare tire at home. Sounds like I’ll need the spare cast adapter before I will ever need the spare tire :lol:

Larry-I got mine from risingvoffroad (Ryan) 217-304-4663- Moonshinemafiamotorsports I got it for $150.00 plus shipping just last year.
If you mount it where the spare tire goes you may need to beef up the rear suspension! :lol:
