Wow ...what a cutie in the last pic!!!!

[JIMs70GMC]

Looks good!

[68C15]

that looks sweeeet! the truck/trans looks good too.
I like your tranny jack. do you plan to bend the shift lever to clear the seat?

[chevyfarmer]

super nice set up
is the tranny new? where did you get it?

[BobbyK]

Well the pic's are GREAT,but you have to go into some more detail man!
This is a potential project for me so info like the 205 shifter,what clearance issue's did you have with it.

How much longer is it compared to the TH350/NP205 combo.

Can you get some closer shots of the NV4500/NP205 adapter.

Why did you shim down the trans crossmember?Could the mount inbetween the NV4500 and the trans crossmember have been made thinner so the trans crossmember didn't have to be lowered?

Stuff like that.

Excellant pic's though!!!!

Looks good!!

[ryanroo]

Well thansk for the compliments.

i don't think i will bend the shifter, because i plan on bucket seats in the future($$$) and i am also planning on installing a short shift kit, which will raise the entire shifter enough to clear the bench as it just barely rubs.

i got the tranny from a member who bought it all new from Advanced adapters and had the 205 rebuilt.

I can go into better detail and post any pictures that you all want, but i am headed to wyoming this evening to visit my new school, so i will have to do it later this week.

I know the crossmember was moved right at 2 inches back but mine was a 4 speed priginally, i don't think that it is any different than a th350, and imnot sure what the deal is with the spacers, the t-case was going to hit the cab and it sets at what lookes like the same angle as it was with the stock set up, with the 1.5 inch spacers. i think i can machine a new block for under the adapter and do away with the frame spacers, but that will have to wait. that black square tube above the x-member is an advance adapter peice. advance also suppies a peice that allows for the mount of the 205 shifter, but mine isn't all hooked up yet, because i didn't get around to it.

That is awesome!

Great pics of your progress, keep up the good work and keep us posted! Also keep the little lady, not many are willing to spend time in a shop with their man giving moral support and encouragment!

I think an article for FAQ is in order. I am wanting this set-up also. Part numbers would be great.

[ryanroo]

Ok, everyone seems to want more information. here is a sort of step by step and some more pics. i will snap more photos this weekend when i finish and post them as well. if someone wants to move this to the FAQ board that is great, if not i can copy and paste it into a new thread.

As always block the truck so it won't roll, and disconect the positive battery connection before any repair/replace procedure

this is also a good time to replace the clutch, but mine is less than 6 months old, so i left it alone.

these are my steps, feel free to add anything i have forgotten.
1. remove the driveshaft
2. remove the shifter( if standard floor shift )
3. remove seat and transmission tunnel cover.
4. drain all fluid from the transfer case and transmission remove speedo cable and backup light wires
5. Remove the 8 bolts holdong the transfer case to the factory adapter. be sure to support the case, it is heavy
6. carefully slide the input off of the splined tube in the adapter and the t-case is out.
7. remove the 2 1/2 (3/4 wrench) inch bolts holding the adapter to the crossmember.
8. support the transsmission with a floor or transmission jack or cherry picker from above.
9. remove the 8 bolts holding the adapter to the transmission case and remove adapter.
10. remove 8 bolts holding the crossmember to the frame. a few of mine broke so have some WD-40 or other penetrant around for the rust. remove the crossmember
11. remove the 4 bolts holding the transmission case to the bellhousing.
12.carefully lower the transmission out of the vehicle. you must slide it strait back to remove the input from the clutch disc before lowering.
13. diconnect the clutch linkage from the throw out fork.
14. pull the starter (if block mounted this step can be ommitted)
15. remove the 6 bell housing bolts (9/16 wrench) and pull the bellhousing, clutch fork and T/O bearing.
16. Use a dolley ( i used a creeper ) to slide the new transmission and transfer case asseembly under the truck. You can either choose to put the bellhousing on the engine now or leave it attached to the case. i chose to attach mine to the engine first.
17. Use ratchet straps or chain(i prefer straps) to hoist the tranny assembly up into place with the engine hoist.
18. line the input shaft up with the clutch disc and pilot bushing.
19. slide the tranny forward and bolt it to the bellhousing using the 7/16 bolts(5/8 wrench)
20. attach the Advance adapters crossmember spacer to the aluminum adapter using 7/16 bolts (5/8 wrench)
21. bolt the crossmember to the AA adapter using the factory bolts, now with nuts and lock washers(they thread strait into the adapter in the factory application.
22. I used 1 1/2" square tube to space the crossmember down so the transfer case would not hit the cab. 7 inches long with 3/8" bolt holes on 5" centers for the spacers.
23. set the spacers on the crossmember and jack it up against the frame. drill out the frame with a 3/8 inch drill bit. For the upper frame rail i used a long shank 3/8 drill bit and went throught holes i drilled in the lower frame.
24. bolt the crossmember to the frame using new 2 1/2" bolts nuts and lock washers.
25. if your driveshaft is at the middle of its travel before you start it will need shortened, my truck had a lift and factory length driveline, so it needed no mods. the front driveline will need lengthened. I also replaced my u-joints at this time.
26. AA sells a bolt on relocation bracket for the t-case shifter, so install it and the shifter
27. install the shifter for the tranny, and re-install the interior peices.
28. re-attach the clutch linkage and starter(if removed)

All of this i for a 71-72 original 4 speed 205 combo truck, other things will have to be done if working with an auto truck.

i used all AA parts, including the transmission. the bellhousing is the left side mechanical clutch linkage part.
I will do some looking and get part numbers ASAP.
tools needed for this swap were basic hand tools, electric drill, engine hoist and an assortment of bolts and nuts.
My girlfriend and i accomplished this swap with about 6-8 hours invested.

Also this transmission requires that a special synthetic oil be used or the tranny will self destruct. here are some PN's 715690 is the AA number 12346190 is the GM part number or the Dodge part number is 4874459. You can also you Castrol Syntorque synthetic as well, but only these will work all else will ruin the tranny. It is also advised to run this oil in the transfer case, in case for some reason the seal between the two breeches. this will allow the gearbox contents to mix and possibly ruin the tranny if the same oils aren't used.

I now see the value of a lift kit in a truck I just had to pull my tranny this weekend to put in the new Centerforce Dual friction clutch. Let me tell you, even with jack stands, its pretty freakin tight under a lowered truck. That tranny looks pretty sweet man, congrats !

That's when you spend ~$1k-1.5k and install a hydraulic lift in the garage

Hey, sixseven, you got a website or photo album with pics of your truck? Looks sweet in your avatar.

[sdkid]

I work in a dealer that carries both gmc and dodge truck. I will tell you from experience that the gm part number is cheaper than the dodge number. No experience with the other two.

[FRENCHBLUE72]

That isa sweet set-up for sure you should be really happy with it.. Nice work..

[ryanroo]

I finally got this beast back on the road this weekend, had to fight a little bit with the spacers for the crossmember, and i finally located some of the special fluid needed for the NV4500. took it out for a test drive, very nice. i still need to work on a little timing bug, but its no big deal. also need to get a tranny tunnel cover for it, and a few other little things.
Will post a few more pictures when i get back to ames tomorrow.

Ryan do you think you could copy your how to and post it in the FAQ board?Great write up.

[krue]

Definitely needs to be in FAQ!

[1STtimePRo'71]

Nice Work. I will need that in the FAQ soon. Nice truck too by the way.

[hobby67stepside]

Ryan, good work. I'm curious, are you graduating ISU, moving on to a grad school in Wyoming, or what. We need industrious young people like you to stay here. Whatever the reason - good luck.

[hobby67stepside]

Ryan, never mind. I just found your answer in General Discussion. Congrats on going to Wyo Tech. That should be a fun and rewarding schooling process. Again, good luck.

[ryanroo]

Yeah off to wyotech, not sure if ill be coming back to iowa when im done or not, jsut depends i guess.

thanks for the kind words everyone. i will move a copy over to FAQ tomorrow and post as many pics as i have of the swap and the parts needed.
