Re: NV4500 swap is underway
Well, Larry pointed out a possible 31 spline setup I never heard of...

Re: NV4500 swap is underway
Those numbers mean nothing to me but it sure sounds like what I said before…an AA NV4500 to 10 spline 205 kit. You can post up pictures (in your own new thread that you will start) and we can try to help you.

Re: NV4500 swap is underway
Thanks for getting back to me larry so why did you replace the 27 spline for round patern 205 did it not work out for you after you replace the input

Re: NV4500 swap is underway
No sir. There was nothing wrong with the sleeve. In the end there wasn’t a smoking gun found as to why 5th gear started rattling on the mainshaft. I really had it burned in my brain that the AA collar that holds 5th gear in place did not hold 5th gear tight enough where it came loose and caused 5th gear to knurle the mainshaft resulting in all of the noise. Keep in mind the AA kit required the mainshaft to be cut where the nut (yeah, the one that is notorious for coming loose on NV4500s) that holds 5th gear is not used. Instead of the nut, AA uses a collar to hold 5th gear in place. That is where the 31 spline comes in.
Last year when I go it apart I found the AA collar was indeed tight where by hand it felt like it was holding 5th gear just fine. There was no play what so ever eventhough 5th gear would rock on the mainshaft. With that, I cannot blame the AA kit for taking out 5th gear on this new trans (this was a NOS trans, not a remain). Prior to tearing it apart I had already purchased a new mainshaft and round pattern 205 to go back together with as I didn’t want to cut another mainshaft. The question remains why did 5th gear tear up the mainshaft when it was tight? That is a good question but I am starting to believe those that claim never to tow in 5th gear. I don’t tow but this truck is very heavy (8,000 lbs.) with a high torque engine. I tend to lug it in 5th gear at low RPM and low speeds just because the engine has enough power to do that. Lugging it around also saves fuel. It could the NV4500 is not strong enough for my driving habits. If this thing craps another 5th gear I’ll be looking at doing something different for a transmission. Probably an Allison 2200 on the next swap if these NV4500s continue to be so finicky. What really chaps my butt is the trans that ate 5th gear was a NOS trans from a GM overstock buyer. That thing shifted soooo nice! Now that it has been rebuilt with an aftermarket mainshaft the SOB does not like to go in to granny gear without a fight meanwhile, the NV4500 in my Burb also has an aftermarket mainshaft and that one won’t go into 5th gear without a fist fight either. I am just about over these finicky NV4500s. So far I've got about 5,000 miles on this latest NV4500 and so far so good (other than it doesn't like to go into granny gear). Its as quiet as a church mouse in 5th gear cruising on the interstate at 80 MPH. [quote=SunSoaked;6846322] Quote:

No, I’m not saying it’s not worth the swap. There are lots of people having great luck with NV4500’s. My problems could have been an isolated issue or something related to my driving habits, truck weight, power, etc. The problems with mine not shifting worth the crap after they’ve had mainshaft replacements could be related to the aftermarket parts or maybe the guy I am using to rebuild them is doing something wrong. I think you did get a great deal on what you got.. Don’t be scared to use it. I personally am getting tired of fussing with these things. If mine craps again, its getting replaced with something else.

Re: NV4500 swap is underway
It’s in Canon City but it is closed now. One of the brothers that ran it died and the other brother closed it down. The rumor is he could not find a buyer for the entire yard so they called in a crusher and stared scrapping everything. A total tragedy and waste of hundreds of not thousands of trucks if you ask me. It was without a doubt, the best yard around this area that is for sure.

![]() ![]() ![]() ![]() Are you serious!? They crushed all thos trucks??? That is insane, with it getting harder and harder to find parts how could someone have the gutts to actually really crush them! I vote for a preservation program to save al 2nd gen and square body trucks on this planet! ![]() But honestly, that is a shame, small things like the pedal assemblies, the trim or interior stuff are so hard to come by.... Up in the north east here, they crushed about every old truck there was a few years back, so no truck of any kind older than 15 years or so around here anywhere.... Do you have any idea where else I could find OEM trim for the body and behind the cab? and also the two chrome stripes you have in your grill, haven´t been able to find any for 14 years that I own the truck now... Thanks for the info (even when really sad) Larry!

I drove out out in Colorado Springs in August 2013 to visit a friend, and because of your post we went out to Canyon Truck to check it out. I ended up finding a set of power mirrors and some fender emblems for the C10. Sadly I could not bring back much more than that because of limited space in the car. That was an awesome place. ![]() This is one picture I took, I have a few more but I don't want to muck up your thread. |

![]() One option is to purchase the Advance Adapters 205 shifter bracket that bolts to the NV4500 lid bolts but that bracket is horribly flimsy. In fact, I threw mine in the iron pile because I had my doubts it would hold up for what I do with this truck. That left me with the next option of moving to an ORD twin stick. I was not thrilled about doing a twin stick but in the end I am glad I did. The third option would be to fabricate your own bracket as a homemade bracket can’t be any worse than the AA 205 shifter bracket. The last option would be to do a high dollar cable shifter like the rock crawlers often use. Hope that helps. SM465 on Left – NV4500 on Right ![]()

Re: NV4500 swap is underway
Okay thanks. I do remember your thread discussing the weak bracket but didn't catch why the factory shifter wouldn't work. I understand now. I did read somewhere in these threads that AA redesigned the shifter bracket and is rigid now. I may go that route just because I would really like the keep the factory shifter if possible. If its to flimsy I can always figure something else out or twin stick it.
Have you ever had any experience with the 5thGearrepair.com locknut retainer? I wondered if I could use this? I'm not sure I can if I use the AA spacer between the nv4500 & np205.

![]() BUT, ya! It sucked, one of the brothers died summer of 2013, probably about the same time you were there. The other brother sent out notices to their customers around September/October where December 31, 2013 would be their last day of business. I caught wind of that through Zoomad75 who is the Service Manager at the Chevy Store in Canon City. Zoomad and another member, Ian, ran up there shortly before they closed shop and went crazy grabbing whatever we could. It is a total classic truck tragedy! Not only is it a tragedy to hear of anybody passing of cancer, it is a tragedy to see all of those trucks get scrapped. As you saw for your own eyes, they were pretty well loaded with trucks…GM trucks, Ford Trucks, Dodge Trucks, old trucks, new trucks, trucks trucks trucks….no more Canyon truck so now we are all ?ucked. Rumors come and go where someone else may fire the place back up but I have my doubts as I went by there last weekend and it looks like it is getting emptied out. It looked like portable crushing equipment up by the building. Sad ![]()

Re: NV4500 swap is underway
DL,
I was cruising different sites this weekend and somehow came across this model. I'm not into RC's, but couldn't help to think of your rig when I saw it. Heck, it maybe yours for all I know. Nonetheless, here you go.
