Nv4500 conversion

[Indyfab]

I’m wanting to convert my 1981 GMC crew cab from a sm465/np205 to a nv4500/np205 combination. I have no trouble finding the adapters needed, or performing the actual work. What I am having trouble with is finding a reasonably priced nv4500. I am not wanting to pay $2500-3000 for a remanufactured transmission when I can do the rebuild myself for way less. I’m needing one out of a 1996-2005 gm 4x4, or 2001-2005 dodge 4x4 with a gas engine (not a V10). If anyone could point me in the right direction I’d be very appreciative.

they are hard to find but do come up on craigslist from time to time....I just bought a newly rebuilt one last week...by the time you pay core charge they do get pricey....its cheaper to pay the core charge than buy a junker for a core....
you might also check with http://car-part.com/ ...its a search

just did this swap in our 79 last year

they pop up on clist from time to time. I lucked out and got mine for $450 I think. BUT i ended up having to get it rebuilt. so I'm into it for close to $2k anyway. if i had to do it over I'd buy a rebuilt one from the start. 2 years unlimited mileage warranty on my rebuild.

keep a eye open for 88-98 body style trucks that are the W/T = work truck . lots of them had a v6 engine but had a nv4500 in them . my buddy got one for 350-400 bucks once from a guy parting one out . pulled the top cover and it was almost new inside . baby motor and didnt get beat on as much .

Thanks for the suggestions, I thought 92 was the first year for the nv4500? And in 96 they switched to the higher first gear?

96 and up is the better of the two....the earlier ones had issues....usually when rebuilt by a trans company they do all the upgrades

Such as? I know 1st gear ratio was too low for most but in my case it's not an issue.

[mongocanfly]

3rd and 4th syncro rings and 5th gear were the main issues if I remember right...and the low gear 1st was a drawback as well....when I bought my 1st
nv4500 everyone told me to stay away from the early ones and always go with the post 96s
