    so i've found 2 early 90's chevy 1500's with 5 spd trannys and im considering swapping out my turbo 400 for a manual however i dont really know alot about chevy's manual transmissions except for the sm456. my guess is that these trucks have the nv4500? or do they have something else that i dont know about? these seem to be way to cheap though beacause from what i've heard the nv4500's are pretty pricey. any help would be great thanks guys!

    If they are 1/2 tons they arent' 4500s. They are Getrag 5-speeds, good for a driver, but dunno bout a wheeler.....

    thats not always true

    some 1/2 tons had the nv4500, especially if it a w/t 4x4 and if so you've found a 14bsf with a 6 lug also.

    i'm assuming that the 90 models are 4x4? other wise how are you going to get it in? or are you looking to swap a tranny in a 2wd?

    Unless they made 1500hd's then they didnt. that would be a light duty 2500

    thanks for the help! but from the sounds of it they arn't gonna be the nv4500's however i suppose i'll check anyhow just to make sure i dont pass it up. anyone know about the getrag 5spd? im looking for a tranny with a lower first gear than the 400... otherwise i'll just stick to the sm465

    I used to own a 94 chevy 1/2 ton with a NV4500. It was the only non 1/2 ton part on the truck. It was an option that only a few people went with. Loved that granny gear.

    The 4500 was an option on the 1500's starting in 92- possibly late 91. The 6-lug SF14 was an option too, from 88 til 95 or so. You can ID it by looking at it, it has a large black iron case with an separate aluminum bellhousing. The LD 5-speeds are one piece with integral bellhousing and are bright aluminum. They were offered starting in 88 or so. I've beat on one pretty hard- hard enough that I destroyed the open 10-bolt behind it and though it showed signs of wear it never gave up. You should be able to bolt one up to a NP208 or 241 out of an earlier truck to do the swap. The main problem area is the internal slave cyl on some of the later year models. I had to replace the slave on my 93, but it was external- I just had to loosen the starter to get it completely out.

    I'm swapping my built 400 for a 465 too. 465's are a dime a dozen, I wouldn't trust a LD 5-speed and a 4500 is $$$.

    .10 a dozen

    well i'll take about 5 dozen, i just barely have 2 quarters to rub together, but i guess i would part wit em for 60 sm465's, i've been lookin for just 1 for about 2 years now that has a 203 adapter so i can do my crawler with a doubler!! they just not in this part of the country!...

    i've been told that the 400 with the 203 adapter is the way to go anyway, when you realize your in to low of a gear and your sinking and you have to clutch it to grab a gear might be just long enuff to stick you there once you lose that momentum, with an auto if you realize your going to slow you just gas it!!
