I have seen the New Process A-883 overdrive 4 speed manual transmission mentioned quite a few times here and I was wondering how strong it is. I know they used the GM version in various light duty vans and trucks in the '80's but the biggest motor would have been maybe the 305. My cousin in Pittsburgh is a Mopar maniac and he says it is junk. He says even though they used the Mopar version behind the Hemi in the '60's it was problematic. He said he would not use it on anything bigger than a 360. He further says the GM version is worse than the Mopar version. The reason I ask is I have a friend with a Pontiac 400 in a '77 Trans Am and he wants an overdrive manual transmission. I thought this trans would be a good way to go until I spoke to my cousin. Is he right or an is he an idiot?
