show me proof of this. i have never seen a truck post-88 that had a 3 speed that WASNT a TH400, nor have i ever seen parts for a post 87 TH350. the catalogs i currently have have no mention of one after mind you i worked for a GM parts department for 2 years, an AC Delco dealer for 6 months, as well as spending my high school years in a grease pit at Jiffy Lube. i have NEVER seen a post 86 TH350.

seems to me nobody lists them for anything after 1986. hmmm, i wonder why that is.

And as far as the transmission crapping out, that doesn't necessarily mean poor maintenance. It is the nature of mechanical things to fail, no matter how well maintained.

true, but a religious maintnance routine has been proven to make machinery last longer. being a TH400, its the beefiest of the beef. it broke, which isnt all that common. maintnance probably played a factor in it. the abuse didnt help, but it isnt the sole reason for it.
