TH350 Warm Shifting Problem

My TH350 runs fine when first starting out: 1-2 and 2-3 shifts well under normal driving and WOT. After it warms up, it frequently downshifts while I'm maintaining a steady speed. I can get it back into 3 by shifting to neutral and back to drive, but it will shortly shift back to 2. Also, it won't 2-3 shift at WOT after it's warmed up. Any help is greatly appreciated!

See I told ya! GM is playing a trick on us! All these TH350 were meant to go bad at the same time!

Has this trans seen regular fluid changes? If not try pulling the pan level and try not to lose as much of the original fluid as possible. Take the filter off and see if it isnt half covered with crap.

Other than that I still think it's a GM consiracy! Or TH350's really do suck! (thats opinion)

TH350 Warm Shifting 2-3 problems

I am seeing this same issue with my 78 chevy 4x4.
Has this been diagnosed?

IM WITH YOU ON THIS.

Does the car over heat a bit on a constant level. when was the last time you drained and refilled. does it jerk out of gear or just kinda slid into another gear. do you abuse it . do you have a tranny cooler. how many miles does its have. has it ever been rebuilt, with what. why dont you get a 200r4
