Hi i have a 1996 chevy 1500 4x4 350 vortec 131,000 miles . i just got truck so i am not sure how it ran before i put the tranny in . but now i put trnny in and it went fine for the first 2 days exsept it shifted hard into second and third but nice into overdrive .then the next night it wouldnt go into od but went through the other gears ok . then the next day it wouldnt shift at all unless you shifted by hand then od worked fine . then it worked fine later that day uou put in od and went fine through all gears but then a couple days later it went back to not shifting . and when it dont shift own own it will manually and abs light comes on and speedometer don't work . i read that this might be the tps ?
