98 gmc jimmy/blazer NEED HELP wit trans problem ASAP
Ok i have a 98 gmc jimmy, it throw the p0785 code which is a solinoid in the trans i have replaced the 3,2 shift solinoid, and it stills acts up ( the check engine light comes as soon as u start the truck and after u drive it a few blocks the truck stays in third gear and doesnt shift,) so people said it could be a bad pcm, i took the pcm out and had it cleared and reflashed, put it back in and 5 mins later the light came back on and problem still there, if i leave the obdii scanner on it while im driving i can keep erasing the code and the trans is fine but the light comes on within seconds, need help asap any ideas of what i can try i dont wanna keep guessing and spendin more money thanks in advance o and its only throwin that one code p0785
