Guest almostwon Posted March 16, 2006 Report Share Posted March 16, 2006 Hey everyone. I have a problem that I hope someone can help with. I have a 94 GP SE with a 4spd auto. When I first start out from a cold start it starts in second gear. After it shifts out into o/d it only stays there for about 5 miles then shifts back into 3rd. After it warms up it shifts fine but will not shift back into o/d. With gas prices going the way they are I need o/d. Please help. Oh... it shifts fine and does not slip at all, amazing considering it has almost 250,000 miles on it. Quote Link to comment Share on other sites More sharing options...
Regal_GS_1989 Posted March 17, 2006 Report Share Posted March 17, 2006 Sounds electrical to me. There are two solenoids in the trans that control the shifts. I dont remember what the on/off combination of them are for each gear, but it may be possible that one has failed, or fails only when it warms up. It could also be a short in a wire going to the transmission, or even a bad ECM. Electrical problems can be sorta hard to locate sometimes. :?
