Guest almostwon Posted March 16, 2006 Report 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
Regal_GS_1989 Posted March 17, 2006 Report 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. :? Quote
