6669charger Posted December 14, 2011 Report Share Posted December 14, 2011 My 96 sts stopped shifting higher than 2nd gear. I changed solenoids, no change. The car has lots of problems, the blower and cooling fans dont work either. Could the trans be an electrical or ground problem? Going to scrap yard if I cant figure this out.

rpcm2108 Posted December 18, 2011 Report Share Posted December 18, 2011 Just repair my Seville yesterday, had same exact problem. Does your check engine light come on when the transmission should shift from 2nd to 3rd? If so, its exactly the same problem I had. Your B solenoid in the tranny is bad, but you need to replace both solenoids at the same time. You must get them from the dealer, because there is an updated relacement kit that now has a new bracket and bolt, along with new filter that needs to be installed. Getting them from the parts store wont work, they dont have the new bracket or filter. The updated kit cost me $84.65 and it took about an hour and a half to do in my garage with jack stands. Extremely messy job, but you'll save 2 to 300 dollars doing it yourself. Hope this helps. Link to comment Share on other sites More sharing options...
