Hello, I posted in Lt-1 tech, no results. But my car sometimes will not go into overdrive. I had Bryan at Pcmforless redo my computer for my small cam and he changed the shift points-used to go into overdrive around 45mph now around 53 or 55mph. I got the transgo shift kit installed, but had the three washers removed, kit still in. I e-mailed Bryan and he said it sounded like my overdrive solenoid was going bad. Sometimes it will go right into overdrive at 55, then sometimes it will wait and do it later. I got a good size tranny cooler, would that keep things from heating up right to go into overdrive? Where is this solenoid? Something loose? Thanks for any help/ideas--Dwayne
