37- Torque convertor clutch solenoid circuit. An open or shorted condition detected in the torque convertor part throttle unlock solenoid circuit (auto trans only).
Thanks Timdog. Yeah, the old Ramcharger is acting up. It seems to be surging when I'm at idle waiting for a light to change and when I'm on the freeway, it revs up and down like it is searching for overdrive. I am going to change the oxygen sensor because it is due according to the Maintenance schedule. I'll see how that works and kind of go from there. [
I already replaced the cooling temp sensor about 2 weeks ago. If the new one is working correctly, would the trouble code still be coming up? I thought maybe it takes a couple of weeks for the code to disappear from the computer.
If you go to your local auto zone they can put a scanner and erase the codes. Its better than disconnecting the battery. After the codes are erased drive it around and recheck the codes. Then tackle the work.
