Torque Converter Clutch Solenoid Circuit Failure
On my 1994 5.0L f150 (E40D) I'm getting this code 629 Torque Converter Clutch Solenoid Circuit. The problem I am having is that, when I put the truck in drive, the truck dies (Like Drive is a kill switch). I can put it into 1st then 2nd then Drive, but when I come to a stop I have to throw it back into 1st it will die.
Classic rookie DIY'er I went and started throwing parts at it. I replaced the solenoid pack, filter, tranny oil and oil, and the rig is still doing the same thing. If I disconnect the passenger side wiring harness, that would tell me if problem is in the solenoid. Since the solenoid pack is new, If I go dissconnect the solenoid pack and the problem goes away, that would mean the problem is where????
In the wiring harness somewhere?
I'll go check...
If anyone knows howto remedy this problem my stepson would be most greatful, this problem developed on his 16th B-day. Poor guy hasn't been able to drive his truck to school (or anywhere) as a licensed teenager.
