CEL on, torque converter stuck in lockup
Just got my truck back together after an injector swap.
Truck still taking a few extra cranks to fire, but CEL comes on right as it starts.
And the torque converter seems to be stuck in lockup.
Put it in reverse, and it wants to stall. Drive it, and shifts hit HARD.
I put a meter on the wire that the EEC uses to command the torque converter to lockup, and it is HOT. Not grounded out when put in reverse. (TC should never be locked in reverse, right?) So it seems the TC is locked up, even though the EEC isnt telling it to.
No codes stored.
And I dont have a code reader to scan engine running codes.
During the injector service I did nothing trans related. However, during the initial cranking, working the air out of the HPOP oil system, the truck did start, and the throttle pedal went numb. Shortly after, the CEL came on.
I pulled the pedal assembly, cleaned the idle switch and tps, tested them with an OHM meter (seemed okay) and reinstalled.
