MODEL:

M. YEAR:
2003-2004
SUBJECT:
TCM DTC 0053, Lock Up Pressure Switch Stuck
DESCRIPTION:
The voltage from the pressure switch in the transmission (PS4) should be 12V when the Torque Converter Clutch (TCC) is off, and 0 V (ground) when
the TCC is on.
TCM DTC 0053 is set when the TCC is commanded to be off, but it is measured to be on, based on the voltage from PS4.
If the Lock-Up Solenoid is faulty, the torque converter clutch will be on, and the voltage will be grounded, whenever the vehicle is in 2nd, 3rd and 4th
gear.
