Hi,
That makes sense. Above it says SW2. Now I found the correct engine and the code is relevant. LOL
Okay, the code is related to the pressure control solenoid. You asked if it should be set immediately after clearing the code and the answer is no. For the code to set, the shift time has to be greater than 0.65 seconds at maximum pressure, for a total of two times during the same ignition cycle. Therefore, it has to be driven.
You clear it and it works perfectly until it is shut off. Then it starts over without driving. It leads me to think it is electrical (a short) which could be at the PC solenoid, PCM/TCM, or between the two.
If I had this, first I would inspect the connectors at the PCM/TCM. Make sure they are tight, clean, and not damaged.
Next, confirm the wiring between the module and transmission is not damaged as well as the connector at the transmission.
If that checks good, then I would drain the fluid and remove the PC solenoid valve and see if it is damaged in any way and if there is a wiring problem in the transmission.
Let me know if you have already done these things.
Take care,
Joe
