Well, I cracked open the book. I think a key item is that after this problem occurs you shut off the car, wait 10 seconds and then everything is running fine again. If you had TC problem it generally would be more consistent in my opinion.
So the problem as I can tell is hard shifting that begins after driving awhile, shut off car, wait 10 secs and everything is fine for awhile........so.....
TSS - Provides converter turbine shaft speed info for torque converter clutch control strategy. Also used in determining static electronic pressure control EPC pressure setting during shifts.
Symptoms: no tc engagements or harsh shifts.
--------------------------------------------------------
TP Throttle Position Sensor - if a malfunction occurs in the TP sensor circuit, the PCM will recognize that the TP sensor signal is out of spec. PCM will then operate the atx at high EPC pressure to prevent transaxle damage.
---------------------------------------------------------
ECT Sensor -- detects temp of engine coolant and suplies info to PCM. ECT sensor controls Torque converter clutch operation.
---------------------------------------------------------
Tot sensor - Transmission Oil Temperature sensor is located on solenoid valve body. the PCM reads this sensor to determine temp of transmission oil. Determines shift scheduling and control of line pressure for cold and hot temps operation. If defective complete pack assembly must be replaced.
--------------------------------------------------------
MLP Sensor can cause harsh engagements and firm shift feel if defective
In order of replacement or testing.....
1. TSS Sensor
2. ECT Sensor
3. TP Sensor
4. MLP Sensor
5. Solenoid pack
