I have a 2006 PT Cruiser with 103k miles. I purchased the vehicle from the previous owner well over a year ago. The previous owner was religious about maintenance and most of the 40k he put on the vehicle were highway miles.
The other day I repaired some issues with the vehicle. My Ex put sugar in the gas tank after a fight we had and I pulled the tank, cleaned it, inspected it and replaced the fuel pump.
Also, while troubleshooting a rough-idle condition, I pulled the intake manifold off and checked the spark plugs. I found a leaking valve cover gasket, replaced it and all 4 plugs. While the plugs were out I cleaned out the plug tubes (2 were filled with oil from the leaking gasket).
Once the job was complete, I started the vehicle and revved it to clean out the oil/cleaner mixture that was in the combustion chamber. As expected, the MIL came on and the codes showing were a C-4 misfire and a B1/S2 O2 code. Both expected because of the contaminants in the combustion chamber. I cleared the codes and took it for a test drive long enough to complete the I/M Readiness monitors with no issues.
Shortly after completing the test drive, I took my grandmother on a drive with the car (it's going to her) and the MIL came on and the trans went into limp-mode.
Scanned the code when I got home and it was a P0700 MIL request from the TCM. Unfortunately my scanner is VAG specific and can't read the Chrysler TCM. I cleared the code, checked the fluid level, checked the harness connectors at the transmission (just in case, even though I hadn't messed with them) and took it for another test drive.
The transmission seemed to be shifting smoothly, but since I was paying attention I noticed some odd qualities to the shifts. The shift from 1st to 2nd seemed to lag a little bit, but there was no increase in revs or hard shift like you would see in a failing shift solenoid. I also noticed a shudder under hard acceleration (akin to a resonant shake like when a tire is out of balance). Other than that, the car ran well. My grandmother drove it today and it went back into limp mode.
I am attempting to find someone local who has a scanner I can borrow to scan the TCM, but I figured I'd share this issue here to see if anyone could shed light on common Auto Trans issues with these cars.
The Transmission was serviced at about 75k miles (right before I purchased the car). It has given no issues in the time I have owned it until now.
My first impression from the way the vehicle is acting is a failing Torque Converter, or possibly a failing pump.
Any input would be much appreciated.
Regards.
