I have a 2006 2.4L P.T. Cruiser (conv) that has 44700 miles. I have a check engine light that points to the problem being the transmission control power unit undervolt.

Asked by Brian Jan 23, 2014 at 07:32 AM about the 2006 Chrysler PT Cruiser GT Convertible

Question type: Maintenance & Repair

For 2 months I did not drive my car. I
started the car every week for the
battery charge. 2-3 weeks before I
had finally had the $ to go get it
checked at Chrysler I went  to start
the car and the battery was dead.
After being jumped I saw they the
check light was off. I drive for over 20
miles and nothing. About 3 weeks
later it came back. I disconnected
the ā˛•terminal for a few hours and
when I reattached it the check light
was again off. The next time it was
abut two weeks and now about 5
days. The transmission runs great,
sounds great and feels great.
Besides spending a boat load of
cash is there any other way to fix this
for good?  Why is it happening and
why does draining the power work?  
Please help. I am planning a long trip
in the spring and I don't want the
specter of a check light that could
happen at any time. Is the module
expensive to replace??

Disconnecting the battery is erasing the memory in the cars computer. That's why the CEL is off after you do that. It doesn't come one right away because certain malfunctions need to be present for a certain period of time before the computer turns on the light. As to why the code for the TCM is there, I cant say. I haven't encountered that one yet.
