I own a 2003 Jeep Liberty and have had it for 2 years now and have every problem you can think of. My warranty recently expired 6,000 miles ago. My warranty expired at 75,000 miles and at 78,000 miles my air conditioner broke and had to replace that it cost me $900. 00. Just yesterday may car would not shift passed second gear, I have an automatic transmission, I noticed it when I was getting on the highway. Lately I have been noticing that the transmission seems to be slipping but never could find the problem because my transmission fluid was always fine. So yesterday I went to aamco transmissions and they said it was the tcm so they told me it would cost $440. 00 total. So they went to order the part but come to find out no one has it and the place that has all the tcm parts wont ship them till the 24th of September. So here it is September 3rd and I wont have my car fixed for the whole month of September. I don't understand why they wont ship them now. Also, they told me that they have been selling out of tcm fast because everyone is always needing them.
Contact states while vehicle is in park I will accelerate. The local service dealer reprogrammed the powertrain control module. However, this did not remedy the problem.
