Air Conditioner problems of the 2003 Jeep Liberty

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.

2003 Jeep Liberty 4 wheel drive. Air conditioner smells inside of vehicle of mildew. Had vehicle serviced 4 previous occasions by dealer central valley. 5th time had serviced dealer to replace air condition unit. Odor was noticed a few months after purchase.

On 5-6-03 I purchased a 2003 Jeep Liberty. On 5-29-03 I took the vehicle to the shop for the first time(995 miles) for a possible missing in the engine. Tech found the a/c overfull but no miss in the engine. The a/c was discharged and recharged to the proper level. This did not correct the problem. Every 8 to 10 seconds the engine surges( what feels like a miss) and more frequent with higher rpms. The second shop visit was at 1,420 miles with same problem. No fix! the third shop visit was at 1,941 miles with same problem. No fix! the fourth shop visit was at 2,089 miles with same problem. No fix! the fifth shop visit was at 2273 miles with same problem. No fix! on the fifth visit a chrys. Service rep. (jim dupree) kept vehicle for two days. Found the pressure in the a/c is going from 140psi to 180psi in less than a second which is what causes the jerk(miss) in the engine. Cause: a sensor that controls the a/c compressor. This could possibly be causing the very low gas mileage(17mph on the highway). As of 9-12-03 I have not been informed of a fix. I was advised by the chrys. Cust. Service phone line the matter had been turned over to the dist. Manager matt witters and he has made his offer of a trade to a different type vehicle. I have never spoke to him in person or by phone. In the past several weeks I have been trying to find out what chrys. Is doing to find a fix but I have been unsuccessful. Numerous attempts to contact mr. Witters has failed. I was also inform mr. Witters has tried to contact me but it has always been at times he was told not to call. I do not want to trade for another chrys. Product that I did not want to began with or I would have purchased another type. I want them to repair the one I have, give me another Liberty(without problem), or give me my money back. That is not asking too much. I have been unsuccessful in getting any response over the past month.
