I have a 2003 XJ8 that I bought recently. 45K miles on it. I find that when I start it up in the morning, the rpms are about 1000 or so (quite normal, I realize) and when I put the transmission in reverse, the car lurches. Other than that, the transmission shifts fine, with no hint of problems others have had. Since the car is still under the new car warranty, I took it to the dealer and was told "they all do that." Well, of course, that's nonsense. I am guessing that the accelerator pedal sensor output to the transmission control module is messed up somehow, telling the TCM that I have my foot on the gas when I don't. But this is only a guess. What's clear is I'm going to have to help the mechanics solve this problem, so I'm hoping someone can point to something that I can have them check out. Is my guess reasonable? Are there other things I should have them check? It is clear to me that "they DON'T all do that", so I need some information to get them to actually look at something rather than brush me off. BTW, I am dealing with Thousand Oaks Jaguar, if that makes a difference. Thanks for any help you can give.
