is the car lurching foward.. at what speed? or when you downshift you have a harsh downshift? ... into 1st .. it seems all there doing is clearing the shift adaptations and reprogramming the tcm and ecm... really not gonna fix this... do they know if the correct software is in the tcm...? the car needs to be cleared of the shift adaptations.. then has to go thru coded access .. thru jaguar hotline..

That is the other side of cutting edge. The upper end manufacturers invent all this stuff, then the other manufacturers copy it once the kinks are all worked out. Since they are the umpteenth company to better the design, it works better. Creativity is tough, making a quality copied part makes cars affordable for all of us. Remember the day when only those fancy cars had electric windows? No, it's hard to find a car without them!

That's what I was wondering? It seems good that they replaced the transmission, but amazing that the problem wasn't solved. I'm glad my 2003 doesn't do this. However, it does sometimes seem to lurch when I come to a stop. As I press the brake the car feels like it jumps foward a bit.

My 03 str does the exact same thing. When the car is just about to stop I get a slight jerk forward. What I think it is is the car downshifting into 1st gear just before stopping giving the nudge feeling. Next time you drive pay close attention and see if you think that this is what yours is doing.

you could try the manual shifting using the jgate, so when u want to come to a stop slowly shift down on the jgate and see if you still get the "nudge feelin"

Since the J gate starts at 2nd gear it still shifts in and out of 1st automatically and still does the same thing. If I just roll in first and then stop It doesn't seem to do it.
