Try getting the transmission reflashed. This will clear the adaptations as well. It is incorrect that the transmission stays in 5th while in sport mode. It will go in, just takes a little more time. When you get it flashed, there is a specific driving cycle you as the owner must perform beyond what the Jaguar tech has to do. The first time I had mine flashed, they forgot to tell me and I didn't read it in service manual until it was too late. They did it again, and remembered to tell me that time. I had also read about it in the service manual.
The "sport button" is nothing more than a trigger to the TCM. Really nothing to break...

Just to wind up this thread - took the car to the Vancouver Jag dealer. Service Manager asked whether the lurch was still a problem (No), asked whether there were any other tranny problems (No), then said he would be glad to do a reflash but didn't think it would be of any further benefit and might actually lead to accelerated wear on seals, etc., as the tranny would consider itself new again!!
I still can't believe what I heard, but he's the expert and has been there for a long time. Was it false economy to have saved $150?
