I have an 01 xjr i just had my trans replaced with a 60k trans. After the install i have no forward gears the place i bought trans from says he has no problem giving me my money back but he says it needs to be reflashed so the car can communicate with it. Can someone please let me know if this is true or not. Ive talked to a Jaguar dealership they said 02 and down are plug and play 03 and up need to be reflashed.

You need to post in the X308 forum where you should get replies.
