drive train on 2006 Jaguar X-Type

had the transmission and transgear box changed. now the car drives forward, but when you put it in reverse it jumps and won't reverse. HELP, is there a reset button to reset the system? or is there something else that needs to be checked or done?

return to the place that did the work. you have issues with the trans or rear end.
