Love it but can't trust the sucker!
I have a Jaguar 2002 x type that runs great for weeks/months, then all of a sudden it will stop shifting like there is a transmission problem.Dash warning says,"gearbox fault". Had it checked and after clearing the codes, the trannies could find nothing wrong. Could this be an electrical problem? I bought a cheap code reader to clear codes when it happens next as this is easier and faster than disconnecting the battery and waiting. Thanks for any help!
