DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
2002 Jaguar XJ8 BaseFACTORY OEM SERVICE PROCEDURE
Control Systems: Operation
CAUTION:
Disconnection of the TCM and/or the vehicle battery will cause system adaptions to be lost; this may be apparent by shift quality degradation. Following reconnection, a period of "varied" driving will reinstate adaptions and thus normal operation. Please ensure that the customer is made aware that the adaption period is variable and may occur after hand over, as the transmission re-learns the prevailing driving style.
