WARNING: This page is about a different car, the 2015 Jaguar XF, 2014 Jaguar XF, and 2013 Jaguar XF. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
  • Slight surface oil dampness without drops are acceptable and should not be repaired as a leak.
  • Be aware that oil leaks from above the transmission will cause oil to collect on the transmission oil pan i.e. engine leaks, oil cooler pipe leaks, even diesel fuel leak.
  • Fixing the incorrect leak does not satisfy the customer.
  1. Remove the transmission undershield to gain access to the transmission area (Refer to Air Deflector (Front End Body Panels, Removal and Installation).
  2. Using a suitable degreaser, thoroughly degrease the transmission oil pan and transmission oil pan seal all the way around the transmission, as well as approximately 25-50mm (1-2 inches) above the seal.
