So i finely get my car back from the dealer shop since being there for over a month. While being there to replace the rear sunshade assembly it was noticed to have a knock coming from the transmission while putting in park. Unknown where exactly the noise was coming from my car a 2010 XFSC w/ 22500miles had to stay. Well luckily the car is still under warranty. The dealer ran some computer testing to find a fault in the tranny. What took the longest was the fact that it had to ship from across the pond and during the two holidays(christmas and New years). Im putting it out there just incase someone else has heard this noise clunking when placed in park and has no clue. Take it in you might just get a new transmission. Good luck. Thanks Jaguar PS: get a good loaner you may be in it for a while.
