My 17 Jaguar was stuck in reverse and would t move into park. Purchased a replacement off eBay for $125. Carefully dissembled console area and unplugged old gear selector. Installed replacement and was good to go. Later I took apart the inoperable selector and found that inside there are 2 springs with a little plastic piece on either side of the sheet below the knob. One of the plastic pieces had got caught and fell out making the knob not move. Easy fix anyone can do…well most anyone. Dealer wanted to charge $700 for part and then labor. Easily aaved myself a grand.
