I don't know, but those are famous for weak trannys- take it to the dealer and have it checked- you DO NOT want to be taking any chances-

Ill tell you. Ford!!!!! The engine and tranny on a jag are ford. Junk.... Might as well have bought a freakin thunderbird (junk) this is what happens when people buy a name. Jaguars used to be awsome cars. Then the nineties came around and they learned how to duck taxes. They partnered up with ford, and then Jaguar went to shit. $80,000 pieces of junk. Built by an american car manufacturer that builds cars to save money. Not make money. Btw. Just a little trivia. When was the last time jags were considered quality to anyone other than people who want to look like they have money they do not have? Answer: back when they were supercars. (you know..... Before Ford got ahold of them).

well, I could not afford to own a 21st Century Jag, Rover, or Audi- nor would I want the stress- having said that, these examples must be viewed against the vast backdrop of ALL 21st Century cars- plastic, electric, pieces of kleenex-

Gear Box Default...been there...new to me Transmission...did that. Problem solved. Get a rebuilt transmission from a reputable mechanic for less than the cost of a new one. Must be reputable though. Don't gamble.
