My 1996 Jag xj6 was working fine until I stopped for gas. When I left the station, I stepped down on the gas to quickly accelerate to highway speed, the car would not shift out of third gear. Now it starts off in third and stays in third. I don't think it is even starting in second (in Normal Shift Mode) and it won't start off in first gear in (Sport Shift Mode) Can anyone give any suggestions on what broke or came loose and where the shift cable or vacuume lines are located? I had a 1990 Pontiac act similarly and it was a vacuum line that came lose. I had a 1987 Ford van E150 that had a similar problem and it was a shift cable that broke. I don't know that much about the Jag yet, but I guess I'm going to have to learn. I am sure I can fix it the issue if I can only find the problem.
Any help is appreciated.
Thanks,
Terry

Terry,

Welcome to the forum. When you get the time go to the "new member area" and do your intro thing. It keeps the moderators all warm and fuzzy, and is just a good thing to do.

I would also suggest posting this in the X300 section, which will see a flurry of answers/suggestions to the issue.

My thoughts are:

It is an electronic transmission, so NO vac lines to worry about.

The trans fluid is probably in dire need of a drop and refill. Fresh fluid does absolute wonders in my experience.

Does the trans manually change if operated in the LH side of the "J" gate?.

Sometimes disconnecting the battery for a few minutes resets the ECM's, sometimes not, worth a try in my opinion.
