My wife has a 2005 X-type. I bought it new, so we're the only owners. It has approx 60K on it now, but it's always had this problem. Sometimes it feels like the transmission slips when making a turn or otherwise coming off the throttle, then re-engaging the throttle. It basically revs up then dumps the power back to the powertrain causing a very noticeable surge and thump in the tranny. It's been doing this since new. Every time I take it back to the dealer for service, I mention this, but since it's very intermittent, they haven't found anything. I guess it won't be properly diagnosed until the car goes back on a flatbed one day.

Has anyone else had this issue? Thanks in advance.

check the transfer case level , mine was mis diagnosed as a tranny a transfer case drain and refill solved the problem

 

My wife bought an 02 XType in 04 with approx 30K. Tranny began the slip problem around 50K and died around 55K. Unknown to me she had purchased extended warranty w hich covered the new one. Caught a breakIt seems to be a common problem.
