The 'kick' is the transmission slamming into 1st gear upon throttle appliation after doing a rolling stop.

My transmission was replaced under CPO for this.

Some people have found that resetting the transmission adaptations can help (search here -- QSilver has posted the procedure). Some people have reported decreasing the severity by changing out the transmission fluid (procedure also available in this subforum). However, changing the transmission fluid has its own risks so read up first. You'll want to use the appropriate Lifetime6 fluid (I'm guessing your transmission).

What engine do you have, the 3.0 or the 4.4 (or 4.8)? Put the details of you X5 into your signature please, it helps when we're remote diagnosing issues.
