When my X is cold and I go from reverse to drive (with a pause) sometimes the tranny feels like it is slipping. The RPM's go up but the car just crawls along. The X is an early 03 3.0i and has 29K on the clock and I've had it for just over 1000 miles. I have come to learn that there is not a dip stick to check the fluid to see if it is low. Is this a common problem??? What does this sound like to you???
