Hi Ian. I just read your post regarding police impala transmission problems and have a problem myself that I thought you could answer. Today while coming to a stop for the red light (applying the brakes at 40km/hr) my 01 impala started to shudder. When light turns green and lightly accelerating again it starts to shake. It feels like I went over a tree branch. I got no codes (no light came on) but I am still under warranty. I have 5 weeks left and do you think the dealership can do anything for me since it only happened once? I see there is a service bulletin for this transmission (00-07-30-002B) but would the dealership perform this without having the problem duplicated on site? I drove on the highway just after and everything is fine. I floored it a couple of times while going 60km/hr and no hard shifts or anything? Any suggestions? I thought the GM 4T-65E was very reliable. Aren't GM vehicles known for reliable transmissions and you are recommending a ford vehicle in the crown victoria. Thank you for your usual helpful recommendations. Vince
