Have a quick question to run by the Cutlass Supreme guys. I have a 1988 V6 2.8. While driving over 35mph, when I slow down a little then speed back up, I often feel a jerk or clunk possibly in the transmission. Kind of like the transmissionis trying to catch up with increase of speed. However, this does not happen if I accelerate from a slower speed or from stop. Has anyone experiences anything similar? Oh, I do routinely change the transmission fluid. Thanks for any help.
