What is the problem if after your 1988 mercury grand marquis shifts out of second gear the car is very choppy after that when you accelerate?
If a 1988 Mercury Grand Marquis shifting out of second gear gets choppy after acceleration then the overdrive band may need servicing. An overdrive band that is sticking can also cause this problem.
