I have exactly the same problem. Is there an aftermarket chip that can be purchased and plugged in to help run the transmission cooler? If so, where and how much?

Thank You

I am sorry if something like this has been posted before. This problem just started a couple of weeks ago. My car runs great, and shifts smooth until I drive for about 45 minutes to an hour on the highway, about 65 mph. Then I will get into town when the car will be shifting alot and it seems to slip a lot, 1st to 2nd, 2nd to 3rd. It makes a big jerk. Is this slipping? If it is, should I do a tranny flush? or do you recommend something else? The Mystique has about 90,000 miles on it now, and I don't think the tranny fluid has ever been flushed or changed, at least not since I've had it (40,000 miles.)

Again I am sorry if this has been posted before, but I didn't know how to search for this problem.

Any help would be great.

Thanks,

Nick
