MERCURY SABLE PROBLEM

2002 Mercury Sable • 186,000 miles

My car started to have problems shifting when accelerating fast. As long as you ease into the acceleration no issues as of yet. But when the car its about 2800rmp it shifts up a gear then back down until you let off the pedal and then ease into it. I see it most trying to accelerate say to pass a car or on a hill. I have changed filter and fluid in tranny as well as added a sea form type product for tranny's.

It could be valve body issue or internal failure. Have a trans shop take it for a ride to confirm
