Default Downshifting hard at 30mph when coasting

When I'm coasting to a red light, say from 45mph, and my SUV gets to about 32mph it feels like it either downshifts 2 gears or brakes are applied (I know the brakes aren't applied). The slowdown lasts until about 22mph then it releases. Went by the Dealer and they said it may be brake assist but I don't see that, They put it on the computer but didn't get any error codes.

Any ideas?

well, if you dont have a hand held scanner you can disconnect the neg. battery cable for a while. then let it re learn your driving style. the only problem with doing it that way vs a scanner is you will have to reset your power windows.

clean your caliper slide pins, might help a lot. i recently cleaned and greased with silicone paste and the drive feels much smoother now.

Have you selected Sport Mode? This will affect shift points and intensity.

How do you reset the Windows? Never heard of that.

Hold the switch to put the windows all the way done, then all the way up. The auto up/down feature should work after that.
