Abrupt down shift most of the time after getting up to operating temperature when accelerating after reaching desired speed. Also it goes to neutral first for a split second causing a more severe down shift. Two years ago I had this same problem my mechanic change from Mercon to the older style oil and it solved the downshift. Now it is back and worse. My car is all original factory parts except aluminum radiator and mufflers no other parts have been changed or modified.
have the same problem?
