2007 Mercury Mountaineer Base 6 Cyl 4.00L
Transmissions & Drivetrains
Transmission and fluid is fine, why is my Mountaineer jerking, not shifting right and wont accellerate sometimes?
The car bounces hard while idling, vehicle slips, fails to shift up when it should, the vehicle will jerk forward at stoplights if the brake isn't pushed in, and the RPM's are way above the normal - sometimes up to 2000-2500 at only 25 mph. Mechanic says there is nothing wrong with the transmission
