full bulletin at NHTSA ↗This Preliminary Information communication provides information to the technician about vehicles that may have a delayed engagement into drive, shudder at a launch, or the transmission is slipping when shifting into 1st, 2nd, 3rd or 4th gears. This may be due to loose stator support to pump cover bolts causing a leak at the stator support to pump cover gasket. Technician will check for the bolts to be loose. If any of the bolts are loose or the gasket is misaligned or leaking, the transmission pump cover must be replaced and the 1234 clutch plates should be inspected for being distressed and repaired as needed.

The vehicle hesitates and shifts harshly as if it will stall at low speed acceleration leaving my driveway and when going forward from a full stop at red light to green. Very jerky ride, uneven acceleration, fear of stalling.
Transmission slips on inclines. Have taken it to dealer several times . They changed fluid and it still slips on inclines. Doesn't slip all of the time, but does still slip! This started approx. 2 months after purchase. Bought new.
Truck jerks and makes loud noises when going up incline when transmission is shifting and constantly shifting even at low speed.

At what mileage does the powertrain typically fail?
Mileage data is limited for this issue. Owners report failures across a wide range, suggesting cause is more about driving conditions and maintenance than mileage alone.
