The transmission pressure control solenoid may fail causing erratic shifting. Our technicians tell us that partial dis-assembly of the transmission is necessary to replace a failed pressure control solenoid.

Sometimes after going really fast in the car, when the car comes to the stop then go again he car seemed to move but the gears are like stuck and making really weird noise
my transmission intermittently shifts hard in all gears.
