Gearbox oil
Worn oil or a low level upsets circuit pressure and makes shifts harsh.
COMMON FAILURES01 02 03
Automatic gearbox that hesitates
A sharp jolt when a gear engages, a box that hesitates before taking up, or revs rising without the car accelerating: the behaviour describes the trail to follow.
Possible causes
Control unit
A tired control unit or computer can drive the gearbox clutches imperfectly.
Converter or clutch plates
Slipping, with revs rising but no acceleration, points to the converter or the internal plates.
