Hazard
In the automatic transmission, the transmission fluid pressure control program in the engine control computer is inadequate, causing transmission fluid pressure to become excessively high during gear shifting. Repeated use involving rapid acceleration and similar driving can damage the clutch inside the transmission, resulting in poor acceleration. In worst cases, the vehicle may become unable to operate.

Remedy
All vehicles: Modify the transmission fluid pressure control program in the engine control computer to the corrective specification.
