Overhaul of automatic transmission in block with drive axle [Toyota Highlander XU20]

In the event of a malfunction, before attempting repairs, it is necessary to determine whether the problem is electrical, mechanical or hydraulic in nature. Diagnostics require specialized knowledge of the operation and design of the gearbox, as well as specialized testing equipment. Major repairs are not covered in detail in this manual. Therefore, if you have problems with an automatic transmission, it is strongly recommended that you contact a dealer or other specialized service station.

Do not remove the transmission from the vehicle for possible repairs until professional diagnostics have been performed using the proper equipment. Most tests can be performed without removing the transmission from the vehicle.
