Replacement

Note. When replacing the Transaxle Control Module (TCM), the vehicle equipped with immobilizer must be performed the procedure as below. [In the case of installing used TCM] Perform "TCM neutralization mode" procedure with GDS. Insert the key and turn it to the IGN ON and OFF position. Then the TCM key register process is completed automatically. [In the case of installing new TCM]- Insert the key and turn it to the IGN ON and OFF position. Then the TCM key register process is completed automatically.

Removal

Note. Replacing an on/off solenoid valve (SS-A, SS-B) does not require additional hydraulic pressure adjustment; however, the hydraulic pressure will need to be adjusted after replacing the VFS solenoid valve. If replacing the VFS solenoid valve; also replace the valve body assembly. (Refer to " VALVE BODY ")
