Replacement Part

Caution

•  If the automatic transaxle has been replaced, perform TCM configuration. (See TCM CONFIGURATION [GW6A-EL, GW6AX-EL].)

•  If the automatic transaxle has been replaced, perform initial learning. (See INITIAL LEARNING [GW6A-EL, GW6AX-EL].)

•  Performing the following procedures could cause an open circuit in the front ABS wheel-speed sensor wiring harness if it is pulled by mistake. Before servicing, disconnect the front ABS wheel-speed sensor and set it aside so that the wiring harness will not be pulled by mistake.

•  Secure the steering wheel using tape or a cable to prevent the steering shaft from rotating after disconnecting the steering shaft. If the steering wheel rotates after the steering shaft and the steering gear and linkage are disconnected, the internal parts of the clock spring could be damaged.
