Transaxle Removal & Installation


Make sure the wheels of the vehicle are in the straight ahead position and the steering column in the LOCK position before disconnecting the steering column or intermediate shaft from the steering gear. Failure to do so will cause the SIR coil assembly to become uncentered, which may cause damage to the coil assembly.

  1. Lock the steering column by installing tool J-42640 into the underside of the steering column.
  3. Remove or disconnect the following:

    Negative battery cable
    Air cleaner
    Range selector cable from the range selector lever
    Range selector cable with the bracket from the transmission case
    Transaxle electrical connector
    Wiring harness from the wiring harness retainer
    Ground cable bolt from the transaxle

  5. Install an engine support fixture.
    Failure to disconnect the intermediate shaft from the rack and pinion steering gear stub shaft can result in damage to the steering gear or to the intermediate shaft. This damage may cause loss of steering control, which could result in an accident and possible personal injury.
