    Caution: To reduce the possibility of personal injury or transmission damage, make sure, when doing the next step, that all of the bolts for the support fixture are installed as shown, and that the bolts are tightened to 11 N·m (98 lb in).

    Important: J 41230 should be updated using J 41230-TEM due to transmission mounting changes.

  1. Install the J 41230 transmission support fixture onto the transmission.

Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

  4. Tighten
    Tighten the support fixture bolts to 11 N·m (8 lb ft).
