Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. 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. Install the lower transaxle bolt (6) and stud (1).

Tighten

22. Install the air cleaner assembly. Refer to Air Cleaner Assembly Replacement in Engine Controls-3.4L.



23. Install the coolant recovery bottle.
24. Inspect and adjust the transaxle fluid level as needed. Refer to the following information.

•	Transmission Fluid Check

•	Fluid and Lubricant Recommendations

•	Approximate Fluid Capacities

Important: It is recommended that the transmission adaptive pressure (TAP) information be reset.

Resetting the TAP values using a scan tool will erase all learned values in all cells. As a result, the ECM, PCM or TCM will need to relearn the TAP values. Transmission performance may be affected as new TAP values are learned.
25. Reset the TAP values. Refer to Transmission Adaptive Functions .
