Verify proper transmission function as outlined in the "Diagnosis and Testing" Section (07-01A) of the Service Manual. Service as required. If concern still exists, refer to the following procedure for service details.
SERVICE PROCEDURE
1. Examine vehicle for aftermarket modifications and verify proper installation. Service as required. If no problem is found, go to Step 2.
2. Refer to the "Driveline Angle Check" located in the Service Manual, Section 05-00, to verify driveline angles are within specification and service as required. If no problem is found, go to Step 3.
3. Perform "Transmission Cooler Flow Test" found in "Diagnosis and Testing", Section 07-01 A of the Service Manual, to verify no restriction of fluid flow in the cooler. Service as required. If no problem is found, go to Step 4.
