Visual Inspection

This inspection will identify malfunctions to the vehicle operating system that may affect diagnosis.
- Vehicle modification
- Electronic add-on items
- Air conditioning
- Generator (alternator)
- Engine turbo
- Cellular telephone
- Cruise control
- CB radio
- Linear booster
- Backup alarm signal
- Computer

- Leaks
- Proper linkage adjustments

These items, if not installed properly, will affect powertrain control module or transmission function. Pay particular attention to add-on wiring splices in the powertrain control module harness or transmission wiring harness, abnormal tire size, or axle ratio changes.

After a road test, with the vehicle warm and before disturbing any connectors, perform the Quick Test using Rotunda New Generation STAR (NGS) Tester 007-00500 or equivalent.

Refer to all Technical Service Bulletins which pertain to the transmission concern and follow the procedures as outlined.
