Preliminary Inspection: Notes

Visually inspect all electrical wiring, looking for chafed, stretched, cut or pinched wiring. Ensure electrical connectors fit tightly and are not corroded. Inspect air induction system for possible leaks. Ensure vacuum hoses are properly routed and are not pinched or cut. Check for non-factory installed equipment wired into transaxle or PCM harness. Ensure shift linkage is properly adjusted. Check PCM, sensors and actuators for physical damage. Check engine coolant level. Check transmission fluid level and condition.

NOTE: In addition to transmission fault codes, engine-related fault codes may be output during QUICK TEST procedure. These fault codes pertain to engine performance and must be repaired first as engine performance will greatly affect transmission operation. For information and testing procedures of engine-related fault codes and components, see appropriate TESTS W/CODES article in ENGINE PERFORMANCE:
