Preliminary Inspection

Transaxle malfunctions may be caused by poor engine performance, improper adjustments, hydraulic malfunctions, mechanical malfunctions or electronic malfunctions. Prior to diagnosing transaxle concerns, always begin by checking fluid level, fluid condition and shift linkage or cable adjustment. Perform road test to determine if problem has been corrected. If problem is still present, several tests must be performed on transaxle. See PERFORMANCE TESTS .

Ensure battery is fully charged. Check engine coolant level. Visually inspect all electrical wiring, looking for chafed, stretched, cut or pinched wiring. Check PCM, sensors and switches for physical damage. Ensure all electrical connections at transaxle switches/sensors, PCM, solenoid assembly and transmission control relay are clean and properly installed.

Repair as necessary. If no problems are found during preliminary inspection, or if driveability concerns still remain, diagnose electronic control system. See TEST EQUIPMENT HOOK-UP  and RETRIEVING DIAGNOSTIC TROUBLE CODES  under SELF-DIAGNOSTIC SYSTEM.
