40/41TE Transaxle General Diagnosis
NOTE:
Before attempting any repair on a 40/41TE four-speed automatic transaxle, check for Diagnostic Trouble Codes (DTC's) using the scan tool. Refer to TRANSMISSION CONTROL MODULE (TCM) - ELECTRICAL DIAGNOSTICS
.
Transaxle malfunctions may be caused by these general conditions:
- Poor engine performance
- Improper adjustments
- Hydraulic malfunctions
- Mechanical malfunctions
- Electronic malfunctions
Diagnosis of these problems should always begin by checking the easily accessible variables: fluid level and condition, gearshift cable adjustment. Then perform a road test to determine if the problem has been corrected or that more diagnosis is necessary. If the problem persists after the preliminary tests and corrections are completed, hydraulic pressure checks should be performed.
