Automatic Transmission - General Conditions
CAUTION:
Before attempting any repair on an automatic transmission, check for Diagnostic Trouble Codes with the appropriate scan tool.
Transmission malfunctions may be caused by these general conditions:
- Poor engine performance.
- Improper adjustments.
- Hydraulic malfunctions.
- Mechanical malfunctions.
- Electronic malfunctions.
- Transfer case performance (if equipped).
Diagnosis of these problems should always begin by checking the easily accessible variables: fluid level and condition, gearshift cable adjustment (if equipped) and transmission fault codes using the appropriate scan tool. Then perform a road test to determine if the problem has been corrected or if more diagnosis is necessary.
