TRANSAXLE GENERAL DIAGNOSIS

CAUTION: Before attempting any repair on a Electronic Automatic Transaxle (EATX), check for fault codes with the DRB II. Always use the Powertrain Diagnostic Test Procedure Manual.

Ä

Transaxle malfunctions may be caused by these general conditions:

²Poor engine performance

²Improper adjustments

²Hydraulic malfunctions

²Mechanical malfunctions

²Electronic 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 exists after the preliminary tests and corrections are completed, hydraulic pressure checks should be performed.
