WARNING: This page is about a different car, the 2013 Dodge Avenger and 2013 Chrysler 200. However, it is still accessible from the selected car via links, so may be relevant.

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 the appropriate Transmission Diagnostic Procedures Information.

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.
