Diagnostic Notes

Note: Before beginning any diagnosis, familiarize yourself with the Helpful Information section. Helpful Information (Help 1-8)

Note: Before attempting any repair on a 41TE four speed automatic transaxle, check for diagnostic trouble codes with a scan tool. Then use the corresponding Diagnostic Charts.

Malfunctions May Be Caused By These General Conditions:

- Poor Engine Performance

- Improper Adjustments

- Hydraulic Malfunctions

- Mechanical Malfunctions

- Electronic Malfunctions


Preliminary Checks

Note: Always begin diagnosis of these problems by checking the easily accessible variables: fluid level and condition, gearshift cable adjustment. Initial Inspection and Diagnostic Overview

- If a problem is found during the preliminary checks, correct the problem, and determine whether more diagnosis is necessary by performing a road test.

- If the problem exists after the preliminary checks and corrections are completed, perform hydraulic pressure checks.

For Diagnosis Of Faults Follow These Three Basic Steps:


1. Visual Inspection


- A careful and thorough visual inspection may quickly identify the cause of a malfunction and eliminate the need for additional diagnostic procedures.

- Always begin diagnosis of vehicle faults with a visual inspection. If the fault is not resolved by the visual inspection, perform the diagnostic test(s). Initial Inspection and Diagnostic Overview


2. Diagnostic Tests

- To successfully perform diagnostic testing, follow the procedures as presented.

- Always begin diagnostic testing with Test 1A. This will direct you to the specific test(s) that must be performed in response to the specific vehicle fault. Testing and Inspection

- Perform the test for the most current fault.

- Each specific fault is diagnosed by following a specific testing sequence. It is not necessary to perform all of the tests in this book to diagnose an individual fault.


3. Verification Test

- Verify system operation, after the cause of a fault has been found and repaired.

Note: These diagnostic test procedures were designed for use with Chrysler's DRB II diagnostic read-out box. It should be possible to perform the same tests using an equivalent scan tool, by following the manufacturer's instructions.
