Discussion:

Automatic transmission equipped vehicles now include quick connector fittings in the transmission cooler lines. If the transmission requires service, the connectors can be disconnected using either of the following two procedures. Proper reconnect procedures are also provided.  

NOTE: SOME 1997 VEHICLES ARE NOT EQUIPPED WITH EXTERNAL RETAINER TABS. THESE VEHICLES MUST USE THE TOOL REMOVAL PROCEDURE TO DISCONNECT TRANSMISSION COOLER LINES.

Removal Procedure:

This bulletin outlines the two methods of disconnecting the quick connectors on automatic transmission cooler lines, and provides the proper reconnect procedures.

1.    Use a rag or soft brush to wipe the external surface of the connector and male line to remove loose dirt and road salt. Twist connector around the line or flush the joint with a mild soap penetrant such as Mopar General Purpose Lube MP-50 (PIN 4549626), to remove stubborn crusted contaminants.

2.    Use an air nozzle to blow out accumulated dirt and road salt from the retainer area of the connector.  

HAND REMOVAL PROCEDURE:

1.    Holding the line as shown, grasp connector body with fingers touching the retainer tabs (Figure 1).

 

 2.    Push line into connector until line stops (Figure 2).

3.    Squeeze retainer tabs together until both tabs contact line (Figure 3).

4.    Pull line out of the connector with other hand while retainer tabs are squeezed together (Figure 4).

TOOL REMOVAL PROCEDURE:

1.    Select the proper tool. For vehicles equipped with the 5.9L Cummins Diesel or the S.OL gas engine (1/2" cooler lines), use Miller Special Tool 6931. All other vehicles use a 3/8" cooler line and require Miller Special Tool 6935.

2.    Unlock the small tab on side of tool and open (Figure 5).

3.    Wrap tool around line with smooth round end facing the connector (Figure 6).

 

4.    Close removal tool and lock tab. Push removal tool up to connector (Figure 7).

5.    Push removal tool into connector. Tool will push out retainer legs, pull connector over line bead (Figure 8).

 

6.    Pull line connector while holding onto line with one hand and the connector with the other (Figure 9).

RECONNECT PROCEDURE:

1.    After performing the service that required the line to be disconnected, wipe the line end with a clean rag.

2.    Check the line surfaces for burrs on existing or replacement parts.

3.    Apply a coating of clean transmission fluid over the entire male line end surface up to the bead.

4.    Push the line into the connector until the retainer seats and a click is heard. Pull back on the line to ensure that the connector is locked in place (15-30 lbs.). Do not rely only on the audible click to confirm that a secure connection has been made.

5.    Start the engine and check the connector for fluid leaks.
