SERVICE INFORMATION
Whenever an automatic transmission (A/T) is repaired, overhauled, or replaced, the A/T oil cooler mounted in the radiator must be inspected and
cleaned.
^
Metal debris and friction material, if present, can become trapped in the A/T oil cooler and may build up as transmission fluid enters the Cooler Inlet.
^
This debris can contaminate the newly serviced transmission.
^
In severe cases this debris can block or restrict the flow of transmission fluid oil. In either case, failure of the newly serviced A/T may result.
It will be necessary to back flush the cooler through the Cooler Outlet in order to flush out any built up debris.
^
The location of the Cooler Inlet and Outlet Hoses described in this bulletin determines the direction of transmission fluid flow through the cooler.
^
The Inlet and Outlet position varies from model to model, and you must identify the location of the Cooler Inlet and Outlet to successfully perform
the cleaning procedure.
Refer to the "SERVICE PROCEDURE" Workflow to determine the procedure for a particular vehicle.
^
Use Charts A and B to establish the correct Cooler Inlet and Outlet location for the vehicle you are servicing.
^
Then perform the Cleaning, Diagnosis, and Inspection as instructed.
