Automatic Transmission Service Procedure Changes
Models:
2002 and Prior Passenger Cars and Light Duty Trucks with Automatic Transmissions
This bulletin is being revised to add the 2000-2002 model years. Please discard Corporate Bulletin Number 99-07-30-020 (Section 07 - Transmission).
This bulletin covers the service procedure for cars and light duty trucks equipped with automatic transmissions which are in warranty.
This service procedure allows dealers to repair or replace automatic transmissions based upon the cost of the repair and customer satisfaction. Each repair should be evaluated individually to determine the need for repair or replacement.
^ Transmissions should be repaired whenever the cost of the repair is less than the cost of a Goodwrench Transmission Assembly.
^ A Goodwrench Transmission Assembly should be installed whenever the cost of the repair is greater than an assembly.
^ When two or more repair attempts have not corrected the condition, contact TAO and/or your Area Service Manger (ASM) (DSM in Canada) for further assistance.
^ Only GM Goodwrench DEXRON(R)III automatic transmission fluid is to be used for any warranty service of automatic transmissions.
Cooler Flushing
Cooler flushing and a flow check MUST be performed whenever a transmission is removed for service. It is essential to flush the cooler prior to installation of a Goodwrench Transmission Assembly or when fluid contamination is suspected. Use Kent-Moore tool J 35944-A and solvent J 35944-22 to flush the cooler. Instructions are published in each Service Manual On-Vehicle Service Section. Refer to Corporate Service Bulletin 99-07-30-017 for further details on transmission cooler flushing and flow check.
