SERVICE INFORMATION:
THE 1992 HYDRA-MATIC 4L80-E/4L80-EHD GOODWRENCH TRANSMISSION PROGRAM BEGAN ON SEPTEMBER 1, 1991. GOODWRENCH TRANSMISSION MODELS CAN BE ORDERED FOR ALL 1991 THROUGH 1994 HYDRA-MATIC 4L80-E/4L80-EHD MODEL APPLICATIONS FROM YOUR LOCAL GENERAL MOTORS SERVICE PARTS OPERATION (GMSPO) DISTRIBUTION CENTER. THIS BULLETIN CONTAINS A LISTING OF THE GOODWRENCH TRANSMISSION MODELS AND PART NUMBERS CURRENTLY AVAILABLE TO SERVICE 1991 THROUGH 1994 HYDRA-MATIC 4L80-E/4L80-EHD TRANSMISSIONS.
GOODWRENCH TRANSMISSION ADVANTAGES: A GOODWRENCH TRANSMISSION IS THE PRODUCT OF A HIGHLY SUCCESSFUL, CUSTOMER SATISFACTION DRIVEN PROGRAM PROVIDING THE TECHNICIAN WITH A SERVICE ALTERNATIVE WHEN ADDRESSING DIAGNOSTIC AND OVERHAUL CONCERNS.
ALL GOODWRENCH TRANSMISSIONS ARE DESIGNED AND REMANUFACTURED TO CURRENT ENGINEERING SPECIFICATIONS AND ARE OFTEN LESS COSTLY THAN A MAJOR OVERHAUL.
GMSPO PARTS DISTRIBUTION CENTERS ARE COMMITTED TO 48 HOUR MAXIMUM DELIVERY TIME FOR ALL GOODWRENCH TRANSMISSION MODELS, WITH NO VIP CHARGES.
IN THE INTEREST OF CUSTOMER SATISFACTION, GOODWRENCH TRANSMISSIONS SHOULD BE CONSIDERED WHEN THE PROJECTED COST OF REPAIR EXCEEDS THE COST OF A GOODWRENCH TRANSMISSION ASSEMBLY.
COOLER FLUSHING MUST BE PERFORMED WHENEVER A TRANSMISSION/TRANSAXLE IS REMOVED FOR SERVICE. IT IS ESSENTIAL TO FLUSH THE COOLER BEFORE TRANSMISSION INSTALLATION, MAJOR OVERHAUL, IN ANY CASE OF PUMP OR TORQUE CONVERTER REPLACEMENT, OR WHEN FLUID CONTAMINATION IS SUSPECTED.
NOTE: 1994 4L80-E/4L80-EHD GOODWRENCH TRANSMISSIONS CANNOT BE USED TO SERVICE ANY 1993 OR PRIOR APPLICATIONS.
PARTS INFORMATION:
NOTE: GMC TRUCK DEALERS SHOULD REFER TO CORPORATE BULLETIN #367106, AUTOMATIC TRANSMISSION SERVICE PROCEDURE CHANGES PUBLISHED IN DECEMBER, 1993 FOR CORRECT SERVICE PROCEDURES ON REPAIRS UNDER WARRANTY.
