# 700-R4 SERVICE REPLACEMENT TRANSMISSION ASSEMBLY PROGRAM

1982 THROUGH 1986 FIREBIRD, BONNEVILLE, GRAND PRIX AND PARISIENNE MODELS

The 700-R4 Service Replacement Transmission Assembly (SRTA) Program has been expanded. Effective November 18, 1985 most 1984 through 1986 model year applications are being added to existing 1982 and 1983 models. These additional SRTA models can be ordered from the local WDDGM Parts Distribution Center (PDC) using the same procedures currently in place for 1982 and 1983 models.

Complete model coverage for 1982 through 1986 model years will become effective in early 1986. At that time, announcements relating to further expansion of the Program will be made via GMPD Bulletins and Parts Catalog updates from WDDGM. A listing of applications is provided in Figure 7 of this bulletin.

Unit replacement through SRTA represents an additional method of service General Motors dealers and Divisions can offer to the customer in instances where major overhaul is necessary. Additional program details are provided in this bulletin as follows:

#### COOLER FLUSHING PROCEDURE

#### IMPORTANT: Transmission oil cooler flushing should be performed whenever a transmission major overhaul or SRTA replacement occurs. It is essential to flush the cooler if fluid contamination is suspected or in any case of pump or torque converter replacement. The service procedure steps for cooler flushing are:

#### INTERNAL

1. Prepare a biodegradable commercial cleaning solution recommended for use with steel, copper, brass, or copper nickel.

2. Remove transmission cooler lines at the transmission and allow cooler to drain.

#### 700-R4 SRTA Program

3. Attach one cooler line to tool J-35944 (available Fall, 1985) to circulate the cleaning solution at a pressure not to exceed 75 psi.

4. Place a filter cloth or screen suitable for trapping foreign material over the remaining cooler line.

5. Attach hot water source and air supply to tool J-35944.

6. Rinse cooler with hot water for 3-5 minutes.

7. Circulate hot water and cleaning solution for 4-5 minutes or until the solution appears clean after having flowed through the cooler.

8. Rinse the cooler with hot water until the water comes out clean, 3-5 minutes.

9. Switch cooler lines and repeat steps 6 through 8.

#### NOTICE: If an abnormal amount of particle contamination is found at the filer cloth or screen during the above flushing procedure, the cooler should be replaced.

10. Blow out the cooler with compressed air to dry.

#### EXTERNAL

1. External cooler surfaces may be steam cleaned and blown off with compressed air.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
