Service Procedure

1. Remove the valve body cover by following the first seven (7) steps of the "Valve Body Removal" procedures in the "Automatic Transaxle In-Vehicle Repair" section of the "Automatic Transaxle Service Manual."

2. Inspect the upper valve body for the identification symbols shown in step 3 of this campaign service procedure. The outside identification symbol is located to the left of the clutch priority valve bore. The clutch priority valve bore faces the front of the vehicle and can be seen once the valve body cover is removed.

NOTE:





The actual identification symbols are smaller than the examples shown. Identification marks are approximately 1/8" tall. Refer to chart for other identification symbols used on the valve body.

3. Does the identification symbol on the outside of the upper valve body MATCH Symbol MC 104 or MC 105?

a. If the outside identification symbol MATCHES Symbol MC 104 or MC 105, the valve body is not defective. Reinstall the valve body cover following the procedures at the end of "Valve Body Installation." Be sure to use a new pan gasket when reinstalling the valve body cover.

b. If the outside identification symbol DOESN'T MATCH Symbol MC 104 or MC 105, remove the valve body by completing step eight (8) of the "Valve Body Removal" procedure and then go to step four (4) of this procedure.

c. If the outside identification symbol can't be read, proceed to step 4 of this campaign service procedure.

4. With the valve body on the bench, separate the valve body halves by removing the actuator cover to valve body bolts and then remove bolt # 9 which holds the valve body halves together. (Refer to bottom illustration on page TAAT 224 of the 1991-1992 "Transaxle Service Manual" for location of bolt # 9 Also refer to Technical Information Bulletin 92-T-15. Carefully separate the two halves to ensure that the check balls are retained.





5. Inspect the inside identification symbol marked in the valve body passage shown. Does the identification symbol on the upper valve body match Symbol MC 205?

a. If the identification symbol marked inside the upper valve body MATCHES Symbol MC 205, replace the valve body assembly with a new one.

b. If the identification symbol marked inside the upper valve body DOESN'T MATCH Symbol MC 205, the valve body is not defective. Using new spacer place gaskets, and making sure all surfaces are clean, reassemble the valve body and install in vehicle. Be sure to use a new pan gasket when reinstalling the valve body cover. Use "Valve Body Assembly" and "Valve Body Installation" procedures under the "Automatic Transaxle In-Vehicle Repair" section of the "Automatic Transaxle Service Manual." Also refer to Technical Information Bulletin 92-T-15.

c. If the identification symbol marked inside the upper valve body can't be read, replace the valve body assembly with a new one.
