During March 1983, a revised 3-4/4-3 shift pattern was incorporated as a running change for all AOD transmissions. (Refer to TSB 83-10-11, dated May
17, 1983.) Compared to the old design, the new pattern has a later 3-4 upshift and a more sensitive 4-3 downshift. The shift schedule was revised on May
20, 1983 to reduce the 3-4 shift speed and to make the 4-3 downshift less sensitive.
If a 1983 transmission built during the March-April-May period result in a customer concern, it may be updated or revised to current production levels.
Verify the transmission build date by the model identification tag attached to the right hand extension housing case bolt. Refer to the Shop Manual
Section 17-20 for the location of the build date on the identification tag. First check the throttle linkage adjustment since this alone could be causing the
concern. Also, the car should have at least 500 miles (800 km) on the odometer before proceeding with the update. The models involved and the
updating procedure are described below.

1.
Check the throttle linkage adjustment. If it is not to specification, then adjust the linkage and reevaluate the car. If the problem persists, and the
vehicle has been driven more than 500 miles (800 km), proceed with the update.
2.
Remove the transmission oil pan and verify that the main controls are stamped with the 1983 running change ID code. If so, then continue.
3.
Remove main control assembly from transmission. Refer to the main control valve body removal procedure in Section 17-20 of the Shop Manual.
Disassemble the main control by removing the twelve main control assembly bolts and lifting off the separating plate and three circular reinforcing
plates. Refer to the main control valve body disassembly procedure in Section 17-20 of the Shop Manual.
