New upper and lower main control valve body gaskets have been released for service. The new gasket has an additional slot, which reduces the chance for contamination of the 3-4 shift valve (refer to Figures 11 and 12). The new gaskets can be used on all AOD main control valve bodies produced for the 1980-86 model years.


Old upper and lower main control valve body gaskets (EOAZ-7D100-B and EOAZ-7C155-A) may still be used on certain applications. To identify the correct application, the middle letter of the main control valve body's three-letter I.D. code is necessary. Refer to the following service usage chart for the correct gasket applications.
