Bronco L6-300 4.9L VIN Y 1-bbl (1983)
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.
