A/T - AXOD Valve Body Interchange
TECHNICAL BULLETIN # 093TRANSMISSION: AXOD
SUBJECT: Valve Body Arrangements
APPLICATION: Ford
DATE: FEB 92
Ford made changes to the AXOD valve body arrangements every year of production. The possible combinations for valve body arrangements now total 155,520. Only 6 combinations are correct, that leaves you with 155,514 possible combinations of mismatches. The parts involved are the channel casting, valve body, pump, separator plates & gaskets.
To ID the channel casting, valve body, & pump, look at the rough forge number. (Figure 1) The first digit denotes the decade, the second digit denotes the year of the given decade. In the example below, the E means 1980, the 6 means the 6th year of 1980, which is 1986.
Note
The rough forge system was started in 1940 with the letter "A". "B" = 1950 "C" = 1960 etc.
The rough forge number on the pump is located below the 1-2 capacity modulator valve. On the valve body, the number is under the lock-up solenoid. The channel casting has it's rough forge number below the axle seal. To ID the separater plates, look at the notch code. (Figure 2)
The gaskets are ID'd by colored stripes. There are four possibilities, no stripes, white stripes, yellow stripes and blue stripes. The following information illustrates all of the correct arrangements based on year & engine size.
