700R4 Valve Body Disassembly - (1988-1992)

I disassemble a 700R4 valve body and show the valve line ups. This later design valve body was produced from late 1987 through 1992. It only takes two check balls—the Drive 3 check ball and the 3rd accumulator check ball (Check balls A & C per the ATSG manual). The low reverse check ball (check ball B) is omitted upon reinstallation, as it is no longer used on auxiliary valve body units.
