NOTE:
Due to a pump cover casting change in 1985, a 1982 through 1984 THM 700-R4 transmission must be serviced using a complete pump
assembly. Service parts for these earlier model years will be available at a later date.
Seven-vane pump body assemblies, part number 8649950, should be used to service 1985 through 1986 THM 700-R4 transmissions
until current service stock is depleted. The ten-vane pump body assemblies should be used for any 1985 through 1986 model exhibiting
a whine or moan condition and all 1987 THM 700-R4 transmission models.
