Transmission External Sealing
The pump housing has a cassette-type seal for the torque converter impeller hub that is pressed into the pump and bonds itself to the torque converter hub surface during operation. The pump assembly uses a large rubber seal that seals the pump housing to the transmission case. The pump body uses a rubber seal that seals the pump body to the pump housing.
The manual control shaft has a lip seal that is pressed in the transmission case.
The transmission fluid pan and the PTO cover use a reusable gasket.
The fixed flange applications use a lip-type seal that seals the transmission case to the output shaft nut. There are also 2 plugs in the back of the transmission case that have a seal that is part of the plug.
The slip yoke application uses an O-ring seal that seals the extension housing to the transmission case and a lip-type seal that seals the extension housing to the driveshaft.
On the left side of the transmission case, there is a line pressure tap plug with a seal that is part of the plug.
The large transmission case housing plug provides access to the park pawl shaft and has an O-ring seal.
The internal wiring harness bulkhead connector has an O-ring seal for the transmission case bore.
The transmission fluid filler tube uses an O-ring seal.
The transmission fluid cooler tubes use 4 O-ring seals to seal the tubes to the transmission case.
The transmission fluid drain plug has a bonded rubber seal.
