Coast Clutch Housing Differences - ATSG FORD 4R100 Manual

Coast Clutch Housing Changes
The coast clutch housing is model sensitive and there
are three different versions, as shown above. The
"Cast-Iron" coast clutch housing is the same as the
E4OD housing. When the "Stamped Steel" version
was introduced, it affected other parts in the
transmission, like the coast clutch steel plates and the
overdrive friction plates, as shown above.

The sealing ring locations on the oil pump stator
were also affected, which makes the oil pump stator
shaft model sensitive, depending on which coast
clutch housing you have, but we will discuss this in
the oil pump section of this manaul.
The rebuild procedure on all 3 coast clutch housings
is very similar and begins on Page 90.
