Obtain the thickness of transfer driven gear shim using the following formula to select one to three transfer driven gear shims.
T mm = A - B - (0.05 - 0.25)

[T in = A - B - (0.002 - 0.01)]

T: Transfer driven gear shim thickness

A: Height from the ST end face to the transfer clutch thrust bearing catch surface

B: Height from the mating surface of the transmission case to the end of the ST 0.05 - 0.25 mm (0.002 - 0.01 in): Clearance
