Transfer case
The
Transfer Case is a gearbox that attaches to the output shaft of the
transmission through a splined input at the transfer case. Torque from
the transmission is transferred to the rear driveshaft through the
transfer case mainshaft. When torque to the front driveshaft is required
it is transferred through a multi plate wet clutch and chain drive
arrangement to the front output shaft of the transfer case.
