low/reverse (rear) bands which, along with the over-

running clutch and overdrive clutch, serve as the
holding components. The driving and holding compo-

nents combine to select the necessary planetary gear

components, in the front, rear, or overdrive planetary

gear set, transfer the engine power from the input

shaft through to the output shaft.

The valve body is mounted to the lower side of the
transmission and contains the valves to control pres-
sure regulation, fluid flow control, and clutch/band
application. The oil pump is mounted at the front of
the transmission and is driven by the torque con-
verter hub. The pump supplies the oil pressure nec-
essary for clutch/band actuation and transmission
lubrication.
