OIL PUMP
DESCRIPTION
The oil pump is located in the pump housing inside
the bell housing of the transaxle case (Fig. 266). The
oil pump consists of an inner and outer gear, a hous-
ing, and a cover that also serves as the reaction shaft
support.

OPERATION
As the torque converter rotates, the converter hub
rotates the inner and outer gears. As the gears
rotate,
the
clearance
increases in the crescent area, and creates a suction
at the inlet side of the pump. This suction draws
fluid through the pump inlet from the oil pan. As the
clearance between the gear teeth in the crescent area
decreases, it forces pressurized fluid into the pump
outlet and to the valve body.
STANDARD PROCEDURE - OIL PUMP VOLUME
CHECK
Measuring oil pump output volume will determine
if sufficient flow to the transmission oil cooler exists,
and whether or not an internal transmission failure
is present.
Verify that transmission fluid is at the proper
level. If adding fluid is necessary, fill to the proper
level with Mopar
