Hydraulic Systems

Fluid Pump
The torque converter is supported in the fluid pump by a needle roller bearing. The fluid pump is driven directly from the engine by the torque converter shell and supplies transmission fluid to the transmission and the hydraulic control unit.

The fluid pump draws in transmission fluid through a filter and delivers it at high pressure to the main pressure valve in the main control valve body unit. The valve adjusts the pressure and returns excess transmission fluid to the fluid pan.

Fluid Filter
All transmission fluid that is picked up from the pan passes through the fluid filter. The filter and its accompanying seal are part of the fluid path from the pan to the fluid pump.
