Fluid Pump
The fluid pump is located between the torque converter and the transaxle case and is driven directly by the torque converter. The pump sucks the fluid through a filter and delivers the fluid to the main pressure regulator valve of the control system. Excess fluid flows back to the pump. The fluid pump fulfills the following functions:
- Generates line pressure
- Delivers fluid under pressure to the torque converter, preventing air bubbles in the fluid
- Induces a flow of fluid through the torque converter in order to eliminate heat.
- Supplies fluid pressure to the hydraulic control system
- Supplies fluid pressure to the shift components
