A properly working transmission:
- All hydraulic systems must operate with proper pressure.
- The hydraulic control system maintains a constant flow to fluid under pressure to control the shifting of the gear train.
- This facilitates the torque requirements at the drive wheels.
- The fluid flows through the torque converter and through the transmission.
- This lubricates the internal parts, and forces the fluid through a cooler located in the radiator tank (the pressure to keep the clutch from slipping is as much as 2000 pounds. If the 100-pound pressure developed by the pump is applied to a piston with a surface area of 20 square inches, the total force will be 2000 pounds).
- The manual control valve directs control pressure to the holding members and the shift valves.
- The control pressure is directed to two ports at the manual valve, to the primary valve, to the primary throttle valve, to the throttle booster valve, and under the 1-2 accumulator valve.
With time and wear, most transmissions accumulate road dirt, corrosion, and build-ups that stop any of the above processes. The special lubricants in TSC prevent this from happening for the life of your transmission!
