The control system includes: pump, valve block, solenoid valves, hydraulic accumulators, blocking clutches and brakes. The main pressure in the system is created by the pump, it is regulated by the control system depending on the load and vehicle speed, and ensures the operation of the torque converter, lock-up clutches and brakes.
Shift valves control fluid flow to the torque converter and planetary gearbox.
The valve block has three solenoid valves that control gear shifting and torque converter lockup.
