General information
1. The hydraulic control system of the gearbox consists of the following units:
- 1) Oil pump: Generates hydraulic pressure.
- 2) Regulator: Maintains hydraulic pressure at a constant level.
- 3) Solenoid valves: convert TCM signals into hydraulic pressure.
- 4) Pressure control valve: controls the hydraulic pressure acting on the clutches and brakes according to the hydraulic pressure from the solenoid valves.
- 5) Individual valves: transfer pipeline pressure to various oil lines.
These elements are located in the valve body.
2. Independent electronic control of the hydraulic pressure of the clutches and brakes by switching solenoid valves ensures smooth and very sensitive gear shifts.
3. The oil filter is installed in only one place. Also, the use of a newly developed transmission fluid (ATF) ensures significantly longer transmission life.
4. To prevent leakage of ATF from the valve body, clutches and brakes when the engine is off, the valve drain channels are connected to a single drain channel located at the top of the body, and a ball valve is installed at the end of the water drain line.
5. In the event of an electronic malfunction of the control system, the commutator valve and the initial position of the valves allow movement in 3rd gear or reverse gear.
