Automatic transmission cooling system Mitsubishi Pajero 2
The automatic transmission cooling system in the Mitsubishi Pajero 2 is designed to remove excess heat from the gearbox, preventing it from overheating.
Automatic transmission cooling system components:
*Main Radiator: Located in front of the engine oil cooler and designed to remove heat from the transmission fluid.
* Oil cooler: located behind the main radiator and is designed to provide additional cooling to the transmission fluid.
* Automatic transmission thermostat: regulates the flow of transmission fluid through the radiators, opening and closing at specified temperatures.
* Tubes and Hoses: Transport transmission fluid to and from the radiators and thermostat.
* Automatic transmission pump: circulates transmission fluid throughout the system.
Working principle:
1. When the engine is running, transmission fluid circulates through the automatic transmission pump.
2. Hot fluid passes through the thermostat and, if its temperature exceeds the set value, is sent to the main radiator.
3. In the main radiator, the liquid is cooled by the air flow passing through it.
4. The cooled liquid returns to the thermostat and is again sent to the automatic transmission radiator, if necessary.
5. An oil cooler provides additional cooling when the main radiator is not sufficient to dissipate heat.
Maintenance and faults:
* Check the level and condition of the transmission fluid regularly.
* Replace transmission fluid and filter according to manufacturer’s recommendations.
* Inspect radiators and pipes for leaks or blockages.
* Thermostat malfunctions can lead to overheating or insufficient cooling of the automatic transmission.
Signs of a faulty automatic transmission cooling system:
* Overheating of the automatic transmission, manifested in the form of a burning smell or slipping of gears.
*Low transmission fluid level.
* Leaks or blockages in radiators or pipes.
* Thermostat malfunctions.
