Automatic transmission cooling system Mazda CX-7
The Mazda CX-7 automatic transmission cooling system is designed to remove heat generated in the gearbox during operation. This is necessary to prevent overheating and ensure reliable operation of the gearbox.
The Mazda CX-7 automatic transmission cooling system consists of the following components:
1. Automatic transmission heat exchanger:
*Located in the engine cooling radiator.
* Transfers heat from the automatic transmission to the engine coolant.
2. Coolant:
* Circulates through the automatic transmission heat exchanger and the engine radiator.
* Absorbs heat from the automatic transmission and transfers it to the radiator.
3. Engine cooling radiator:
*Located at the front of the vehicle.
* Cools the coolant by dissipating heat to the environment.
4. Automatic transmission cooling pipes:
* Connect the automatic transmission heat exchanger to the engine cooling radiator.
* Coolant circulates through them.
5. Automatic transmission temperature sensor:
* Monitors automatic transmission temperature.
* Sends a signal to the automatic transmission control module (TCM).
6. Automatic transmission control unit (TCM):
* Controls the operation of the automatic transmission cooling system.
* Turns on and off the circulation of coolant through the automatic transmission heat exchanger depending on the temperature of the automatic transmission.
How the automatic transmission cooling system works:
When the transmission temperature reaches the set point, the TCM circulates coolant through the transmission heat exchanger. Heat from the automatic transmission is transferred to the coolant and removed through the engine cooling radiator. As the coolant flows through the radiator, it is cooled by the air entering through the grille. The cooled coolant is then returned to the automatic transmission heat exchanger and repeats the cycle.
