Nissan Transmission Cooling System
Target:
The transmission cooling system is designed to dissipate the heat generated when the transmission operates. Heat can cause premature wear and failure of transmission components.
Components:
* Heat exchanger: a tubular coil that is located inside the engine radiator or separately.
*Engine coolant: circulates through the heat exchanger, absorbing heat from the transmission fluid.
* Cooling lines: connect the gearbox to the heat exchanger.
*Transmission Pump: Pumps transmission fluid through the cooling system.
Job:
1. The transmission pump circulates transmission fluid through the transmission, collecting heat from components including gears, bearings and clutches.
2. Hot transmission fluid enters the heat exchanger.
3. Engine coolant circulates through the heat exchanger in the opposite direction.
4. Heat is transferred from the transmission fluid to the engine coolant.
5. The cooled transmission fluid is returned to the gearbox, and the cycle is repeated.
Advantages:
* Extends transmission life by reducing wear and stress.
* Improves gear shift performance by reducing transmission fluid viscosity at high temperatures.
* Improves transmission efficiency by reducing transmission losses caused by friction.
Service:
* Check the level and condition of the transmission fluid regularly.
* Replace transmission fluid and filter promptly.
* Clean the heat exchanger of any debris or deposits.
* Periodically check the cooling lines and their connections for leaks.
