Hot fluid from the transmission lines travels to this cooler, where air or engine coolant dissipates the excess heat before the fluid is returned to the pan. The transmission oil go inside the converter lubricates its internal bearings and turbine fins, while also transferring engine power to the transmission input shaft.
Transmission Oil Pressure Pathway From Pump To Planetary Gearsets
Here, the fluid pressure engages or disengages these bands and clutches to achieve the correct gear ratio. This final stage of lubrication protects the components that handle the highest stresses and loads within the entire system.
The Transmission Pan and Sump The journey begins in the transmission pan, a large reservoir bolted to the bottom of the transmission housing. Pump Pressurization and Initial Flow When you start the engine, the crankshaft’s rotation drives the transmission pump, usually located inside the pan or connected to it.
Transmission Oil Pressure Pathway Inside the System
The pan is sealed with a gasket or a drain plug, and it is crucial to maintain the correct fluid level here, as this is the primary supply for the system. These intricate assemblies contain sun gears, planet gears, and ring gears that provide the various gear ratios.
