1. Transmission housing: The transmission housing is the main component that holds the transmission gears, shafts, and other parts. Transmission oil is filled into the housing through the designated filler plug or dipstick tube.
2. Oil pump: The oil pump is responsible for circulating the transmission oil throughout the transmission system. It draws the oil from the bottom of the transmission housing and pumps it through various channels and passages.
3. Transmission channels and passages: The transmission housing has internal channels and passages through which the transmission oil flows. These channels allow the oil to reach all the moving parts within the transmission.
4. Gears: Transmission oil lubricates the gear teeth, reducing friction and wear during gear engagements and providing efficient power transfer.
5. Bearings: Transmission oil also lubricates the bearings that support the shafts and other rotating parts within the transmission, minimizing friction and preventing premature wear.
6. Clutch plates (in some automatic transmissions): In automatic transmissions, there are clutch plates that engage and disengage to change gears. Transmission oil helps keep these clutch plates cool and lubricated to ensure smooth shifting.
7. Control unit: In automatic transmissions, there's a hydraulic control unit or valve body that controls the gear changes. Transmission oil helps actuate the valves and pistons within this control unit, ensuring proper shifting and operation of the transmission.
The specific location of the transmission oil filler plug or dipstick may vary depending on the vehicle make, model, and type of transmission. It's important to refer to the vehicle's owner's manual or consult a qualified mechanic for accurate information on checking and adding transmission oil.
