Torque converter oil seal, automatic transmission AL4
Purpose:
The AL4 automatic transmission torque converter seal serves to seal the connection between the torque converter and the transmission housing, preventing transmission fluid leakage.
Design:
The oil seal consists of two parts:
* Metal housing with a working edge that is adjacent to the surface of the torque converter.
* A rubber seal that is pinched between the metal housing and the gearbox housing.
Materials:
* Metal body: aluminum or steel
* Rubber seal: oil resistant rubber such as nitrile or fluoroelastomer
Installation:
The torque converter oil seal is installed in the corresponding groove on the gearbox housing. The rubber seal is lubricated with transmission fluid to ensure a seal.
Replacement:
Replacing the torque converter seal of an AL4 automatic transmission is usually required if it fails, which can lead to transmission fluid leakage.
Symptoms of a faulty torque converter oil seal:
* Leakage of transmission fluid from the area between the torque converter and the gearbox.
* Drop in transmission fluid level in the gearbox.
* Difficulty shifting gears.
* Gear slippage.
Important: Replacing the AL4 automatic transmission torque converter oil seal should be performed by a qualified specialist using special tools and equipment.
