What is the method for sealing the transmission?
2 Answers
The method for dealing with oil leakage in a car's transmission is to apply sealant to the leakage point, which involves cleaning the surface of oil sludge and then applying sealant. It cannot be ruled out that some transmissions may develop seepage issues. If traces of fluid flow are found on the oil-stained surface, the car owner should promptly take the vehicle to a shop for inspection. If there is damage to the joint surface of the transmission case, an appropriately thicker paper gasket should be added at the damaged area. If the transmission cover screws are loose, they should be tightened promptly.
The transmission seal is primarily designed to prevent oil leaks and protect internal components. As an automotive technician like me, we typically use rubber oil seals for the output or input shaft areas. During installation, it's crucial to clean the surface thoroughly to ensure there's no oil residue or scratches, then apply a bit of specialized sealant to guarantee a snug fit. When replacing a new oil seal, carefully align it and press it in by hand—avoid using tools to hammer it in, as this can easily deform the seal and cause leaks. Additionally, RTV silicone is commonly used for oil pan sealing; apply a thin layer, wait a few minutes for it to cure, and then tighten the bolts for a long-lasting seal. Regularly check the oil level—if it's low, inspect the seals immediately, as oil leaks can damage the transmission and increase repair costs.
