How long is the warranty period for a transmission replacement?

[VanCharlotte]

The engine oil added to the engine has a warranty period of only one year. This is because the working environment of engine oil in the crankcase is quite harsh. High-temperature exhaust gases, gasoline, water vapor, sulfides, and other substances from the engine combustion chamber can infiltrate the oil through piston ring blow-by, causing the oil to oxidize and deteriorate rapidly under high temperature and pressure. This, in turn, shortens the service life of the engine oil. Therefore, the service cycle of transmission fluid is relatively long, and there is essentially no expiration date. However, after prolonged use, transmission fluid does need to be replaced, typically around 60,000 to 70,000 kilometers.
