What are the effects of overfilling manual transmission fluid?
1 Answers
Overfilling manual transmission fluid can increase the internal operating resistance of the transmission and even cause abnormal oil leakage. High oil pressure may lead to seal leaks, and excess fluid can overflow through the vent hole. If the transmission fluid is overfilled, it is recommended to adjust the fluid level promptly. Manual transmission fluid is a type of automotive gear oil used for lubricating gears in components such as the transmission, front and rear axle differentials, and transfer case. Automatic transmission fluid (ATF) is used in automatic transmissions (automatic vehicles). Note that automotive gear oil should not be confused with industrial gear oil, as the two types cannot be mixed or substituted for each other. Similarly, manual transmission fluid and automatic transmission fluid should not be mixed or substituted for each other.
