BMW 3-Series Transmission Seals & Gaskets

An internal combustion engine is an energy transforming machine that can develop a colossal amount of mechanical power and torque. This energy, however, is available only within a pretty narrow range of RPM, which is why there is always a transmission that allows the engine to stay in that range without compromising on vehicle’s usability or speed. Inside, the transmission is a set of gears that experience the action of great forces resulting in their mechanical wear and heating. In order to decrease unfavorable effects caused by these two factors, the transmission case is filled with a lubricant (ATF for automatic gearboxes).

In order to carry out its duties most efficiently, oil must have excellent penetration ability, which it actually features. And that is the issue when it comes to a deteriorated seal, since this property of oil results in leaks through even the tiniest chinks. Therefore, the replacement of old, worn seals and gaskets is an important deed that you shouldn’t hesitate with. As these parts don't cost much, it's wise to buy nothing but the highest-quality products, especially for the BMW 3-Series. And you will find a lot of them in our BMW 3-Series transmission seals & gaskets collection.
