BMW Drivetrain Parts for BMW 3 Series E46 (1999-2005)

Clear BMW chassis

Building your perfect BMW is more than just adding horsepower and stiff suspension. Your drivetrain needs attention in order to deliver power effectively. Most BMWs feature comfortable clutch discs, heavy flywheels, long shifter throws, and open differentials. The drivetrain transmits power to the wheels, but can also be a source of power loss when it is designed for comfort rather than performance. Everything on this page will help you improve your power delivery and driving experience by providing custom Limited Slip Differentials, Short Shift Conversions, Performance Clutch Discs, Lightweight Flywheels, and anything else your BMW needs to be the perfect driving experience.

This replacement flex disc (aka: the guibo) is a vibration dampener mounted on the back of the transmission which connects to the driveshaft. When it has worn, it produces a terrible vibration throughout the car. It's especially noticeable at low speeds and when starting from a standstill. Oil leaking from the back of the transmission will significantly reduce its life. From 1974 to 2019, Bavarian Autosport was one of the premier vendors for BMW and MINI auto parts. We are happy to preserve the Bav Auto legacy by continuing to carry their high-quality products into the future. All Bav Auto parts will remain unchanged in design and sourced from the same OEM suppliers to ensure long-lasting reliability. We trust these parts, accessories, and upgrades so confidently that we back every Bavarian Autosport branded component with a 2-year warranty.

This Bav Auto replacement flex disc (aka: the guibo) is a vibration dampener mounted on the back of the transmission which connects to the driveshaft. When it has worn, it can produce knocking sounds and a terrible vibration throughout the car. It's especially noticeable at low speeds and when starting from a standstill. Oil leaking from the back of the transmission will significantly reduce its life. This can also be used as an upgrade on the E30 M3. It has much more rubber in between the bolt holes which makes it last longer. This is 5mm thicker than the stock E30 flex disc so adjustment of the 2-piece driveshaft may be required. The original flex disc bolts can be re-used.

This is the coolant temperature sensor used in many BMW models from the late-1990s to the mid-2010s. The engine computer relies on the coolant temp to set the fuel mapping for the engine. As the car warms up the computer changes the fuel mixture. If your car is running a bit rich (too much fuel) it could be because this sensor is failing and not sending the correct info to the computer. This sensor is located in a variety of places depending on the engine. But it's one of those easy replacement items 'while you're in there' when doing a water pump or thermostat replacement. From 1974 to 2019, Bavarian Autosport was one of the premier vendors for BMW and MINI auto parts. We are happy to preserve the Bav Auto legacy by continuing to carry their high-quality products into the future. All Bav Auto parts will remain unchanged in design and sourced from the same OEM suppliers to ensure long-lasting reliability. We trust these parts, accessories, and upgrades so confidently that we back every Bavarian Autosport branded component with a 2-year warranty.
