Over the life of a vehicle, the transmission can often be overlooked when performing routine maintenance. If left unserviced, the automatic transmission fluid will break down, causing the valve body and filter to become contaminated with deposits and sludge. This will lead to poor shifting, slipping, and ultimately, transmission failure. Kit Includes: Automatic transmission filter with associated hardware Oil pan gasket Drain plug with sealing washer Fill plug with sealing washer 7 quarts Redline D4 automatic transmission fluid

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.
