The oil in your manual transmission is extremely vital to the life of your transmission. Over time it will begin to break down, lose viscosity, and begin to allow excess heat and friction. This kit is the perfect remedy to this problem. Included are 2 quarts of Redline MTL 75w-80 transmission fluid, which features a fully synthetic base for better protection and wear resistance, and Genuine BMW fill and drain plugs.

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 replacement.
