BMW Transmission Parts

Looking for parts for your BMW automatic transmission or manual transmission? You'll find many of the parts available to service your BMW's transmission here. While internal transmission servicing and rebuilding should be done by professionals, there are a lot of things on the outside of the transmission that you can service or replace yourself. These include gearbox seals, o-rings, gaskets, automatic transmission filters, backup light switches, mounting bolts, flanges, collar nuts, screw plugs, Mechatronics, and more.

Everyone knows that heat is the enemy of your automatic transmission. And everyone knows that higher power levels generate more transmission fluid heat. Now you can extend the life of your automatic transmission by installing the new Burger Motorsports High Capacity Trans Cooler kit. This unique plug-and-play kit replaces your factory coolant to trans fluid heat exchanger with a high-capacity fender-mounted air-to-trans fluid radiator. Includes all mounting hardware, lines, and coolant caps required for installation. Installs inside the driverside fender providing ample airflow over the large cooling core via existing openings. The result is dramatically reduced transmission temperature and extended transmission life. This kit is strongly suggested for any BMW E chassis automatic running larger than factory turbos. The thermostat maintains the oil exiting the transmission at the rated minimum temperature in most conditions. Without a thermostat, the transmission fluid coolers are likely to over-cool the fluid, delaying transmission warm-up and performing the critical function of bypassing the cooler until the oil has reached its minimum operating temperature. FEATURES AND BENEFITS Dissipates excess transmission fluid heat Reduces transmission fluid temperature Increases transmission life when racing Increases transmission oil capacity Fitment: 2008-2013 E81 E82 E87 Coupe and Hatchback 135i 2008-2013 E88 Convertible 135i Compatible with both RHD and LHD vehicles. Not compatible with manual transmissions.

Like the DCT oil pan, the plastic OEM hydraulics cover is prone to fatiguing from heat cycling; not ideal considering the important parts that reside behind it. And also like it's oil pan sibling, the Fall-Line hydraulics cover uses a bespoke Viton O-Ring that resides within a clever internal channel. Viton O-Rings, due to their exceptional resistance to temperature extremes (-20°F to 400°F operating temp) and low gas permeability, have incredible aging characteristics and therefore eliminate the need for regular replacement.

The Ultimate DCT Track Package. Period! Fall-Line has designed an incredible 6061-T6 aluminum oil pan and matching hydraulics cover for DCT cars. The plastic OEM parts are prone to failure from heat-cycling and use a brittle gasket that requires replacement over time. The Fall-Line parts use a bespoke Viton O-Ring that resides within a clever internal channel. Viton O-Rings, due to their exceptional resistance to temperature extremes (-20°F to 400°F operating temp) and low gas permeability, have incredible aging characteristics and therefore eliminate the need for regular replacement.
