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.

This Automatic Transmission Service Kit for your ZF 8HP transmission is a great choice to ensure your transmission is properly cared for, ensuring many more years of smooth and reliable operation. Transmission fluid can break down over time and filters can clog, leading to poor fluid flow, which can cause starvation of sensitive components and accelerated wear and tear. Replacing the fluid and filter regularly will make sure that internal transmission components are properly lubricated and cooled, helping to extend the lifespan of your transmission.

This is the OEM transmission rear output seal for cars with the S6S420G or GS7S47BG transmissions. It is a good idea to replace all the seals on the transmission whenever replacing a clutch as it is much easier to do while the transmission is down off the car and these seals commonly develop leaks over time. This seal works with either the manual transmission or the SMG transmission.

This item fits the following BMWs:
2001-2006 E46 BMW M3
1993-1995 E34 BMW 540i
1997-2003 E39 BMW 540i M5

GA8HP 8 speed automatic transmission. Automatic transmissions are reliable, shift smoothly, and can last without issue so long as they are properly maintained. Over time, the transmission fluid becomes thick and the filter becomes contaminated with small metal particles. This can cause excess wear, high transmission operating temperatures, and eventual failure. To prevent this we recommend changing your filter, fluid, and seals to ensure your transmission continues to operate flawlessly. We recommend filter and fluid changes every 50,000 miles.
