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.

The ZF 8-speed transmission found in the 2021+ BMW G8X M3/M4 is a stout and snappy unit that's capable of withstanding the onslaught of torque brought on by the S58 engine it's mated to. Add a tune and some bolt-ons, and the stock cooler just can't keep the ZF 8HP safe. This inadequacy can lead to high transmission oil temperatures, sluggish shifting, and potential transmission damage. Fortunately, the engineers at Mishimoto have developed a transmission cooler to maintain optimal fluid temps and keep your ZF 8HP running in peak condition. The Mishimoto 2021+ BMW G8X M3/M4 Performance Transmission Cooler excels with its impressive 41-percent increase in core volume, delivering superior cooling efficiency compared to the stock cooler and keeping your transmission cool even in the most demanding driving conditions. This transmission cooler also offers a generous 17-percent increase in fluid capacity to increase the cooling potential of the entire system. Internal cooling fins increase the surface area in contact with the fluid to improve heat transfer and efficiency. The dual-pass design keeps fluid in the cooler longer, removing more heat without affecting airflow to other cooling components behind the transmission cooler. High fluid temps aren't the only worry on the track or the road; your trans cooler sits front and center in the grille, taking every hit from road debris. That's why we've included a durable steel stone guard to protect the trans cooler and keep fluid where it belongs. Installation is quick and easy, as no modifications are required. Like all Mishimoto products, the Mishimoto 2021+ BMW G8X M3/M4 Automatic Transmission Cooler comes with the Mishimoto Lifetime Warranty, providing peace of mind and confidence in your investment. Features: Direct fit for ZF 8HP equipped 2021+ BMW G8X M3/M4 17 percent increase in fluid capacity for added cooling potential 41 percent increase in core volume for fast and efficient cooling Dual-pass design improves cooling performance without reducing airflow to other components Includes removable steel stone guard for protection against road and track debris Internal fins increase cooling surface area and heat transfer 17 rows core vs. 14-row stock cooler for increased cooling surface area Mishimoto Lifetime Warranty Includes: (1) Transmission Cooler with Hard Lines Mishimoto Lifetime Warranty
