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.

These include gearbox seals, o-rings, gaskets, automatic transmission filters, backup light switches, mounting bolts, flanges, collar nuts, screw plugs, Mechatronics, and more.

If allowed in the rules these solid aluminum transmission mounts offer many advantages over a urethane or Delrin mounts. It's no wonder that these mounts have found their way into the top BMW racers in the country. These are machined from solid aluminum and have zero deflection, engine torque will cause a rubber or urethane mount to flex or deflect allowing more torque to passed through the drive line (instead of being wasted winding up the mount). This puts the shift linkages in better consistent alignment. And unlike rubber or urethane the aluminum has zero wear and is not affected by leaking oil or other fluids so this is likely the last set of transmission mounts you will ever need. We very strongly recommend using the solid transmission and engine mounts together as a complete kit, mixing a rubber mount with a metal mount will cause undue stress on the mounting points and will lead to a failure. We never advise using a solid mount unless a corresponding solid mount is also used.

These are a no-compromise design for all-out racing use, full solid aluminum mounts should not be used on street-driven cars since there is no material to absorb vibration making these quite harsh for regular street use (track cars don't care about noise).

Product features and benefits:

  • Crisper throttle response, positive shifter location, direct power transfer
  • Precision machined billet 6061-T6 aluminum housing
  • Grade 10.9 stud - fear not, big turbo owners
  • Engineered in-house and made in America

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. Automatic transmission Level II kit contains what you need to do an automatic transmission fluid and filter service. For limited time includes a FREE bottle of Redline WaterWetter®! WaterWetter® is a unique wetting agent that reduces coolant temperatures by as much as 30°F. Pour it into your cooling system to provide rust and corrosion protection in plain water for racing engines, and to improve coolant heat transfer properties. Add it to new or used antifreeze to improve the heat transfer of both ethylene and propylene glycol antifreeze/coolants. Compatible with aluminum, cast iron, copper, brass and bronze components. Kit Includes: Automatic transmission filter with hardware Oil pan gasket Drain plug with sealing washer Fill plug with sealing washer 8 quarts Redline D4 automatic transmission fluid FREE bottle of Redline WaterWetter®
