BMW Drivetrain Parts for BMW 4 Series F33 (2014+)

Clear BMW chassis

Please ensure your correct model is selected

Building your perfect BMW is more than just adding horsepower and stiff suspension. Your drivetrain needs attention in order to deliver power effectively. Most BMWs feature comfortable clutch discs, heavy flywheels, long shifter throws, and open differentials. The drivetrain transmits power to the wheels, but can also be a source of power loss when it is designed for comfort rather than performance. Everything on this page will help you improve your power delivery and driving experience by providing custom Limited Slip Differentials, Short Shift Conversions, Performance Clutch Discs, Lightweight Flywheels, and anything else your BMW needs to be the perfect driving experience.

ECS Tuning's Polyurethane Transmission Mounts are designed to address the vital role of transmission mounts in your vehicle's suspension. The factory mounts are notorious for failures that can result in over-revving, mis-shifts, and in extreme cases, potential chassis damage. Our polyurethane mounts provide a robust solution, engineered for both street and track applications, guaranteeing enhanced performance while eliminating concerns about torn mounts.

Polyurethane stands out with its exceptional toughness, durability, and impressive wear resistance compared to rubber. It also exhibits resistance to water, oil, and grease while retaining its original shape even when subjected to significant compression. By reducing deflection, polyurethane facilitates effective power transfer. While there may be a slight increase in NVH (Noise, Vibration, Harshness), the benefits far outweigh this minor compromise in ride comfort. With a polyurethane durometer of 70A, our street mounts are versatile, offering both daily driving comfort and track durability. For more track-oriented enthusiasts, we provide stiffer mounts with an 80A durometer rating.

For a hassle-free installation, we supply a comprehensive DIY guide. ECS Tuning ensures that you are fully supported from start to finish.

This brass clutch pivot pin is an upgrade over the stock plastic pivot pin. The brass pin will last a lot longer than the plastic piece and may save you time and hassle later on. The original plastic pivot pin is known to fall out, snap, or just wear out over time. At the least you get a very annoying squeak every time you depress the clutch. In a worse case scenario, the clutch fork won't be able to push on the throw-out bearing and your clutch will be useless. The only time to replace the clutch pivot pin is when the transmission is removed, so this brass upgrade can be installed during clutch replacements or a rear main seal service.

Differential bushings are responsible for keeping your rear end planted during the delivery of power to the rear wheels. As these bushings age, they wear out and should be replaced. If you ever see your bushings are cracked, it is time to replace them. By eliminating the drivetrain deflection that factory rubber bushings permit, throttle response is improved, and the tendency for a car to “Wheel Hop” is significantly reduced. Upgrade to ECS Poly Diff Bushings and feel the difference!

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. For your 8-speed transmission, BMW recommends replacing your entire transmission pan and filter as the stock pan is constructed of plastic. This plastic pan will experience numerous drastic heat cycles over its lifetime, causing it to become weak and brittle, leading to potential catastrophic failure. Not only is this dangerous, but this is also very expensive when factoring in regular services. Upgrade your BMW's ZF transmission pan to PPE's Heavy-Duty Aluminum Transmission Pan and be done with pan replacements! PPE's one-of-a-kind transmission oil pan is cast from high-strength aluminum, allowing this pan to be used for the life of your transmission while also providing multiple benefits over your stock pan. Thanks to the thicker aluminum construction, internal heat fins, and integrated external cool fins, this pan helps promote reduced transmission fluid temperatures. PPE's trans pan has also been designed to allow for an additional quart of transmission fluid. The combined benefits of both cooler trans fluid and greater fluid capacity results in better lubrication, increased service life, and longer track sessions!

As per ZF's recommendations, Turner Motorsport suggests performing a full service on your 8HP automatic transmission every 50,000 miles. If your vehicle is modified and makes more power than stock or if your vehicle is regularly track-driven, we recommend shorter 30,000-mile service intervals. This will ensure your transmission's fluid is free from contamination which will help extend the life of internal transmission components like clutch packs and solenoids.

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.

Kit Includes:

  • Automatic transmission filter with associated hardware
  • Oil pan gasket
  • Drain plug with sealing washer
  • Fill plug with sealing washer
  • 7 quarts automatic transmission fluid

Fits the following BMW chassis with 8 speed transmissions:
E70, E71, F01, F02, F06, F07, F10, F12, F13, F13, F15, F16, F22, F23, F25, F26, F30, F31, F32, F33, F34, F36, G11
