BMW Drivetrain Parts for BMW G42 M240i xDrive B58 3.0L

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.

Servicing your rear differential at regular intervals is important to ensure you maintain both performance and a long lifespan. Over time, the differential fluid can break down, lose its lubricating properties, and become contaminated with metal shavings and debris. Regularly replacing the fluid ensures that the gears and limited slip differential clutch packs are adequately lubricated, reducing wear and tear. Regular maintenance also helps identify potential issues before they become major problems.

This kit includes Genuine BMW differential fluid designed specifically for your M Sport differential and a brand new fill plug. The factory plugs include a rubberized seal that compresses over time and may not seal properly when reused.

One unique aspect of performing this service is the removal of the lower differential temperature sensor. Unlike many typical BMW differentials, this differential does not use a traditional drain plug and instead uses the temperature sensor as a drain plug. This sensor is removed to drain the differential fluid and is replaced before refilling. If you'd like to replace this sensor as well (not included in this kit), please see our recommended items or search BMW part number 33107847469.

NOTE: This kit includes 3 500ml bottles of diff fluid. BMW claims that only 1 Liter of fluid is necessary, but we found that 2 500ml bottles were insufficient. The third bottle included also allows for a minor flush of the old differential fluid before refilling.

Wheel bearings can need replaced for a number of reasons, the most common being normal wear. If there is a loud humming, growling, or metal-to-metal noise while driving, it's likely that the bearing has failed. A simple way to check your bearing is to lift the wheel off the ground and try to move the tire back and forth by pushing the top and bottom of the tire in. If there is play, this commonly means the wheel bearing is worn out or has failed completely. The wheel hubs and bearings are already pressed together, simply bolt this new hub assembly to your rear wheel carrier.

If you have to drop or pull your transmission for any reason, the input and output shaft seals are one of the best "while it's out" maintenance items you can replace. Worn out shaft seals can allow transmission fluid to leak out, possibly shortening its life if the fluid level gets too low. This repair kit includes the basic components needed to replace both the front and rear seals.

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. This item fits the following BMWs: E71,E89 Z4,F06,F10,F12,F13,F15,F16,F22,F25 X3,F26 X4,F30,F31,F32,F33,F34,F36

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. Kit Includes: Automatic transmission filter Oil Pan Gasket & Installation Hardware Drain plug with sealing washer Fill plug with sealing washer 7 Liters of Genuine BMW ATF 3+ Fluid NOTE: Depending on the model, an additional liter of fluid may be necessary if you are draining your oil cooler or removing the valve body. 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.

BMW's latest iteration of Limited Slip Differentials features a design utilizing clutch packs that are engaged and disengaged by an electric motor. As the electric motor activates, a set of gears adjusts a pressure plate which compresses these clutch packs. As these clutch plates are compressed, the amount of "lock-up" increases, allowing for a range of wide range of engagement, from completely open to almost fully locked. This ensures your BMW is able to transfer power to the ground regardless of the conditions for optimal performance and handling.

If you've noticed excess tire slippage in wet or snowy conditions, there is a chance this electric actuator motor has begun to fail and will need to be replaced to restore your M Sport differential's functionality. This kit includes all of the basic components necessary to replace this motor. 

Referred to by BMW as an Actuator, Position Sensor, and Set Positioning Motor
