Genuine BMW F8X & F1X 7 Speed DCT Transmission OEM Service Kit (F Series M Cars)

Give your BMW M car's dual-clutch transmission the complete service it deserves with the Genuine BMW F8X & F1X 7-Speed DCT Transmission OEM Service Kit. Designed for BMW M models equipped with the 7-speed M DCT gearbox, this complete maintenance package includes the key Genuine BMW components and transmission fluid required for a thorough DCT service.

The kit is suitable for popular F-Series BMW M cars including the F80 M3, F82/F83 M4, F87 M2, F87 M2 Competition, F10 M5 and F06/F12/F13 M6. Rather than sourcing the sump, filter, sealing components and fluid individually, this package brings the essential service items together in one convenient kit.

BMW's M DCT is a sophisticated high-performance transmission that relies on the correct fluid, filtration and sealing components to operate consistently. Replacing the old transmission oil and service components helps maintain clean fluid circulation and provides an ideal opportunity to inspect the system for leaks or contamination.

For owners maintaining a standard road car, modified BMW M car or regularly driven performance build, this Genuine BMW DCT service kit provides the correct OEM components for servicing the factory transmission.

What Is the BMW 7-Speed M DCT?

BMW's 7-speed M Double-Clutch Transmission, commonly known as the M DCT, was used across some of the most popular BMW M cars of the F-Series era.

Unlike a conventional torque-converter automatic, a dual-clutch transmission uses two clutches to manage alternating gear sets. This allows the gearbox to pre-select the next ratio and deliver extremely fast gear changes while retaining the direct, responsive character expected from a performance transmission.

The 7-speed DCT became a defining feature of models such as the F80 M3, F82 M4 and F10 M5, combining rapid shift speeds with full automatic operation when required.

Because the transmission uses specialised fluid for lubrication, cooling and hydraulic operation, using the correct BMW components and oil is essential when carrying out servicing work.

Why Service Your BMW M DCT Transmission?

The DCT contains clutches, hydraulic control systems, gears, bearings and filtration components operating under significant heat and load.

Over time, transmission fluid can accumulate wear particles and gradually lose some of its original characteristics. The filter also performs the important job of trapping contamination before it can circulate through sensitive transmission components.

A comprehensive DCT service replaces the used fluid and filtration components, helping provide:

• Fresh, clean transmission fluid
• Effective filtration
• Correct lubrication of internal components
• Consistent hydraulic operation
• An opportunity to inspect for leaks or abnormal contamination
• Preventative maintenance for a valuable high-performance transmission

This is particularly relevant for modified vehicles, cars that regularly experience hard driving or examples where the transmission's previous service history is unknown.

Genuine BMW Sump, Filter & Gasket

A proper transmission service involves more than simply draining and replacing the fluid.

This kit includes the Genuine BMW transmission sump, filter and sealing components, allowing the service to address the parts responsible for containing and filtering the oil as well.

Replacing these items during servicing helps ensure the transmission receives clean fluid through a fresh filtration system while restoring the sump sealing surfaces with new OEM components.

Using Genuine BMW parts also ensures the replacement components are designed around the original gearbox rather than relying on universal aftermarket alternatives.

Genuine BMW DCT Transmission Oil Included

The kit also includes the correct Genuine BMW transmission oil required for the applicable 7-speed M DCT.

BMW's DCT transmission fluid is specially formulated for the demands of the dual-clutch gearbox, where the oil must perform multiple tasks including lubrication, cooling and supporting hydraulic control.

Using the correct fluid specification is especially important with a sophisticated transmission such as the M DCT. A generic automatic transmission fluid should not be substituted unless it carries the exact approval required for the gearbox.

By supplying the fluid as part of the complete kit, you have the correct oil ready for the service without needing to calculate and source it separately.

Compatible BMW M Models

Designed for selected F-Series BMW M cars equipped with the factory 7-speed M DCT, including:

• BMW F80 M3
• BMW F82 M4 Coupé
• BMW F83 M4 Convertible
• BMW F87 M2
• BMW F87 M2 Competition
• BMW F10 M5
• BMW F06 M6 Gran Coupé
• BMW F12 M6 Convertible
• BMW F13 M6 Coupé

Compatibility is gearbox-specific, so the kit is intended for vehicles equipped with the corresponding 7-speed BMW M dual-clutch transmission.

Manual-transmission versions are not compatible.

Particularly Relevant F8X Applications

For many R44 Performance customers, the most relevant applications are the F8X-generation M cars.

This kit is suitable for DCT-equipped examples of the:

• F80 M3
• F82 M4
• F83 M4 Convertible
• F87 M2
• F87 M2 Competition

These models are frequently modified for increased power, road performance and track use, all of which can place additional thermal and mechanical load on the drivetrain.

Keeping the transmission fluid and filtration system properly maintained is therefore an important part of looking after the complete car, not just the engine.

F10 M5 & F06/F12/F13 M6 Compatibility

The same principle applies to the larger S63-powered F10 M5 and F-Series M6 range.

These cars combine substantial torque with the rapid-shifting 7-speed M DCT, making transmission condition an important consideration as the vehicles age.

The service kit is suitable for:

• BMW F10 M5
• BMW F06 M6 Gran Coupé
• BMW F12 M6 Convertible
• BMW F13 M6 Coupé

For higher-mileage examples or cars with incomplete service records, a comprehensive DCT service can be a valuable piece of preventative maintenance.

When Should You Service the DCT?

Transmission service requirements can vary according to model, mileage, vehicle use and previous maintenance history.

Cars subjected to frequent hard driving, increased engine output or circuit use can place greater demands on the transmission fluid than vehicles used primarily for normal road driving.

We recommend reviewing your vehicle's service history and following the appropriate BMW workshop guidance for your exact model.

If the transmission has unknown maintenance history, visible leaks, contaminated fluid or other symptoms, professional inspection is recommended before simply replacing service components.

Professional Installation Recommended

Servicing the BMW M DCT requires the vehicle to be level and involves specific procedures for filling the transmission and checking the final fluid level at the correct temperature.

For this reason, we strongly recommend installation by a BMW specialist or technician experienced with M DCT transmissions.

Correct procedure is essential to ensure:

• The sump and sealing components are installed correctly
• The transmission is filled with the correct quantity of fluid
• Final fluid level is checked at the specified temperature
• No leaks are present after servicing
• The transmission operates correctly following the work
