This complete service kit includes all essential components required to properly service your transmission, helping to restore shift quality, improve efficiency and protect critical internal components.

Complete OEM Transmission Service Solution

This genuine BMW service kit provides everything required for a full gearbox service, eliminating the need to source individual components. Designed to meet BMW and ZF factory specifications, it ensures correct fitment, sealing and fluid performance.

Kit includes:

• 7 litres of OEM-spec transmission fluid

• Transmission oil filter

• Replacement oil pan (integrated filter design where applicable)

• All required gaskets and seals

• Sump plug

• All necessary installation hardware

Replacing the oil pan and filter together is essential on ZF 8-speed gearboxes, as the filter is integrated into the sump design on many variants.

Why Service Your ZF 8-Speed Gearbox?

Although often described as “lifetime fill”, transmission fluid degrades over time due to heat cycles and contamination. Regular servicing helps maintain the performance and longevity of your gearbox.

Benefits of servicing include:

• Smoother and more consistent gear shifts

• Reduced wear on internal transmission components

• Improved drivetrain efficiency

• Prevention of contamination and fluid breakdown

• Extended gearbox lifespan

This is especially important for higher mileage vehicles or those running increased power.

Genuine BMW & ZF Quality

This OEM service kit is manufactured to the same standards as the original components fitted to your vehicle. Using genuine BMW/ZF parts ensures:

• Correct fluid specification and viscosity

• Proper filtration performance

• Reliable sealing and leak prevention

• Compatibility with gearbox electronics and operation

Avoiding low-quality aftermarket alternatives helps protect against issues such as poor filtration, incorrect fitment or premature wear.
