MMX BMW F8X Billet Aluminium DCT Gearbox Oil Pan For F80 M3, F82/F83 M4 & F87 M2

The MMX BMW F8X Billet DCT Gearbox Oil Pan replaces the factory plastic sump with a precision-machined 6061-T6 aluminium unit built to overcome its limitations. It increases oil capacity, adds integrated cooling fins and internal baffling, and provides additional -8AN ports, delivering better cooling, better oil control and far greater durability for hard-driven DCT applications.

Why The Factory Pan Runs Short

The standard DCT sump is plastic, holds a modest volume of oil, and has no meaningful provision for cooling or for controlling oil movement. On a road car that is adequate. On a car used on track, DCT oil temperature climbs quickly, and high oil temperature is what triggers the gearbox to protect itself by limiting torque, at exactly the point in a session where the driver notices.

More Oil, More Cooling, Better Control

The MMX pan addresses all three factors at once. Increased capacity means more oil doing the work and a slower rate of temperature rise. Integrated cooling fins increase surface area to shed heat into the airflow underneath the car. Internal baffling keeps the oil where the pickup needs it under sustained cornering loads, rather than allowing it to surge away from the pickup on a long right-hander.

Additional -8AN Ports

The pan is machined with additional -8AN ports, allowing an external DCT oil cooler to be plumbed in for cars that need more thermal capacity again. That makes it suitable as a standalone upgrade or as the foundation of a full cooling solution on a serious track car.

Frequently Asked Questions

Is this only worthwhile for track cars?
The cooling and baffling benefits are most valuable on track, but the durability of a billet pan over a plastic one applies to any car.

Is an external cooler required?
No. The pan works as a standalone upgrade. The -8AN ports are there for owners who want to add a cooler later.

Does DCT fluid come with it?
No. Transmission fluid and a filter should be ordered separately, as the pan is fitted during a fluid service.

Why Choose The MMX DCT Pan?

DCT temperature is the single most common reason an F8X starts limiting torque on track, and the factory plastic sump gives nothing to work with. MMX addresses capacity, cooling and oil control in one part. R44 Performance supplies the MMX transmission range with UK stock and worldwide shipping.
