The DCT transmission is a marvel of engineering and remains to this day the best automated transmission BMW M ever fitted to a car.
Unfortunately for us, BMW didn't expect its DCT transmissions to leak as we now know today.
Upgrading its main pan is a core component to bulletproofing this transmission.
In this Special Series, I document my DCT transmission leaks, its major service plan, updated GTS filling specifications and the OE+ GTS DCT main oil pan.

Increased Oil Capacity.
Improved Oil Flow.
Fits with OE hardware
The pan includes the GTS style "banjo" bolt and Loctite 574 flange sealant.
The banjo bolt allows DCT fluid filling to GTS spec and beyond, without requiring tilting the car to the driver side.
I highly recommend professional installation. The DCT transmission is an expensive piece of mechanical and electronic equipment. An overlooked step could cost you a lot of money.
