Seems Legit Garage - DCT Overfill/Dry-Break Kit

BMW Motorsport overfilled their GT4 DCT transmissions for a reason, it was to reduce the chance of oil cavitation reaching the oil pump and reducing precious pounds of pressure. This is most important during high G corners and high revs. To combat this, use this kit, like BMW Motorsport did, to overfill your oil by a quart. Super handy for clean fills as well! 

The dry break connects without any tools and without leaving any fluid. To fill transmission, follow factory fill procedure. Once complete, install this kit and add a quart of oil using any fluid pump via the included hose nipple.
