Bmw automatic manual gearbox

The gearbox is lubricated with a dry-sump system for optimal lubrication and features no electronics beyond a sensor to tell the car what gear you are in for the shift assistant to help with rev-matching. The gearbox's input shaft is connected to a two-disc clutch from the F8X models with four friction layers, allowing longer clutch slippage for better launches. A dual-mass flywheel now features a larger starter gear rim and a stronger crankshaft flange with four metal plates, one more than before.

This should be good news for tuners that will inevitably seek to extract as much power as possible from the car with stock transmission components. That said, we have no doubt that the new G8X models will be plenty of fun to drive as standard too. It's quite a clever system. Add first comment. Now Buzzing. The back of the planetary gear assembly is connected to the flywheel, with a clutch set in between the two to allow the power coming from the flywheel to be disengaged from the gear set at will.

The other end of the planetary gear set is connected to a universal joint, which connects to a drive shaft. The drive shaft connects with the vehicle's drive axle to turn the wheels. When in automatic mode, the transmission functions normally. Power passes through the flywheel to the planetary gear sets. Active 5 years, 10 months ago. Viewed 17k times. Improve this question.

You don't know if it has been replaced before. And why would you do it if it causes no problems anyways? Other transmission choices are of course a fully manual transmission and a sport automatic—either standard or as an option on many models.
