Bimmer ATC-300 Actuator Motor

Much like most modern transfer cases the ATC300 uses a shift actuator, or shift motor, to engage the 4 wheel drive system.

The ATC300 is used in the BMW 3 Series and 5 Series from about 2004 to 2013. There are several variations of the transfer case for those years, which are 27107599693, 27107599690, 27107613153, 27107613152, but luckily all of them use the same actuator - part number 27107546671.

Time, weather and use all contribute to the parts eventual failure, just like any other part, at which point will need to be replaced. To see all the parts we currently carry for the this unit please click here.
