It works like a 4th gear the same as late vehicles with an automatic overdrive transmission. There is no manual gear selection as in a T5. The overdrive selection is made by engagement of an electric solenoid in conjunction with a speed governor. It can be temporarily disengaged for passing by engaging a kickdown switch in the same manner as driving a vehicle with an automatic transmission.
The electrical components include a solenoid, governor, kickdown switch, relay, and wire loom. The solenoid and governor are components of the BW overdrive unit mounted on the rear housing.

This type of overdrive also uses a cable which is primarily used to disengage or engage the OD. For most driving the cable is pushed in to engage the system.
