The range box also selected reverse giving 6 reverse gears with speeds similar to medium in forwards. All gear changes were made with the use of a dry clutch. This gearbox then had a 2-speed powershift section added after the dry clutch and before the 6-speed gearbox. This resulted in 36 forward gears (2×6×3) and 12 reverse (2×6×1).

The piston rod connects by levers to the reversing gear, which operates in the usual way, according to the type of valve gear in use. The Ragonnet power reverser The Ragonnet power reverse, patented in 1909, was a true feedback controlled servomechanism .
For reverse gear, an idler gear is used to reverse the direction in which the output shaft rotates. In many transmissions, the input and output shafts can be directly locked together (bypassing the countershaft) to create a 1:1 gear ratio which is referred to as direct-drive .
Typically the multi-plate clutches are arranged on the main shaft or on the counter shaft. The forward reverse section of the gear box is generally located in the forward section as close to the engine as possible. This is beneficial to the forward reverse control elements as they are not subjected to the high relative torque.
