description
At the luxury brand Maybach of the 1930s, buyers had a wide range of options to have their vehicle “bodyworked” according to their individual requirements and personal style.
The vehicles had a semi-automatic 3-speed gearbox with gear preselection using small levers on the steering column and an additional overdrive gear, which was also engaged with a lever on the steering column.
The switching process can be found in the operating instructions; When starting off, after depressing the clutch, the selector lever on the steering column had to be set to low gear, the gear lever had to be set to gear selection (forward or reverse gear) and then engaged. The further gears were shifted automatically after the gas was released by preselecting the desired gear on the steering column. In this way it was possible to switch up and down. The driver did not need to operate the clutch, he just had to watch out for the synchronization of the gearbox, ie the engine had to be turned down when shifting up and brought up to speed when shifting down . To stop the vehicle, the operating instructions recommended: take off the accelerator, apply the foot brake, disengage the clutch, put the gear lever in neutral, apply the handbrake and set both levers on the steering column to starting gear.
The overdrive had been simplified since the Maybach 12 so that the driver can only switch the overdrive on or off by moving the lever. The actual switching process is then controlled by negative pressure.
