Transmission

Formula 1 cars are usually fitted with seven-speed semi-automatic gearboxes. Regulations direct that the cars have minimum four forward gears, and maximum seven. The cars must also be equipped with a reverse gear. The cars must have no more than two driven wheels. Constantly Variable Transmission (CVT) systems are also not permitted in F1 cars. Regulations discourage the use of traction control systems or devices for these could assist the drivers in the race.

Clutch Operating Devices
If the car has been fitted with multiple clutch operating devices, all these must have the same mechanical travel characteristics and be mapped identically. Designs which assist the driver to hold a position are not allowed. The minimum and maximum travel positions of the clutch operating device have been specified. The operating device must correspond to the clutch fully engaged in normal rest position and fully disengaged positions. Only typical inherent hydraulic and mechanical properties are allowed in Formula One cars. Any system which assists in the spinning of driven wheel is not permitted. The rules also prohibit any device or system which notifies the driver of the onset of wheel spin.

What is Prohibited
No car may be equipped with a system or device which is capable of preventing the driven wheels from spinning under power or of compensating for excessive throttle demand by the driver.
