Use from the manumatic features are usually accomplished either via paddles located beside the steering column, or "+" and "-" controls within the gear selector. Some vehicles give motorists equally ways to request a guide gear assortment.

The locking sequences on the epicyclic equipment train are attained by hydraulic strain working brake bands or multi-plate clutches.
1 (also labelled "L"): Restricts the transmission to 1st equipment only, often known as a "reduced equipment". This is useful when a big torque is necessary within the gearbox auto wheels (as an example, when accelerating up a steep incline); even so use at greater speeds can operate the motor at an too much speed, risking overheating or hurt.
