A transmission solenoid or cylinoid is an electro-hydraulic valve that controls fluid flow into and throughout an automatic transmission. Solenoids can be normally open or normally closed. They operate via a voltage or current supplied by the transmission computer or controller.
Saab's Sensonic system was electro-hydraulic, using an electric motor or solenoid connected to a hydraulic clutch actuator, whereas Ferrari's Valeo system was electro-mechanical, using an electric motor or solenoid, connected to the mechanical clutch system.

Some high-performance sport bikes use a trigger-shift system, with a handlebar-mounted trigger, paddle, switch, or button, and an automatically operated clutch. [13] [106] [107] Some dirt bikes use this system, which is sometimes referred to as an auto-clutch transmission. [31] [29] [32] These include the Honda CRF110F [108] [109] and Yamaha TT ...

Automated manual transmissions can be semi-automatic or fully-automatic in operation. Several different systems to automate the clutch and/or shifting have been used over the years, but they will generally use one of the following methods of actuation for the clutch and/or shifting: hydraulic or electro-hydraulic actuation, [12] electro-mechanical, [13] pneumatic, [6] [14] [15] electromagnetic ...
The original Hondamatic, like all following Honda automatics, featured gears on parallel axes rather than planetary gears like most other automatic transmissions. The two gears for each ratio - one driving and the other driven - are in constant mesh and each ratio is engaged by a dedicated clutch connected to one of the ratio's two gears.
This allows for more precise control of shift points, shift quality, lower shift times and manual control. The first five-speed automatic was the ZF 5HP18 transmission, debuting in 1991 on various BMW models. The first six-speed automatic was the ZF 6HP26 transmission, which debuted in the 2002 BMW 7 Series (E65).
