We specialise in the diagnosis, maintenance, repair, and electronic driver profile adaptation of all types of automatic gearboxes.


Continuous Variable
Transmission (CVT)

This type of automatic gear change is called CVT (Continuous Variable Transmission), since the developments are not determined by a pair of gears, but rather by two pulleys made up of conical elements linked by a chain that transmits the power, and this makes it possible to have an infinity of gears with the engine running at its optimum value in order to deliver the torque more efficiently.

Piloted Twin
Clutch transmission

The double-clutch gearbox is a sequential, semi-automatic type of gearbox. The operation is based on the use of an automated system consisting of a double clutch and double set of gear selectors; one for the even gears and one for the odd gears.

Traditional hydraulic
Automatic Transmission

The predominant type of automatic transmission is that which operates hydraulically, using a torque converter and a set of planetary gears to multiply the torque. The torque converter consists of a pump (which pumps out the hydraulic fluid and a turbine (which receives the fluid). The pump emits the fluid with a certain force and the turbine pump receives a large part of its mechanical force, around 90%, with this percentage even reaching 100% when the converter has a “converter clutch” or hydro-mechanical tap. The planetary gears then receive the torque via the friction disks and modify the output revolutions needed for each gear. For years, these signals have been detected electrically and processed electronically, commissioning a calculator or transmission control module (TCM) to activate the control valves, which are now electro-hydraulic. All the makes have this type of transmission. It is the most evolved type, since it has been on the market for many years, with the first gearboxes being fitted as long ago as the 1950s.



This type of transmission is a mixture between a manual and an automatic gearbox. It is a manual gearbox with an electro-hydraulic robot that performs the movements of the lever and clutch (conventional dry disk) that the driver would perform if the vehicle were manual. It is a poorly-evolved type of gear change and a little slow between the gears.
