Transmission Speed Sensor 5- / 6-speed SMG
This sensor provides the speed signal of the transmission input shaft. The speed signal is required by the SMG control unit to control the transmission system, adjusting properly the shaft speeds before engaging and disengaging the different gears.

It is suitable for all extreme conditions and guarantees full performance from -40 Degree Celsius to over 130 Degree Celsius system temperature.
Pentosin CHF 11S meets DIN 51 524T3 and ISO 7308 specification standards.
Pump Motor 5-speed SMG
The pump motor drives the gear pump, which generates the pressure for the SMG transmission. Both parts together form the hydraulic pump. Without hydraulic pressure, the transmission cannot perform any action – neither change gears, nor operate the clutch. Therefore, the hydraulic pump is the most important component in the system.
In most cases, it is sufficient to replace only the electric motor, as this is a wearing part. The gear pump fails only very rarely. Another advantage is that when only the pump motor is changed, the hydraulic system does not need to be bled afterwards, unless it has been opened.
