Getrag 7DCL750 Clutch Pressure Sensor 40 Bar
The Getrag 7DCL750 Clutch Pressure Sensor 40 Bar from Hollywood Mechanic is a critical component in the dual clutch transmission pressure management system. The gearbox control module uses this sensor to monitor hydraulic pressure in the odd or even clutch pack in real time. When the sensor fails, the module loses pressure feedback for that clutch. The transmission then skips all gears on the affected shaft. This causes the gearbox to skip all even gears and reverse, or all odd gears, depending on which sensor has failed.
Two Sensors Required Per Gearbox
This sensor monitors one clutch pack. Since the Getrag 7DCL750 uses separate odd and even clutch packs, each clutch requires its own dedicated 40 bar pressure sensor. Because of this design, two sensors are required per gearbox. When ordering, confirm whether you need the odd clutch sensor, the even clutch sensor, or both. Hollywood Mechanic recommends replacing both sensors at the same time when either one has failed.
Valve Body Gasket Leaks Can Cause Pressure Faults
Before replacing the sensor, a qualified technician must perform a thorough diagnostic procedure. Since valve body gasket leaks can cause clutch pressure faults that mimic a failed sensor, the root cause must be confirmed before parts are ordered. If the valve body gasket is leaking, replacing the sensor alone will not resolve the fault. Hollywood Mechanic recommends a complete rebuild of the Clutch Control Pack when pressure faults are present. The CCP Rebuild Kit and individual Gaskets are available separately.
Fault Codes Associated with Clutch Pressure Sensor Failure
When the Getrag 7DCL750 Clutch Pressure Sensor 40 Bar fails or receives a distorted signal, the gearbox control module generates specific fault codes. Potential faults associated with this sensor include but are not limited to:
- P0841 – Odd clutch pressure signal invalid
- P0842 – Odd clutch pressure sensor too low
- P0843 – Odd clutch pressure sensor too high
- P0846 – Even clutch pressure signal invalid
- P0847 – Even clutch pressure too low
- P0848 – Even clutch pressure sensor too high
- P0933 – Hydraulic pressure sensor signal invalid
- P0934 – Hydraulic pressure sensor too low
- P0935 – Hydraulic pressure sensor too high
- P1902 – APP_CLUTCH_PRESSURE_ODD, too high (odd shaft pressure command signal too high)
- P1903 – APP_CLUTCH_PRESSURE_ODD, too low (odd shaft pressure command signal too low)
- P1904 – APP_CLUTCH_PRESSURE_ODD, invalid signal (odd shaft pressure command signal not valid)
- P1905 – APP_CLUTCH_PRESSURE_EVEN, too high (even shaft pressure command)
- P1906 – APP_CLUTCH_PRESSURE_EVEN, too low (even shaft pressure command signal too low)
- P1907 – APP_CLUTCH_PRESSURE_EVEN, invalid signal (even shaft pressure command signal not valid)
