OBD-II Code Transmission Control Module (TCM) failure is defined as a Hydraulic Pressure Sensor Circuit High
The clutch uses hydraulic pressure to engage and disengage the clutch as well as shift gears. Pressure is stored in the Accumulator. The Accumulator Pressure Sensor tells the Transmission Control Module (TCM) how much pressure is in the system. If the sensor sends back an implausible signal, code P0935 is stored.
