P2746 Severity
Identifying an OBD code is just the start of a complete diagnostic routine. Most trouble codes are caused by a sensor reporting a value that is out of range. Just replacing a sensor may not fix underlying issues. Be sure to understand the code, the part or system in your car that the code refers to, and the risks of delaying professional repair.
Proper diagnosis will save you time and money on unnecessary repairs.
Urgent codes indicate immediate action is necessary. These are urgent and significant malfunctions that can cause severe damage to the vehicle or harm the driver and passengers.
The Intermediate Shaft Speed Sensor tells the Transmission Control Module (TCM) how fast the intermediate shaft of the transmission is spinning so the correct gear can be engaged. When the TCM receives an inaccurate signal from this sensor, it can't properly shift the vehicle from gear to gear as the vehicle needs to change speed an rates of acceleration. The engine control module (PCM) or TCM will set this code.
