P0956 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.
Some vehicles equipped with automatic transmission will give the driver the option of selecting the desired gear while driving, known as Autostick Shifting. The shifter will usually either have a + ahd - button on it, or shift side to side when in Drive. If the downshift switch does not function correctly, code P0956 will set and the Autostick shift function will be disabled.
