FAQ
Sensors & Electronics - Common Questions
What does a transmission speed sensor do?
A transmission speed sensor measures the rotation of the input and output shafts. The transmission control module uses these readings to time shifts, calculate gear ratio, and compare expected versus actual speeds to detect slip.
What is OBD-II code P0700?
P0700 is a generic code indicating the transmission control module has detected a fault. It does not name the specific problem, so a vehicle-specific scan tool is needed to read the accompanying TCM sub-codes for diagnosis.
What are the symptoms of a bad shift solenoid?
Symptoms of a failing shift solenoid include harsh or delayed shifts, getting stuck in one gear, slipping, and a check engine light. Codes in the P0750 to P0770 range typically point to specific solenoid circuits.
