Input/Turbine Speed Sensor Circuit Malfunction
High severity
What it means
The transmission input speed (turbine) sensor signal is missing or implausible. Without this signal, the TCM cannot detect torque converter slip or calculate gear ratio in real time, and shifts become harsh.
Is it safe to drive?
