Question about Gentex 2001 Chevy Venture - All Venture models - K5 Auto-Dimming Rear View Mirror w/Compass
When the code P0720 is set in the Powertrain Computer, it means that the Powertrain Computer or PCM is not seeing a rational speed signal from the Output Sensor or, there is a greater than specified RPM difference between the rotational speed of the Input RPM Sensor and the Transmission Output Speed RPM Sensor. This can occur during shifting or when driving at steady speeds in the same gear. It often implies that the transmission is slipping.
You could try replacing the Vehicle Speed Sensor to see if the problem goes away, or you will need to get the transmission serviced.
