I scanned my car and the code p0720 came up. It says the transmission speed sensor. I would like to know where is the transmission speed sensor is located? Would you happen to have a diagram of it?

Good afternoon.

This code indicates the output speed sensor reading is missing. I would verify there is power and that the connector is not damaged.
