Deere 850c code

Hi guys! First time posting on this forum. I have a Deere 850c dozer. Today it kicked out of gear throwing a F645 code. Any help would be greatly appreciated.

    Welcome to HEF 9550 ! First we need a serial number. What particular symptoms are you having? F645 code is Transmission Shutdown, Hydrostatic Pump Speed Sensor Circuit.

    X900376 yesterday it kicked out of the forward drive position flashing return to neutral. If we cycled the lever from reverse to forward it would move for a short time. My guess it’s a bad connection or sensor. Just would like to know where the sensor is on the machine. Thanks
