good morning my name is ***** ***** I will assist

the 720 code is a code for output shaft speed. the computer sees your in drive and knows it should see a signal from the output speed sensor but nothing is being sent.

if you have reverse, then most likely you have a failed front clutch pack. the trans will have to come out and be inspected and most likely re built.
