P0720-OUTPUT SPEED SENSOR ERROR
WHEN MONITORED
The transmission gear ratio is monitored continuously while the transmission is in gear.
SET CONDITION
If there is an excessive change in output RPM in any gear. This DTC can take up to five minutes of problem identification before illuminating the M.I.L.

p0733 Gear 3 Incorrect ratio
This code is related to your transmission. You have gear ratio error codes in 1st, 2nd, and 3rd gear. You could check your transmission fluid and see if it's cherry red or burnt looking. My guess is you have a transmission that's gone out. Sorry for the bad news.but it's my line of work. If you had a input speed sensor code then I would say it's a problem with the sensor but since you didn't mention it's probably a transmission problem.
