2.5L jetta automatic transmission troubleshooting codes?

[JuanGLS]

Hello I know I should post this somewhere else but not enough traffic on other threads...
I'm a noob so any help is greatly appreciated.

So my engine code is on and I got my car scanned. I got P0721 and p0720
ever since this light turned on all the P, R, D, N, S are highlighted at the same time.

Here is what it says

P0721
Definition: Output speed sensor circuit.
Explanation: Open or short circuit condition.
Probable cause: Poor electrical connection or failed output speed sensor.

P0720
Definition: Output speed sensor circuit range performance explanation.
Explanation: Open or short circuit condition.
Probable cause: Poor electrical connection or failed output speed sensor.

I don't know if it is the speed sensors on the wheels or the "transmission" one?
