If the vehicle will not move in drive only then we need to start with checking the fluid. If it is low or in poor condition, then you need to change the fluid.

If the fluid is proper level, then the next thing is to check and find out if the shifter is connected and moving the manual valve.
Please see the attached info below on the shifter. If the shifter is okay, then we need to get into the pump or even solenoid issues.
However, they are less likely so let's run through this info and see what we have.
Thanks
