There should be a line connecting the solenoid of the transmission to the ECU. It could be the wiring is bad or the contacts need cleaning or the IAC valve may need cleaning or is not working.

Your wiring is fine if the engine runs most likely. Auto Zone performs free testing on the ECU to tell you what is wrong. The idle speed control is most likely faulty if the TPS was set correctly

some cars may have interlock with the brake switch to the shift lever inter-lock. have someone step on the brake, if brake light won't come on, suspect the brake switch is preventing the shift.

go to an auto parts store that will give Free trouble code scan

2002 mazda proteget vibrates when in reverse idles fine fine in drive

Check you motor mounts. With someone in the car and e-brake and main brake applied; Put vehicle in drive and bring RPMS UP and then let off. If you see the motor move excessively then the mount is broken on the side that lifts up. Put it in reverse and do the same. both mounts can be broken and there is usually a third mount so check them all.

1995 mazda protege, need front engine mount, do i need to get two or get 1 front and then 1 for right side near passenger side? new to auto repairs lol.

i would replace all the mounts at the same time. it's good practice and you probably never have to do it again.
