Auto trans pressure switches - which side is which?

[wwheeler]

I searched and could never find an answer to which side is the drive and which is the reverse. I know it can be tested to determine, but hoping to save some time and also document it on this site.

Thanks,

I replaced the faulty transmission pressure switch today. And which side is which.........?

Left side switch is reverse and right side switch is drive.
