Do you need to fully stop before engaging reverse? Like let's say you're backing up, but disengage and you're in N, but then need to go back in R...will you need to fully stop?

If you're already rolling backwards you can double-clutch into reverse, but it might be tough to get good enough at it to avoid grinding unless you park facing uphill and back out of your parking space every day.

If you take the pointing off the ends of teh teeth, then you are more likely to get tooth-butt and block out of Reverse unless you feather the clutch to rotate the input shaft slightly.

He thought for sure that it would at least cause a nasty grinding sound, even if it didn't destroy the transmission. I was in the car when he tried it. Nothing happened. Nothing at all.
I once threw my 1971 Ford into park going about 15-20 mph. It made a nasty sound like a very loud ratchet and finally when almost stopped the parking pawl fell into the slot and the car came to an abrupt stop. Didn't break off the pawl. The Toyota Camry must have a different mechanism for engaging park.

I don't think it's a different mechanism...I believe it still has a basic parking pawl. What probably changed is the intelligence of the vehicle. It basically "knows" that Park shouldn't be engaged while the car is moving, so it simply doesn't allow it. Chalk it up to electronic controls and ECU/PCMs, I guess.
