Seriously though, 1st when pointing uphill, Reverse when pointing downhill, and I'll typically put it in 1st when level just out of habit. I don't think there's much difference between 1st and 2nd except that 1st gives more resistance, with the tradeoff that it could theoretically put more strain on the gearbox.

Leaving it in Neutral definitely will NOT cause any problems with the gearbox (just the opposite in fact, Neutral is the easiest on the gearbox of all options), but if you want maximum hold resistance AND very little strain on the gearbox, when parking on a hill, follow this procedure:

1. Get your car parked and your wheels turned whichever way is appropriate for the direction of your incline.

2. Clutch in, foot on the brake, shift to Neutral.

3. Pull parking brake all the way, release foot brake. The car will roll slightly and rest on the emergency brake.

4. Shift into 1st or Reverse as appropriate, turn engine off, clutch out.

That way you put all of the resistance load on the brakes rather than the gearbox, but the gearbox is still engaged to provide a backup source of resistance if the brakes fail somehow.
awesome guide. will definitely follow
