Parking Brake Sucks?

I'd also recommend leaving it in reverse not first. Reverse has a lower gear ratio that gives it more holding power.

Continuing the interesting discussion...

I've read that if you're parked on a hill facing downward, you should put the car in reverse. If you facing up a hill, you should park in 1st. This way the car won't be able to roll if the hill is steep enough since the gear you selected is opposite the rolling direction. Now I don't know how realistic a car rolling forward in 1st gear is. It's a tall enough gear that it would take one hell of a steep slope to make it roll. But if you park on a hill in 5th, I'd bet the car may roll forward (ebrake not engaged).

that doesn't make any sense. if the car is in an opposing gear and rolls, it will simply turn the engine backwards. its no harder to turn the engine backwards than forwards. and yes, higher gears like 3rd or higher will not hold the car because it is easier for the transmission to rotate the engine due to the torque multiplication.

Actually you'd be wrong. 1st gear is 3.794, reverse is 3.446. 1st wins.

Damn I stand corrected, wonder why reverse is so high.

Not sure, it was that way in the 350 as well, in case you want to do 45mph in reverse I guess.
