Ever since I heard Cartalk recommend (and recommend seriously, not as a joke) flushing the radiator on an old 911 (yes, the air-cooled models) I really don't have much respect for them. Even when they agree with me.Originally posted by: Pacfanweb
CartalkLeaving the car in gear helps keep it from rolling. But it's no guarantee. If the clutch is slipping, if the engine compression is low, or if the hill is just too steep...down you go. That's why you should always park a manual transmission car in Reverse or First (the gears with the biggest gear ratios) AND apply the parking brake. Just doing one or the other isn't sufficient.
What difference would it make? You don't push the clutch in when you start your car?Originally posted by: spanky
damn, i put my car in gear twice this weekend when i parked and when i went to start the car again, i forgot about popping the car back into neutral. u can guess what happenedgood thing no one was parked anywhere near me.

And more importantly, you car will start without the clutch pushed in? Must be an old car.
You don't need to put the car in neutral to start it, just depress the clutch. All cars nowadays, and for a long time, have had to be started this way.
ZV, in many early cars, and I'm talking 50's-80's, it was emergency brake, not parking brake.Originally posted by: Zenmervolt

An automatic has a separate assembly (the parking pawl) to hold the car when the transmission is in park, this is _not_ the same as the normal gearing and it does not feed through to the engine at all. It is a physical bolt-type lock that prevents the transmission output shaft from spinning. On steep hills, if the transmission rests on this parking pawl, you can seriously strain the linkage when you shift out of park because of the friction against disengaging the pawl.
I agree that both the transmission and the parking brake should be used. However the parking brake itself should always be the primary means of holding the car.
Regarding the brakes being stronger than the transmission: If your car has the parking brake on the same axle as the drive wheels, fully set the brake and then try to drive away. Properly set, you cannot. In fact, this is a classic "shade tree" method for testing a clutch. If the engine stalls with the parking brake engaged, the clutch is good. If the clutch slips, it needs to be replaced. With an automatic, it doesn't matter how much gas you give the engine, it should not be able to break free from a properly set parking brake.
Again, I agree that using both is necessary, but you're bass-ackwards on which should be the primary method.
As for you use of the term "emergency brake" as support for your position, it's a poor choice since the proper term, ever since the introduction of the device, has been "parking brake". "Emergency brake" became popular as a term with the advent of automatic transmissions in the early 1950's because most people stopped using this brake for its intended purpose. The parking brake is designed specifically to hold the car in place when it is parked. That's its primary design function.

i know i do not need to put the car into neutral to start it. im saying that i forgot to put the car back into neutral from first (or reverse) after i started the car. usually, i leave the car in neutral when i park so i step on the clutch to start the car, then release the clutch and everything is ok. but since i have been experimenting with trying to put the car in gear while parked, i forget that i left the car in gear, so when i let the clutch go, the car jumps, then stalls.
i'm trying to change from leaving it in neutral to putting in gear, since it seems like a good idea, but its hard for me to change my parking/starting ritual.
That's pretty much everyting I've been saying, although you said it better. I was trying to not be so technical.Originally posted by: Vic
LOL. This last page is hilarious. Engine internals and transmissions undergo tremendous forces during acceleration, and people who claim automotive knowledge and experience are concerned about those components merely holding the weight of the vehicle while parked?? :laugh:
What do you think those components undergo while they are launching that weight forward? What do you think that one piston undergoes when you put the pedal to the metal? At every combustion cycle, that single combusting piston and rod assembly accelerates (not holds, accelerates) the entire weight of the vehicle. Ah, you're gonna break it by parking it in gear!! Hilarious.
Oh... and valves are only open during 2 of the 4 cycles (intake and exhaust) and closed during the other 2 cycles (compression and combustion). So even in a 4 cylinder, there will always and at all times be 2 pistons with valves closed (and 3 with a 6 cyl., 4 with a 8 cyl., etc.). It is impossible for this to be otherwise. One, for mechanical reasons, and two, because (when turned off) the engine will always stop at a point of greatest resistance to turning, not a "neutral" spot with the least resistance.

What's the point of leaving it in gear?
The car is at neutral when it's off. Well for mine it is at least. I can shift gears without pressing the clutch when my engine is off.

That is incorrect. The "car" is in gear if the transmission is in gear, period. Doesn't matter if the engine is running or not.Originally posted by: virtualgames0

My point is that the car stays in neutral while the engine is off no matter what position you put the stick in.

If the trans is in gear, the clutch is engaged (not depressed), then the car is effectively in "park".
Edit: And if these conditions exist, and you DON'T have the brake on too and you're on an incline, then you won't be able to shift the transmission out of gear without the car rolling.

OK, so why am I able to switch gears without pressing the clutch while my engine is off?![]()

If you are on flat ground, or if you have the e-brake engaged, then you can do it. Some vehicles have a pretty high rolling resistance, and I've seen vehicles that wouldn't roll in neutral on a slight incline.
If you park on any decent hill, and you don't have the e-brake on, and I'm assuming you don't have your foot on the brake...then if you take the trans out of gear, that car is going to roll.
edited: no such thing as a flat incline like I originally wrote![]()

I wonder why it is recommended to push the clutch in, when starting the car (even if it's in neutral)? I have a small 4-cylinder pickup, and I can start the engine without pushing the clutch in... so long as it's in neutral of course, and the parking brake is engaged. It's not old either, as it's a 2003 model.
