When stopped are you supposed to put the car in neutral and release the clutch and just use the brake? I used to have a 5 spd and at stops I would have the clutch pushed down all the way and have the truck in first gear ready to accelerate. That truck was brand new when I bought it and I sold it 3 years later so I don't know if I did any damage to the clutch. I'm asking because I read somewhere that you are not supposed to keep the clutch pushed down at stops?

i leave it in neutral with the brake pressed. it was confirmed long ago that holding down the clutch for a long period of time (15+ sec) causes the wear on bearings on my thread.

my question in for this thread:
is it better to overshift or undershift? example: When I'm driving about 40 mph, the RPM is perfectly @ 3000 in 3rd gear and 2000 if it was in 4th.

at 3000, the engine is loud in my ears (but then again im really anal about cars being quiet) so I want to go into 4th gear.
at 2000, the engine has that Slight 'struggling' feeling but is nice and quite. but i wonder if this is good for the car.

educate me on this.

Yeah thats what i do... even though i'm told not to do that because the car won't be in gear immediately in case i have to avoid something.

I'd put the car into neutral. I heard that with cable trannies, keeping your foot down on the clutch will cause it to wear down.

But , doesn't it feel awkward with your foot down the whole time?

You press the clutch only when changing gears(up or down), pressing on the clucth like a brake pad when coming to a stop is harmful, not so much in the most devastating way however. Didn't you brake with the engine without using the brake pad?; clutch, 4, release, clutch, 3, release, clutch, 2, release, clutch, 1, clutch neutral.

This must be why the boy racers take longer to move than old ladies when the light turns green.

No, I would just put the car in neutral and use the brake when slowing down. I never had problems with the truck and I drove it about 30,000 miles including cross country and through the Colorado rockies.

I hate people who do that. Just engage the clutch and use the brakes... so much easier.

i NEVER engine-brake. I think it's bad in a incremental way or the other. I just neutral + brake, or reenter into shift if I need to accelerate again.

Leave it in 4th unless you plan to accelerate.

I'd wager a guess that there's more stress on the engine and tranny when it's struggling (think of the combustion occuring trying to force down a piston that doesn't want to move, rather than spinning easily along at 3,000RPM). My friend shifts like you, but a lot of times I think he shifts WAY too early...makes my skin crawl listening to his engine.

Just leave it in gear with the clutch pedal down. Yes it wears the throw-out bearing. No this is not a concern because the throw-out bearing is replaced every time the clutch is replaced and the wear from idling on the throw-out bearing is not nearly significant enough considering the frequency with which the bearing is replaced.

Here's an example of when I was glad I didn't have the car in gear. True story. I had just gotten my manual car, and had only learned to drive it a few days earlier. So the phrase "if you can't find 'em, grind 'em" was heard often in my car. I had stopped at an intersection on a hill....a new manual driver's nightmare. When the light turned green, I knew I didn't have much time to get it in gear before rolling backwards. Of course, I messed up and killed the car. As I was restarting, some 3 seconds later, a pickup zooms through the intersection. It would have struck me on the left side, and I would have been killed for sure.

Not advice for keeping it in neutral, but just a story.

Wrong. Leave the engine in gear when slowing but do not downshift. I.e., if you are braking from 60 mph, leave the car in 5th with the clutch engaged and brake until the engine speed reaches about 1,000 RPM, then disengage the clutch and continue to a stop using just the brakes. When you stop, engage first and keep the clutch disengaged.

What you just said to do is what the original question is about, and technically you'd be wrong if you're looking for the least-wear solution, which would be to let the clutch back out while stopped in neutral as to not wear the bearings any more than necessary.

What is the big concern about the bearrings anyway? Oh no it might wear out a bearring omg! You'd rather wear your brakes out? If you know how to drive, and you keep your car in good shape - either way is just fine. It really is just the 'excessive' use and wear-n-tear that takes a toll on a car. I always leave my car in first at stops and I've never had problems.

Actually... the throw-out bearring in my Camaro is worn out - I can hear the noise when I don't have the clutch pressed down. So now I just ride the clutch when I'm driving at low speeds and can hear the noise - and keep the clutch pressed down when I'm at a stop. My clutch still works just fine. But unless I'm planning on doing burns every day I doubt I'll have a problem with my clutch any time soon, despite the throw-out bearring being worn. So I think I'd rather that happen than have to replace my brakes more often. which reminds me, my brakes are worn too .. damn. :p

The bearing gets replaced with the clutch! It doesn't matter if you put a little more wear on it because the replacement interval isn't long enough for that extra wear to surface in any detectable way! I give up.

Because, when you're sitting behind some moron at a stoplight, and it changes to green, and he's still dicking around putting it in gear, ya wonder, why the fvck did you have it in neutral in the first place? :disgust:
