Yes, but I don't pull the clutch out completely since my reverse gear is a straight gear or something, maybe the wrong term?

Reverse gears are typically straight-cut and non-synchronized (this saves on machining costs and reduces complexity without any loos of function since helical-cut and synchronized gears are only helpful when shifting while moving and reverse is almost never engaged with the vehicle in motion). However, there is absolutely no reason to slip the clutch because of this, you should engage the clutch fully or you are severely shortening its life.

ahhh....so that why reverse gears are so noisy then. its a straight cut.

<---used to work for a transmission company and should have thought of that.

What do you mean by slipping the clutch?

theres 3 ways to have a clutch

engaged (pedal to the floor)
slipping/superslipping/extremeslipping/riding (pedal out half way, or foot lightly on pedal)
disengaged (pedal out all the way, foot off)

slipping is used when on a hill to keep from rolling, slip the clutch a lil to get some force on the tires, or to slowly accelerate in first slowly release the pedal to keep from being jerky, same goes for most gears, you lightly slip it, but you dont just keep the pedal half way down you either fully engage it and coast, or you fully disengage it and keep enough gas to keep from stalling

I always thought engaged = pedal released & disengaged = pedal to the floor.

i might be wrong, but i always thought that you engage the clutch, to disengage the gear.

engaged = no contact with flywheel, ie "clutching"
disengaged = contact with flywheel, motor turning tranny.

Hm. I guess you could look at it either way..when I think engaged/disengaged, I think disc/flywheel..

Edit: Thanks for clarifying, spidey07 - I'm apparently thinking backwards.

Gotcha. Just got my permit (just now) and I haven't driven yet... so slipping is bad for the clutch but why is engaging it (pedal to the floor) NOT bad for the clutch?

my reverse is such a low hear I can move with using the gas

Reverse is normally the lowest ratio on a car.

But one is an idiot not to use the gas pedal when reversing. Sorry to be harsh, but if one thinks that you should just use the clutch to control your speed with motor idle one needs to have one's license taken away.

[ThisIsMatt]

This thread is hilarious. Any thread about cars gets the usual "hand over your man card if you get/have an automatic," but it's obvious that a ton of people have no clue how to drive with a manual transmission.

Of course you can use the accelerator in reverse gear, and most cars will stall if you don't (assuming not on auto choke right after starting a cold engine). Just think of it as first gear, but moving you backwards.

most ppl can...

slipping is bad for the clutch because it creates extra friction due to the clutch and flywheel spinning against each other almost, basically can heat the clutch up and warp it, or can just slowly destroy the clutch due to the friction.

and spidey07, sometimes to get out of my garage ill let the clutch out 1/2 way slowly, get enough speed just from that and re-engage the clutch and just coast, some effect, just all that i need, now if i back all the way out of my driveway, then i will let the clutch all the way out.

Intuition tells me it would stall.

[cjgallen]

EXAMPLE:
1st gear tops out at 20mph
Reverse tops out at 5mph

When you accelerate in 1st, you hear the revs go up, and you also feel the car speed up, all the way to 20mph.
When you accelerate in reverse, you hear the revs go up, but since it tops out at 5mph, it won't SEEM like the car is getting faster, because the gear ratio makes the speed range very narrow.

I think that's what the OP is confused about, right?

That's ass-backwards.

Engaged means that the clutch is coupling the transmission input shaft with the flywheel. Disengaged means that the clutch is not making contact with the flywheel and the engine can spin free of the drivetrain.

I can go a lot faster than 5mph in reverse..heh..from my experience, they seem to be fairly close to 1st gear (as far as gear ratio goes).

Holding the clutch pedal down for long periods of time (ie at traffic lights, etc) puts increased wear on the throwout bearing as well..

With the pedal to the floor the clutch is completely pulled away from the flywheel and not touching it at all, this imposes zero wear on the clutch. It does slightly wear the take-out bearing but this bearing is designed to take that wear and can easily outlive the clutch (though the take-out bearing is replaced during any competant clutch replacement).

Immaterial. The amount of wear is so small that there is no tangible effect on the life of the bearing unless you're using an absurdly heavy pressure plate.

Regarding gear ratios: On my 944, first and reverse are identical at 3.500:1.

I haven't lost a TOB before a clutch yet, but my uncle's Dakota did, and a friend's GMC Sonoma literally tore one up (we pulled it out in pieces)..who knows why that happened, though.

I leave mine in neutral rather than keep the pedal down..much more comfortable (ACT heavy duty pressure plate). I did drive my cousin's Sunfire, though..there's almost no resistance when the pedal is to the floor.

ok, i guess ill post the next manual car thread...

heh, while we're at it on the throw-out bearing. I have never had to replace a clutch, and I drive hard as a mo-fo. 130K plus on cars and still haven't had to replace a clutch.

Now I did have a problem with a clutch/tranny one-time and my mechanic told me it was because I caught 2nd gear too hard...basically dumping it in second. Sure is fun though.

The car just abunch of mods done to it which means it needs to be tuned. He shouldnt be driving it like that, but he did. Im sure hes a good sticker, but i bet even you wouldnt stop that car from stalling untuned. Also, hes shifting slow so it doesnt blow that untuned engine.
