Do you downshift to slow the car/truck or just put in the clutch/shift to neutral and brake? I've seen reasons for either way, including putting wear on the drivetrain. Technically, putting the car in neutral (if you do that) and coasting/braking is illegal, as I understand it. So, by the law, you should downshift, I guess.
What do you people say? (If you care, I usually downshift while slowing 'cuz I get cool popping from the exhaust when I do it. :D.)

Downshifting is not good. It reverses the mesh of the gears causing unnesessary wear. Depressing the clutch and shifting to neutral doesn't hurt a thing. I simply depress the clutch and hold it in as I apply the brake without shifting. No problem either way.....tomato, tomahto.

Downshifting is GOOD. I've never heard of ordinary downshifting being some kind of danger to the car...unless the car is a POS, maybe. I've been doing it for 34 years and never hurt any clutch or tranny. Do you guys not downshift to make a turn?
There's nothing wrong with proper downshifting i.e., at sensible rpms. If downshifting makes the engine howl up to the redline and your passengers fly into the dashboard, you're probably overdoing it.
In gradual decelerations, the lower gear lets the engine do some braking (saving your brake pads), and it keeps ready power (and control) close at hand.
Coasting = less control, but also saves gas and is not dangerous IF you're ready to gear up in an instant. IOW: Rolling around in neutral for any significant distance is not a safe idea, so I usually keep the clutch in and the car in the proper gear just in case I need to power out of a jam or something.

Having said that, in most practical city-driving situations, you don't really have the time, or distance, or need to downshift, so coasting is OK.

As I told my daughters: When you REALLY need to stop now, forget everything but the brake!

PS - How does one "reverse the mesh" of the gears? :confused: I don't think that's really what you mean.

TU is right.

I downshift.

The only problem with a downshift is when one accidentally performs what is sometimes known as a "money shift". That is, instead of downshifting from 5th to 4th, you go from 5th to --oopsie-- 2nd. This overrevs the engine, floats valvesprings and perhaps causes Mr. Piston to meet Mr. Valve and make a frowny indention.

Bad thing.

But you've got to downshift.

I race and downshift ALL the time; I'm never in neutral. In commuter driving situations, you only want to coast when you're the only person on the road. If there's any other vehicle out there that you're not in control of, you need to be able to react and the only way to do that is to stay in a gear. As long as you know how to work your accelerator and clutch when shifting (either up or down) you will not hurt your tranny. Besides, hearing the roar of a jake-brakeing Hyundai is a beautiful thing. :-)

Downshifting IS NOT good. Don't be foolish. Brakes are meant to slow or stop an automobile, not the transmission. Depressing the clutch and coasting around a corner, or to a stop, before shifting is the correct procedure and is in no way dangerous.
When you use downshifting to slow a vehicle, you are "reversing" the intended mesh of the gears thus causing wear on the opposite sides of the teeth. This will eventually cause excessive gear lash (slop) which shortens the life of the gears.

OK, I understand what you intend by "reversing the mesh." But I disagree that proper downshifting creates a problem (and just about everything else). Proper downshifting just means getting in the right gear for the speed and rpms. A little engine-braking is incidental and no big deal; nobody is talkling about replacing the brakes with transmission.

Coasting is called "Georgia Overdrive" in truck-driver lingo.

I do what brat does, but with a Peterbilt. I'm not going to put any more wear and tear on an $8,000 transmission than I have to. Usually it goes like this...I'm cruising along in 9th or 10th gear, and a light turns red, I leave it in gear and start braking, then... just before or right at the moment the engine begins to lug, I put it in neutral. By this time I've slowed down a bunch. If the light stays red, I will have it in gear before I stop (low gear so I can go when it turns green).

I don't have the luxury of synchronizers like you guys do. If the rpm and speed aren't matched perfectly, it will grind when I try and put it into gear.

ps - I've heard that coasting too much in a car is bad, because your transmission won't get lubed.

Try coming off Sandia Peak with just your brakes. If you don't downshift into a lower gear and let the engine and transmission keep your speed down, there will be one of two effects:
1) You will gain too much speed and be unable to turn with the roadway thereby either crashing into the cliff wall or vaulting off the edge of the mountain, depending on the direction of the turn you missed; OR

2) Shortly before you get to the level road at the bottom of the mountain you will notice that you have no brakes left.

Similarly, if you downshift as you approach a stop, you will have more control over the car in the event some donkey in the next lane decides to merge. You will then have the choice of accelerating out of his path if that is the most efficient way to avoid being smacked.

Are you a tard?

Even in an automatic, the transmission downshifts when you slow down. You should absolutely downshift to help your vehicle slow down. This is not only common sense, it is also a safety issue. If your vehicle is always in the proper gear, you can always quickly accelerate out of trouble. If you put your manual into neutral, and come coasting up to a light, and a big-assed semi with Jerk behind the wheel is barrelling towards you, whatcha gonna do? That's right, become a Jerk pancake.

Comparing the downshifting of an automatic to that of a standard shows how clueless you are. When you downshift a standard, the transmission drives the engine instead of vice-versa. No such thing occurs when an automatic downshifts.
Downshifting is not sensible nor is it some kind of safety precaution. The proper procedure when approaching a turn or stop is to push in the clutch and keep it depressed until you need to accelerate again. You can still shift to a lower gear while holding the clutch in. This way all you need to do is release the clutch if you need to "accelerate out of trouble" as you put it.
Again, If you are going 60mph and downshift to lower gears to slow the vehicle, you are causing unnecessary gear wear. The brakes are for slowing and stopping, not the tranny. Anyone who claims to be saving brake pad wear by downshifting is a moron to say the least...or is someone who has never replaced a clutch or transmission.

Do you "downshift" when you drive an automatic? Example: If you are driving at 60mph and there is a stop ahead, do you shift the transmission out of "D" and into L3, L2, or L1 to slow the vehicle? That would be the equivalent to downshifting a standard.

I'm not a mechanic. I'm a driver.

I do not know where your advice comes from regarding the idea of keeping the clutch depressed through the apex of a turn. It's not merely contrary to what I've learned, but alien to my experience. I don't have my Bondurant materials handy, or I'd just quote them, but my memory is pretty clear that ol' Bob's driving instructions didn't include significant time in a turn with the clutch depressed. To the contrary, I remember a LOT of instruction on double-clutching, even with a synchro.

Do you "downshift" when you drive an automatic? Example: If you are driving at 60mph and there is a stop ahead, do you shift the transmission out of "D" and into L3, L2, or L1 to slow the vehicle? That would be the equivalent to downshifting a standard.
Can't wait to hear your answers.

Actually it's not the equivalent, if you do it right.

For starters we have the clutch and torque converter. When you downshift in a standard, if you're not bang shifting, you clutch and the transmission is disconnected from the engine. In an automatic the car is in drive and the torque converter is spinning. You can't go from drive, to neutral, and down to L3 in an automatic. The link is still connected as you make that "downshift". In a standard when you clutch and connect the engine back to the transmission, you're already in gear, hopefully.

Now as you shift through an automatic, the torque converter is spinning and when the gear ingages it gets extra wear as it hits hard. The same can be said about bang shifting in a standard. Example, try shifting in a standard without the clutch.

To the orignal question though, it's not wrong or bad to downshift in a standard. To the people saying it's wrong, you must have a bad transmission to not be able to downshift in it. The only thing I can say is to not downshift and "skip" a gear. If you do, at least go through the motion to keep the synchronizers in line.

The original question posted by OUDoc pertained to SLOWING a vehicle by downshifting. Let's define how you downshift to slow a car:
While driving at a higher speed, you depress the clutch and shift to a lower gear. As you release the clutch the tranny "drives" the engine to a higher rpm thus creating the resistance that slows the car. As the car slows you repeat the steps each time shifting to a lower gear.

You can't go from drive, to neutral, and down to L3 in an automatic. The link is still connected as you make that "downshift". In a standard when you clutch and connect the engine back to the transmission, you're already in gear, hopefully.
Of course you can manually downshift an auotmatic. Try it and see. It IS the closest thing to downshifting a standard to slow a vehicle. Don't forget, Others here started saying that downshifting a standard is the same thing an automatic does on its own. The reason that notion is false is because an automatic transmission is connected to the engine via the torque converter. Torque converters rely on engine rpm to create the static friction that transfers power. Therefore when you slow down while driving an automatic, whether you apply the brakes or you simply let off the accelerator, The engine rpm drops thus releasing the static friction between the torque converter and tranny. Thats why the engine doesn't die while an automatic is stopped while still in drive.
The power transfer from an automatic is a hydraulic one via the torque converter as opposed to a standards being a simple clutch that is positively engaged as long as the pedal is released regardless of engine rpm.

Now as you shift through an automatic, the torque converter is spinning and when the gear ingages it gets extra wear as it hits hard. The same can be said about bang shifting in a standard. Example, try shifting in a standard without the clutch.
You lost me on that one. I don't know about the whole "bang shifting" thing. The topic was downshifting, not shifting without the use of the clutch.
There are no "gears hitting hard" as an automatic shifts normally.

To the orignal question though, it's not wrong or bad to downshift in a standard. To the people saying it's wrong, you must have a bad transmission to not be able to downshift in it. The only thing I can say is to not downshift and "skip" a gear. If you do, at least go through the motion to keep the synchronizers in line.Nobody said they were not able to downshift. The controversy is whether or not it creates additional wear on a transmission, which it does.

2000, I think.

We've had a couple of board resets, though.

He's right, though. Banking does get kinda boring at times.
