Dunno. I have read on other forums that this can wear out the clutch spring. I'll add to that at times I have done this (not counting high rpms where it is inevitable) you wind up with some amount of driveline lash, which I assume can't be great for the drivetrain, right? When the entire engine and trans pulls at their mounts, against bushings and the like, something has to be happening... Thoughts? Maybe it just feels that way. I'll never claim to know anything about the mechanical / engineering aspects of automobiles.

The whole idea of shifting fast is to get the clutch in and back out as quickly as possible. It doesn't matter how fast you push it in since you are disengaging the plates. There should be no major lash ever from pushing in the clutch and minimal if you are rev matching properly when letting it back out. Even when it does happen all is fine since that is exactly why the system is on bushings instead of bolted directly to the car. Not hurting a thing. The spring is not going to wear out any faster from a quick push than from a slow one. Unless of course as previously mentioned you happen to be Superman.

Well, I'm over 70 and don't have a Buick ......

Although, I am finding mrs humfrz's Saturn, Aura, more and more comfortable.

Yep, them 6 way powered, heated seats, automatic headlights, automatic transmission and V-6 engine are feeling gooooood .......

Not to worry, I'll cut you some slack, since you're from Tennessee ......

(since, with your gravel roads, all full of turns, going up and down mountains, you most likely don't get out of first gear all that often)

I noticed that sometimes when I shift, I have the car in neutral before the clutch is fully pressed in -- and then it is fully pressed in by the time I'm putting it into the next gear.

i.e., I push the clutch in simultaneously while putting the car into neutral, then by the time I'm putting it into gear, the clutch is fully depressed.

Is this damaging to the car and should I be more careful about having the clutch fully depressed before moving the shift knob at all?

Shifting into neutral isn't a big deal. You can shift to neutral without ever touching the clutch. Shifting from neutral into another gear is where the clutch becomes desirable. It's actually possible to downshift without using the clutch at all, as long as all the various RPMs line up at just the right moment. I wouldn't try it, personally. That's more of a dedicated auto racing thing.

You will hear and smell if you are abusing your transmission, don't worry about it.

smelling like burning brakes- you're damaging your clutch. Stop what you;'re doing knucklehead

Hearing a bad grind- oops, get it right the next time, you're chewing up your gears to some extent. (everyone else around you who heard it too)

Gram and Guy nailed it really. The clutch and transmission are not made of glass and take a pile of light misuse. They are designed to take hundreds of thousands of shifts from people that are not professional drivers and they do that very well.

There are three big don't does though:

Slip or ride the clutch. This is when you only have the clutch partly engaged and the face is just touching the flywheel. This will heat things up and can glaze the clutch disc pads or even blow things apart. You can do this for a couple of seconds (like starting on a hill) but anything prolonged or if it is just barely touching it can go bad fast. You will know you did it because you will create a smell that is like the very winds of hell have entered your car.

Grind gears. I am not talking about a brief "oops I let the clutch out too soon" buzz but a full on force the gears in there whether they like it or not grind. Clutch in until gear in or risk stripping gears and synchros. You will know you did it if your hair stands on end because it sounds like you have just started up a gravel crusher.

Downshift to too low a gear for the RPMs. Don't ever, ever, ever, downshift from one gear to another if you have high revs on the cars. This can over rev the engine and start busting up all kinds of very important parts. Stick to downshifting one gear at a time until you are comfortable and be very careful that you do not miss shift into the wrong gear. If you start to let the clutch out and your car screams at you get it back in fast! You may get away with this once or twice but if you keep doing it you will blow something up.

Those are the only three really bad things you can do and everything else will come with practice. The scariest part of learning to drive MT is the act of learning to drive MT. Don't overthink it and let things happen naturally and eventually you will realize you just drove someplace and never even thought about when to shift.
