And rev-matching is NOT shifting without the clutch.

Yea, I always thought rev matching was exactly that.. Matching revs while downshifting.

Shifting without a clutch I always called "oh shit my clutch just blew out on me"

I don't recommend it but here you go...

How to Drive a Manual Transmission Vehicle Without Using the Clutch

You should be rev-matching your down shifts anyway, but while using your clutch.

All BS.

Rev-matching SAVES the synchros. And rev-matching is NOT shifting without the clutch.

As stated above:

Rev-matching is the proper way to downshift an MTX transmission. It prevents excessive wear on the transmission and clutch.

Sheesh, come on guys. How long have we been driving??

Huh. I always kinda thought it was dumb not to rev-match on the downshift. Nobody ever told me to, I just kinda figured it out on my own. :biggrin:

We will alway's be able to buy a clutch for our cars at a reasonable price.
However, every day there is one less MTX out there and we can buy NO new "hard" parts for them.

USE THE CLUTCH, SAVE THE TRANNY!;)

If you downshift when slowing down.....FAIL

If you push the clutch in when coming to a stop....FAIL

Rev-matching is really only used for racing. Yes u can do it on the street but its rarley ever needed.

This all comes naturally as u learn to drive a stick IMO. It all about when everything matches up. So anyone who never tried. go 45 mph throw in neutal. Rev/hold to 4k and right about 39-41 mph 2nd gear should just engage. Thats rev-matching, u r doing the sycro's job.

I throw the car in N as I'm slowing down to a stop light and I leave it there until it's ready to change. There have been arguments back and forth about this. Some think that it's dangerous if you're not in a gear in case you have to move quickly. Others think it saves the clutch/TOB. I do it to decrease wear, plus my left leg starts to bother me at those really long lights if I hold the clutch in.

I always use my clutch. This is the first MTX car I've owned, so I'm not familiar with fancy racing shifting or anything. I did notice that when I drove a Gen 2 MTX that the clutch was very smooth and you could feather the pedal easily for a smooth take-off. My 90's clutch is grabby as **** and if you don't get it just right you'll over-rev or bog/stall the engine. I did the 4th gear and go slow trick to see if it was slipping and it didn't. Maybe I just have a ****** clutch; I don't know. I hate the way it drives compared to the 95 I drove.

Your clutch is wearing out.

I've been driving manual tranny cars since 1966, and, even with abuse, I get lotsa life out of a clutch.

The whole trick is to have the clutch engagements/disengaements as short as possible. Which includes not leaving the clutch disengaged to wear out the TOB.

Now I've heard of rev matching on downshifts also keeps shock on the driveline and clutch to a minimum, since you're not draggin the clutch on the downshift, where if you were to just smack the clutch pedal like in an upshift, it'd really take it's toll on motor/tranny mounts.


Did that even make sense?

Yes it made plenty of sense and that is exactly why I rev-match all of my downshifts.

Yes, that makes sense, and it's true. Matching revs on downshifts is easier on the equipment for the reason you mention.

I rev-match every downshift. Anybody who does or plans on doing any road course driving can learn to heel-toe (or just rev-match) while driving on the street, and I think that's the best place to learn it. Getting it be second nature on the street makes it automatic on the track, and since it's easier on the equipment there's not really any downside, IMHO.

If you never plan on any track driving then there's very limited benefit, but awareness doesn't hurt, either.

Rev-matching SAVES the synchros. And rev-matching is NOT shifting without the clutch.

Granted, it's not needed as much with synchronized trannies, but it will still save the synchros in the long haul.

It's also referred to as "Heel and Toe" shifting. Basically, the left half of your right foot is on the brake, and between shifts, you shift to neutral, let the clutch up, and blip the throttle with the right half of your right foot. Then shift to your gear. Some folks do it with the ball of the foot on the brake, and blip the throttle with their heel. It works best on a car where the brake pedal and gas pedal are about the same height.

It is still a valuable technique for driving an MTX SHO on the track where you may be downshifting from 3rd or 4th to 1st or 2nd for a corner. On an older tranny, it won't always want to go into gear with worn synchros. I never practiced it enough to get good at it, but i have just done the technique to rev-match in neutral on certain tracks where I would downshift.

Bingo! /thread
