Maybe he's going 20 MPH in 6th gear and decided he's doing it wrong? Lol.

I've never done it but imagine cruising at 60 mph in 6th and you suddenly need to quickly overtake or avoid an accident or something. Downshift to 3rd to get the most kick...I guess. But i'm not experienced it's just my theory

I'm gonna get flamed for this, but I only downshift by rev-matching. I'm new to driving manuals, so I still don't have the clutch control to let it out slow enough to downshift without blipping the throttle in-between. I'm learning now how to, but yeah, see below for why I downshift rev match from 6th -> 3rd.

Where I'm at in Texas, I use highways whose exits lead to turnarounds fairly quickly, so I exit the ramp at ~70mph, cruise in 6th to the turnaround, downshift to 3rd or 4th before it, and putz my way through. Never really was one to engine brake going through all the gears.

If I am just cruising along at 55MPH trying to get good gas mileage, I'll be in 6th at 2500 RPM.

If I suddenly see I need to pull off a pass, I can down shift to 3rd which would be 4900 RPM just past the torque dip.
If you stomp it there you will soon find yourself upshifting again soon.

Okay. I guess it just seemed like a bigger RPM jump than it is.

If you're referring to what I was saying about the stepped downshift, It's not a matter of engine braking, it's literally clutch disengage, 6-5-4-3, rev-match, clutch engage.

It's just so the 3rd gear syncro doesn't have to do all the work of spooling up the input and counter shafts.

That technique is definitely not controversial.

Anything on that first gear lockout? I looked - didn't find anything.

No, you won't get flamed. The people getting flamed are the ones telling everyone to double-clutch all over the place. Rev-matching is good practice if only because it makes for a much smoother ride, and makes you look more bad-ass (and can be handy on the track.)

Rev matching is what you are SUPPOSED to do. Any modern automatic gearbox car rev-matches for you, and there are even manual vehicles (such as the 370Z) that will rev-match for you. Rev-matching is the proper technique.

And it also reduces wear on your clutch.

The new Corvette has active rev matching. If you downshift, it will match the revs for you so that you don't have to blip the throttle. Which made me wonder, if you're accustomed to blipping the throttle and blip it anyway, does it rev match your rev match?

[Stang70Fastback]

When I drove the 370Z I actually never thought to mess with the auto rev-match... a failure on my part, clearly.

In the pic above you posted.
What is the "First shift restrict ball" for?
I would assume to restrict you from going into 1st? From where?
1st is the only gear that has one.

Is that the same diagram to which you were referring? I don't know what it does and I don't like making assumptions.

What I am interested in is actually learning something new and correcting misunderstanding should any exist.

I double-clutch between rev-matches.

Question:
Its bad if i press the clutch→ blip throttle→downshift→ realese clutch all with fluid motion?
