Shifting a car manual

[toothfangclaw]

Am I safe to speed/rpm match shift my 87 Acura Integra like you can with big trucks? I used to drive a 26k gvw  IH truck with the ”6+ 1” manual trans. The break from the clutch would be welcomed at times. I just don't want to grenada my trans. Lol

Thanks.

ive driven all kinds of things that way, not just big trucks.  ive done it with everything right down to a nissan sentra.  give it a shot, cant hurt

Give it a try. Doubt you will grenade anything. Most manual trannies can be shifted that way.
If it doesnt work, push the clutch in and put it in gear.

Be careful--those gears are made of rice paper!

Bwahaha! it's amazing how much mpg you pick up by using rice paper for gears! Who says american steel is the only way to go? Lolol

Wouldn't that be somewhat hard on synchros?

Not if you let the rpm line the gears up for you. If you force it into the next gear it's hard on everything.

Ive tried like crazy to get my 4 runner to do it but it just wont, Ive done it in a lot of other rigs, diesels, vw's, etc..

I found it more difficult to do with newer transmission.  Some of those late 70's and early 80's were easier to do, so 87 would be about the time they changed to rice paper synchros over the prior, which were more a long the lines of brass.

The other thing to keep in mind is that when you do it with a truck you are changing from 600-1800 rpms. vs an Acura that is between 800-3500 rpms. So it is more difficult to get the rpms to line up due the disparity in the range of rpms. 

Purely again my experience.

For a while when I was younger, I drove a 1947 International with a non-syncro transmission.  The transmissions these days have such nice syncromesh transmissions and hydraulic clutches, that I can't complain about pushing in a clutch.
