Pre-loading shift, good or bad?

[Starmanut]

I've been looking at stuff about pre-loading the shifter before pulling in the clutch. I usually pre-load when upshifting and it seems to make the process smoother.
I heard in one discussion that it can cause wear on the shift forks. And some where they don't even use the clutch, just roll off the throttle for a sec.
Any of you guys that have done shift tear downs have any input on this?
Thanks!!

I wouldn't, it's much like holding the gear lever in your car. It does cause increased wear on the shift system.
Unless you're racing and every millisecond counts, not sure why there would be a need for it?

Not something that I ever heard of or did.

And that is why the DCT kind of transmission was created... not as much fun as manual transmission, but faster to change gears. "Pre loading" without a DCT, I don't think will be good, you will eat the gears

The DCT (Daul clutch transmission)
From what i have seen i would not want that trans in any thing i owned.
Of coarse most of the new transmissions r giving troubles.

too many extra parts in the same space = less material = weaker components
They are nice to use as it makes gear shifts quite smooth. Ok if you only keep a vehicle for the life of the warranty or you ride like Miss Marple on Sunday to church.

Preloading reduces my evets of missed second gear. It has become a habit and now I preload whenever I am accelerating hard. Don't want to miss a gear at 4000 rpm. It's not a lot of pressure. Just letting the trany know that a shift is coming.

In the meantime the shift fork is in continuous contact at high rpm...

one day you are going to miss second gear for good... don't do it..

It's not continuous pressure on the shifter. Perhaps a second or two. Missing that second sounds awful. You are saying that the preloading will damage the transmission? Sorry, my mechanic skills are in the lacking. I have no idea of how the transmission works.
