If you do save your money for a rebuild. I wouldnt think about doing this method of shifting. Use the clutch keep it floored and shift this will also be hard on parts.

Unless you want to start going through transmissions faster than clutches I do not recommend that

You can shift your tranny at any rpm without a clutch. The key is to match the engine rpms with the rpm the clutch is spinning.

I use to drive my 1992 3000gt vr4 without even using the clutch, same with my 94 Miata M edition I had. Only time I had to use it was when I was at a stop.

from my understanding you arent supposed to do it with transmissions with syncros which is what we have in our transmissions, so like others have said dont do it. just practice shifting and actually hitting the gears and not missing.

Pro shifted and faceplated transmissions don't have syncros. I wouldn't reccomend trying to shift without using the clutch, and even on faceplated t56's shifting without a clutch is near impossible under full power.

Any manual gearbox can be shifted without the clutch. Whenever you are changing from a lower gear to a higher gear it's easy because the engine is turning faster then the wheels. Just let the RPM's fall to just before the speeds are matched and slip the gear in.

Downshifting is a different skill because you have to blip the throttle to match the engine revs to the wheels.

What the hell are you doing anyway? Just use the clutch.

What you describe is a full powershift, and although it sounds so fun your drivetrain won't be laughing....

Shifting is, once you've understood the basics, a personal preference of the balance between drivetrain life and speed. In a normal "street" shift, you either pop the gear out by lifting off the throttle or clutch in, allow the revs to fall to the perfect point as you slide the gear in with or without the clutch and then continue with power. It is smooth. It is also slow.

In order to negate this, during an upshift in aggressive conditions you will want to get the gear in with the rpms a little higher than "perfect". This will give a little boost(can't describe it another way), you do not have to wait as long for the rpms to fall, and you will be quicker. But it has many detractors: increased wear, increased difficulty, not as smooth, etc. (This is also why I said "Full Powershift" above, because this is essentially a powershift of its own, but it does not stray nearly as far from the rpm difference of the wheels and engine.)

Basically, the further you go rpm-wise from a perfect mate of engine to wheel speed, the more you run the risk of missing a gear and the faster you wear out your drivetrain.

(NOTE that if you don't use the clutch from neut->gear you will always have a little "jolt", that is more wear for your trans and the pros recommend you "jab" the clutch to the engagement zone to soften this)

Hope this helps.

Replace your M6 with an A4. After doing this, you will no longer need to use a clutch to shift.

Or go with a powerglide tranny and use pedals. Ir you can do what im doing and learn to powershift. Then once I learn im rebuilding tranny and putting on my monster clutch. But it is possible. My uncles do it on their semis. He did it on my car as well. I can't do it tho

you either need practice, or it's actually a clutch disengagement issue causing you to not be able to get into gear at high rpms

Oh I figured he meant for example shifting to 4th instead of second because h was going fast
