The driver on this pass is actually my transmission guy.[clutchless shifting]
You can pm him to learn more about the trans. (tomdcarguy)
Your trans can be modified to allow you to drive the same way with the right supporting parts.
You can gain significant et by shifting this way. The less experience you have the more you will gain in general IMO.

Your friend in an idiot. Clutchless shifting can be done if slow and deliberate. Speed/power shifting without the use of a clutch is inviting your traniny to grenade..........quickly. Ask him to demonstrate, on his car.

It's a specially built m6 transmission, that can be done to his transmission as easy as having the trans freshened up/rebuilt.
I would expect most people would find it interesting and it was on topic.
I don't know what we would do without you clarifying an already clear point.
To anyone who might be interested, I will reiterate my initial point:
Cluthless shifting, with the proper trans and supporting mods can significantly reduce et.
This transmission rebuild can be done to your c5/c6, using your existing trans.

I didn't say it was a stock transmission. I guess you missed that part of my post.

Rob does the trans have any negative characteristics when being used for a daily driver? Is this something that should only be considered for a track car?

All bashing aside (come on guys)...
You need a clutch to shift a modern transmission akin to the T-56 and a 6060. If you traction isn't an issue, then you can keep the throttle WOT (and if you have a TT setup, then this is the ONLY way to shift if you have a manual tranny) and use minimal clutch, but clutch actuation is required for a transmission to live.

No buddy.
It's easy to drive on the street but takes a few days to get the hang of it. If you do it right it clicks in perfectly smooth and uneventful.
It's certainly not for everyone and most people probably wouldn't consider it for a dd. I hear that (18 wheeler)truck drivers use the clutch just to get started and go clutchless after that. You basically have to retrain yourself. I actually enjoy it on the street. I also like to have the option of using the clutch or not using it. It might take a person whose really into performance driving. I bet a very experienced RR guy/gal would kick *** on a road course with this setup.
We did this as an experiment to see if it would work in the c5/c6 and it does. On the strip you need to be careful that everything is working together if you would try and go clutchless.
I havent taken a pass clutchless on the strip yet but it will reduce et.

Attention: This ? pertains to a modified t56 m6 not the factory stock trans.

I used to do it as "practice" just to prove I could. Then on my '64 vert the throwout pivot broke and I had to do it to get the car home. The practice helped to avoid some real grinding. I don't recommend though it as a steady diet.
BTW - the throwout pivot broke at the block and I had to use "easy outs" to get it out and replaced.

Cutting off syncros and welding on dog rings has been done in the past. This is old school and will require lots of work to keep good for a long time. Think about how many shifts during a lap at your average road race track. This mod is pro racer stuff and shouldn't be played around with unless the person knows what the actual cost. Just make sure your guy spends more time telling and not selling.

I know because I have this setup in my car now. It has lasted over a year with some nasty launches(100 passes) but my car is setup right for the strip.
It's certainly not for everyone and I wouldn't recommend it for the average racer.(roadrace or dragstrip).
But the point I was trying to make is that I have very little experience with stick cars. My first stick ever was this car I bought in 03 and I managed to learn how to drive the car anywhere smoothly. A very experience roadcourse driver would do awesome with this trans, I have no doubt.
Again, not for the average guy but an option for some who are really into racing. I felt it was pertinent to the original posters question as well.
Anyone who is local can go for a ride with me to see what it's like.

If you shift without using the clutch, be sure to have a bog box in the back of your car. Cause sooner or later you will need it to pick up the pieces.
