This place would probably have all you need. I almost went this route swapping out the 4+3

If I can put this together in my head in such a way that makes sense, a call to Dino was in order.
Still haven't put it together yet though... I need the weight of the TKX vs. the ZF, I don't want the thing to sound like a bucket full of bolts at idle, it has to be able to survive the power (500hp small block PLUS boost... So, figure 600-650 crank) parts have to be available and the whole thing has to make sense financially.
Working on it mentally right here, right now!!!

thanks for putting all that together. I'm definitely convinced to keep the 6 speed. I'm very nice to trans, I've never hurt one. Most likely do to the cost of tires and a bad leg that hurts me more than the car doing speed shifts.

notcy shifting, grinding gears, at WOT the lever would jam and not move into the next gear.
when i drained the fluid, there was all kinds of bronze flecks and i only had the fluid in there 1 week
if someone has put that crappy fluid in there, that may be why you are unhappy with it.
that said, even with syncromesh, its never gonna be like butter

Not happening.Come on man....is this stuff for real? What you CAN do, is work on your shifting until you get it to the closest point to 0.00 seconds, that is humanly possible. In my experience, that is ~.25 seconds and that is not even close to how fast most any DCT can shift. The problem is the clutch pedal pump; it's a two step, reciprocating maneuver, during which, the engine is inevitably disconnected from the drivetrain for a period of time. No matter how small the time...it's time.
In comparison, with the DCT, two gears are always engaged; the one that you're accelerating in, and the next one. The "shift" is a simple disengaging of one clutch and the simultaneous engagement of the other. Timed/tuned right, there is NO point, at which one or both of the clutches are not providing tq into the drivetrain from the engine. The actual "shift" may take a period of time to complete and reach full lock up in the next gear/clutch....but the system can be tuned such that there is always tq into the drivetrain, even during a shift....very much like any automatic transmission.
The weight of the ZF6 is a drawback to the ZF6....but a natural consequence of a "brick **** house". It weighs ~145 lbs. and thus is one of, if not the heaviest 6 speed car transmissions that I am aware of.

I happen to love driving. I love shifting and running the back roads. you know, push in a clutch, push the shifter, toe heal the brake and gas. Its a wonderful dance. I guess some people just don't get it.
and as I point out to anyone that races, that great thing that you think makes you faster, also makes the guy in front of you faster too. so as its been pointed out, you would do better to learn to drive better.

I drive a manual. I love my manual. But I'm not a silly git like diz who thinks the C8 is inferior to a car from 30 years ago.

its inferior when it come to the feel of driving. it just one more step removing you from being invoked in the driving experience.
my guess would be that the new C8 is the next 1984. could be wrong. time will tell.

I love ^this^! Well said! "The dance", indeed....it can be one of the most rewarding things you can master. I'd add, the sound of the exhaust + the feel of the clutch release...going up or down, when done masterfully.

well, if I wanted to go faster, I could install a 6XD Sequential Gearbox in my 1995. then I could shift just as fast, oh boy. there you go. Like I said, I had a bad leg, So I've look into it. drove some car with semi autos. they never work quite like you would want them too. I guess there are just way to many people out there that think a computer work better than a brain.

That 6XD is still a manual gearbox and you cannot shift it nearly as fast as an DSG or even a semi-automated single-clutch manual. It's faster than a synchonized production-car manual, but it's still nothing like a robot.

If it were in the budget, I very well might. It's an amazing car. But that's beside the point - whether or not I want a car with a DCT has nothing to do with the fact that the C8 DCT is way, way faster than even these fast dog-ring, sequential manuals. FWIW, my 2020 1LE that replaced my 96 C4 is a manual.

In that turd, you could totally FEEL, three separate steps; Clutch in, the shift, clutch out. In my car, a good shift feels like a two step ordeal; paus-BAM!
BMW claims .08 seconds....I don't believe it. No way. I've measured ~.2 in my own car. I'd like to measure the BMW. Ferrari claimed a more leisurely .15 for their SMG. IDK...but I'm not impressed by those at all. I believe that a human can out shift them and it's already been proven that the stick car out accelerates the SMG car. So....
Back to the 6XD, that is a dog style, clutchless shifting trans, right? I can't see why that couldn't execute a complete shift, lock up to lock up, as fast as a DCT. It's a one-motion affair, and engagement is instantaneous.
