Sequential kit for the T56's

Just thought I would pass this info along.

Apparently fits the stock case. Info Blatantly stolen from LS1tech.

Awesome!!!! Assuming it works in the T56 magnum cases.

That's pretty sweet! That is if you've got an extra 20K laying around.

There's also a guy on PT working on this. I think he uses something similar to a Mastershift (?) acutuator to shift. Not yet a fan of that system.

Interesting! But if I'm being honest, I don't fully understand what a sequential shifter does. Do you still push in your clutch?

I just got my six shooter sequential t56 from MTI. You don't use the clutch for shifting. Essentially, it's like a motorcycle trans. Use the clutch to get started and that's it. You don't have to lift the accelerator on up shifts and it auto blips the throttle on downshifts.

The trans is going into a race car though, not a street car. I'm not sure the expense would be worth it for a street car but for a race car, it is actually pretty cheap. Purpose built sequential racing transmissions like an EMCO can cost $40k-$60k.

It would be interesting to see how much improvement it would have in lap times vs more adding more horsepower.

Greg here's my opinion - If I'm driving on the street do I really need a clutchless sequential shift? Yeah it'd be cool but not sure I could justify it. OTOH if I'm racing I want the fastest, easiest and most reliable I can get. If I'm in a vette I'm almost limited to the MTI option. Other conventional motor/trans set ups have the ability to do clutchless, sequential shifts. Then it goes back to cost, reliability and fitment. Not sure a T56 set up meets that criteria yet...

Horsepower isn't always your friend on the racetrack. I'd rather have a well handling 400+ HP race car than an ill handling 600+ HP race car.

With that being said, the car that my trans is going into weighs 2050lbs with 585rwhp.

On a road course you can shift 20 times per lap or more depending on the car and track. If you can pick up .1 second per shift, that equals 2+ seconds per lap, which is usually the difference between the front runners and mid packers.

Also, if you're spending $20k+ on your trans, the odds are pretty good you aren't lacking in the motor department :)

I agree about not needing clutchless sequential trans for street use, unless someone come sup with one for less than $10k. There is no question that they are cool but no real reason to spend the money unless you are racing in my opinion.

But there are definitely other options for Vette owners. EMCO makes a direct replacement that is awesome but its quite a bit more expensive than the MTI trans.

Hopefully the MTI trans will hold up as I believe I have one of the first customer trans out there but since my car is so much lighter than a Vette, it won't have as much stress on it.
