Sequential gearbox

I wish the SS and ZL1 1LE packages had an option for one of these sequential gearboxes! Very fast shifting, still keeps the driver involved/in control, and it would be nearly impossible to miss a shift which could over-rev and grenade your engine/transmission on certain missed downshifts with an H pattern manual (like accidentaly going from 5th to 1st instead of 3rd at high speed).

For a street car.. the noise and cost is a non starter. They are nice on track though.

DCT technology (computer shifted manual) is readily available in the German market on every level of car from 4 door hatchbacks to high end Porsches since the early 2000s. The American car companies never really took to the technology (Ford tried, went with dry clutches vs wet and had some horrific results)

Had a Golf TDI as a daily with it, worked excellent. Fell in love how fast it shifted and how it barely dropped RPM between shifts.

Currently have a Honda motorcycle with one and would never go back to a standard trans.

Actually, there is a company in Australia that makes a conversion kit to give you what you are looking for:

I assume he meant a real sequential trans (more like your bike) than a DCT..

I have it on my Leon-FR (DSG) - It does shift lightning fast (especially with the TVS software on it ), HOWEVER, it is a fragile mechanism - Especially since its a Dry-Clutch system - so the torque handling is limited to 300 lb
Still OK for a speedy daily commuter on this 1.8 Liter engine.

Went to check their website for pricing but looks like someone didn't pay the internet bill - https://www.bremershifters.com/

Found on another forum they're asking around $2400ish. Not bad if you've already got Tremec box. Wouldn't ever use that for the street though, that's a bit much.

Also looks like from the videos I'm seeing you still have to depress the clutch on these shifters. I think the Lotus video that was posted originally was a system that doesn't require you to depress the clutch which is substantially quicker. That $2400 price tag seems a lot higher now. If you want a clutchless system here's a good lead to a company I'm aware of - https://www.ppgearbox.com/

VW uses a wet clutch system - First came on the R32 Golf and there are many that run this setup well over 500hp. The 7 speed version on the Golf R is the same one used by Porsche and Lamborghini.

The VW / Porsche DSG transmission is basically a large motorcycle transmission - you can even service the clutches on the side like a wet clutch on a motorcycle

Cool! Thanks for the info. I had no idea that was even an option. While you would still need to use the clutch with that it would probably still be significantly quicker at shifting and eliminate missed shifts. Would probably be nearly as quick as a true sequential gearbox when using "no lift shift" mode on the Camaro. Im guessing this wouldnt have any effect on that functions operation as this is just hardware.

As long as you are between 5000 and 6400 RPMs and at full throttle you can do a "no lift shift". Just keep the gas pedal floored, engaged the clutch, shift gears, and release the clutch. The computers in the car wont let the the engine over rev and start bouncing of the limiter when the clutch is engaged under those circumstances (gas pedal floored and RPMs between 5000 and 6400).

Anybody know if those bolt on sequential shifter kits will work with auto rev matching?

Agree. Loved the DSG in my modded GTI. The harder you accelerated, the quicker the shifts. Always drove it in manual mode. Instantaneous shifting. Literally a clutchless manual.
