Hi guys,

I wanted to take some time for those looking at sequential transmissions and show you what goes inside of a purpose built unit, not just a conversion piece.

This is the same unit we have been running for seasons in GrandAm and very similar to the larger unit featured in our ALMS GT2 Corvette, and the very SAME unit you can buy for your own project.

With over 45 different gear ratios you can custom tailor this box to each track and your car for the ultimate in close ratio gear boxes

These are all built to order and come in almost 20 lbs lighter than the OEM gear box and feature pressurized, filtered oil to all bearings and gears. Straight cut gears with of course replaceable dog rings for engagement.

Assembled main case


Tail shaft removed showing reverse gear


Comparison of the reverse gear to the main gears
Notice how much wider the forward gears are


Shift forks, notice they are gun drilled and feature pressurized oiling passages


Look inside the main case. Notice the large roller bearings and also pressurized spray bar for oiling to the gears


Main gear cluster


Huge main roller bearings for main shaft and counter shaft


Main shafts and shift rail


Gun drilled main shafts, again with pressurized oiling passages


Main shaft support bearings in place


Built in oil pump


Fine micro filter assembly


Oil pick up tube









As you can see it is more than just a face plated, or dog ring gear box T56 that goes into each one of these gear boxes.

While they may not be for everyone, I hope this shows you a bit more info on what goes inside of one of these awesome units! Feel free to hit me with any questions you have!

I need to stop clicking on these threads...it's just too painful.

I've searched for a bit but really couldn't find a good answer. For my own education, what makes these so much more expensive compared to a regular T56 or TR6060 gear box?

I learned on the Saenz. If I was still racing we would have some of these.

OUTSTANDING job guys.

Hey Anthony - is that one going in Mike's car?

Not yet.

The biggest factor in the cost is number of units made. Think about if you had a huge production line cranking out hundreds of transmissions a day that fit Camaro's, Corvette's, Viper's, Aston Martins.....or one specialized unit that you might make 20-40 each year, and even less that fit in the Corvette.

Next, look at the machine work that goes into each part. Your stock cast alum shift forks are not billet steel, polished with oiling ports in them. The main shafts are not quite that big, nor of that material...and again not drilled for oiling passages. While some of the C6 6spds do have an oil pump on them, they just circulate the oil...nothing is pressure fed to the gears and linkages.

Nevertheless, Lou, I think the price is quite high.
I have long thought ... Währe the price not quite soo high, I would have bought.

As an amateur rider but I opted for an optimized gear ZR1 with Diff 4.1. works perfectly

the machine work is wonderful

What is the price? I don't see it anywhere.

Last I saw it was about $25k-$30k for a sequential to fit a Corvette...

If LG has gotten it lower than that...more power to him. But it is pricey!

Compare that to a true sequential S5D transaxle from Mendeola for <1/2 that and you can see the sticking point...get them in the mid-teens and I think more would buy them.

I know Lou doesn't control the manufacturer pricing...it's just a shame that only a few can afford to dish out that kind of cash for a transmission.

$28,500 is current pricing....

The CG 46 emco is a "true" sequential transmission. I have one in our race car and have installed two others of which both are paddle shifted. We have not had any issues with these units. The paddle shifted units shift between 40 and 45 mil. sec. To give you an idea how fast that is a F1 car shifts 30 to 40 mil. sec. It is flat shifting up and blip throttle down. No toe/heel required only brake and gas. The CG46 is a direct bolt in for the tremac in a c6 z06. You get what you pay for and it is made here in the U.S. of A.

Thanks for taking the time to answer. I figured there was custom machining and higher end materials used. Didn't at all think about numbers produced but that makes perfect sense as to the price.

A genuine work of art!

I would also add that each piece is serialized, and has a part number on it. You know when each part was made, and how old it was.

It makes keeping track of mileages much easier.

If you guys think this is expensive, you should price out an Xtrac, or emco transaxle with axles.

A set of Emco axles for these cars is 14k$. Its a drop in the bucket when you spend a LOT of money to get to a race, only to have a stock axle fail.

Its all relative, and everyones budget is different!

Cool video from a customer's ZR1 that just installed the Emco in their car.

Flat shift was not hooked up for this video, so you can see even without the added electronics just how quickly you can shift this vs a standard 6 spd.
