Default C7 M7 Trans mod questions

I have a few questions. I've been waiting over 3 years for 3.90 or 4.10 gears to no avail.

1. How much work is involved swapping gear ratios inside a C7 manual Trans?
2. How much is involve swapping from a C7 to a C6 rear?
3. Are there any other options, besides a auto trans?

I don't believe this will happen either. I also think the cost of tearing into the transmission isn't worth it for myself. It's unfortunate as the rear gear swap has always been a great option.

It should be comparable to a rebuild cost.

Are shorter gears available for the M7 transmission?

On a related note, I saw this weekend that Motive Gear is showing a 3.90 and a 4.10 gearset on their website. I'm thinking they don't really exist, but I sent them an email about them anyway.

You are correct. I wish they would just pull the damn page already..

Depends on which model C7 you have as there are three different M7 transmissions available, each with it's own gear ratios.

Gears for the C6z are produced, and have been installed in cars.

Don’t know why but Motive Gear decided not to produce those gears.I have talked to other companies it don’t look like it will ever happen.I’m thinking A good percentage of Corvette owners don’t want this.

Probably going to be a while for c7 gears. Hell C6z gears came out about 2 months ago. From 2006!
