I understand what you're saying, but I'm not sure the difference is that significant. The ZL1 is already somewhat traction limited in the lower gears with a 3:73 rear gear. I don't think it's likely we'll see GM go any more aggressive. Also, the final ratio in 6th gear is about as tall as I'd want on the interstate. Any taller and we'd need to shift for hills while interstate cruising.

To each his own. I don't have a problem with the 7-speed. I simply don't see it as providing a big benefit either. Even Tremec's documentation shows the 7-speed's purpose was for fuel economy ratings...not performance.

What's the source of this information?

I can see how an M7 configured for the Corvette wouldn't fit, but the Corvette is obviously different with its rear mount transmission. The center sections of the M6 and M7 appear identical to me, are they not?

I would think with the bell housing and the tail housing from an M6 it'd fit just fine... maybe I'm wrong though.

The length of the m7 case was the issue from what I remember.

The reason for the M7 is to maintain track ability and squeeze out a few more government mandated MPG. Doubt you would ever use 7th on the track, I doubt you use 6th that much.

Let’s hope that m7 and a8 is for an upcoming LT5. Quite surprised 2019 zr1 didn’t push their auto tran to A10.

It won't fit C7.

I asked the same question about the ZR1 and was told the A10 wouldn't fit the C7, which is why the ZL1 got it first. Probably has to do with the torque tube.

Much like the M7 being just to big for the Camaro I believe the same goes for the A10 in the vette. I believe it was just a hair to big to be used in the current Corvette platform

Its traction limited due to tire selection...easy fix. If it had a steeper gear you wouldn't need to shift for a hill, it's the opposite. It would pull easier under load.

Pretty sure I recall one of the Camaro disciples confirming the 7 speed won't fit in the 6th gen chassis back in late 2015.

Even though it's highly speculative, I don't see any issue with GM actually going through either the gearbox housing and/or camaro design, and making a modification for 2019 or 2020 to fit the M7. They did say it was close to fitting, but not quite.

I'm not saying that's what's going on here, but just because a car couldn't fit the M7 a few years ago, doesn't mean they haven't solved the issue by now.

Sure, leave this raggedy ass A8 in the car. That will help sales. They still have torque converter issues on the 18's now. The shift characteristics of the A10 are light years better than the A8. That's been said by several shops that do work on the SS as well as the ZL1.
