10R80 vs MT82

[howlins550]

Anyone driven both transmissions on the 18+ cars?

In a personal debate on which to go with, PP1 with the a10 or the PP2. Car will be a DD and see track use. The suspension setup on the PP2 along with wheel/tire combo is better for track use, however i feel those can be addressed on the pp1 in aftermarket. My biggest decision is which transmission to go with.

I have been driving a '18 EB PP car with the 6sp since Feb. It's my understanding that both the EB and the GT use essentially the same gearbox (different ratios). It is my daily driver in roughly two hours of Chicago traffic each day. It is very easy to drive, shifts smooth, easy clutch operation, etc. Not fatiguing at all. I plan to use this as an occasional DE car as well, which is why I got the manual. I could be wrong, but I'm skeptical that the GM/Ford automatic is going to behave properly on a road course. Very few auto makers seem to get this right, other than Porsche and a few other much more expensive vehicles.

I was the same way but I drove my buddies ZL1 and the a10 mustang, getting on them both with paddles and just in drive. Both are very impressive, downshifts were quick and responsive, the upshift obviously way faster than manual. However, that was public road and backroading over a short drive time. I don't have any drive time on track but judging how they both performed I'd think they would be awesome.

Still waiting to see someone performance test the PP2

Does the auto come with a trans cooler?

I'm not sure, I feel like I read somewhere that it did but I could be wrong

FWIW my biggest disappointment with the S550 is the MT-82. I find it noisy and rather clunky.
The 10 spd has been lauded by the press in other applications.

That said, I won't buy a car without 3 pedals.

I think I made that about as clear as mud.

Even with the 18+ improvements?

If you really intend to do open track then the automatic will cost more in fluid changes since Ford recommends fluid changes after every event with both.

The automatic has a cooler but I don't have any idea how well it will hold up to serious track use.

The "trick" I think with the automatic on a road course is to treat it just like a manual in that you will only use 3 or 4 of the gears of the automatic and certainly not all 10. Similar to a manual where you would typically just use 3 gears. Use manual shifting with the paddles with the 10spd versus manual shifting with a clutch and shifter with a manual. Don't use automatic shifting on track. Downshift one or more gears in braking zones and upshift as appropriate on the next straight.

The real decider is whether you are OK with the manual in normal driving. That is up to you. Happy test driving. :-)

That depends on the track and your gearing. With 3.73s all of the 3 tracks I run on I use 5 gears, though on 1 track it's only 1 brief place where I need 5th.

You use 1st gear on a road course? How slow are the corners?

Do you mean you use first on track? If so that is tighter than all autocrosses except full steering lock pivot cone 180's.

Anyway even with more ratios needed for the track manual shifting with the paddles is probably the best way.

Only times at a road course I can think of where you'd use 1st with 3.73's would be to get yourself rolling down pit lane on the out lap, to get moving again if the session gets red-flagged, or if you put 4 off and end up at or almost at a full stop. I suspect that even 2nd doesn't get a whole lot of use unless your tracks were designed by somebody who was thinking "Miata".

But that's still part of the deal, right? And as for 2nd, I guarantee you that none of these courses were designed for Miatas, but two of them do feature the "slowest corner before the longest straight" trick, and you do want a good launch out of that corner for sure and you know why.

What's wrong with Miatas, Norm? Fun car and a blast to drive.

Not as far as using it for maximum performance is concerned. That's for the dragstrip and stoplight crowd.

You must have some very tight corners. At my home track I'm only seeing 2nd for about 7 mph/750 rpm on one of the courses and you probably wouldn't be able to go WOT for most of that anyway. Maybe 10 mph/1000 rpm/same deal with WOT if you're pulling max-lateral on the other one. And that's with 3.55's.

With a DSG and active rev-matching, it'd start getting do-able and something you'd probably have to do at time trialing. The gains don't seem to be worth it at HPDE, and would probably come with a loss of consistency with a regular Mustang's 3-pedal setup.

Nothing. But tight, highly technical sections that are easy to drive in them aren't as much fun in something larger/heavier/more deliberate.

I was 110% set on a manual 2016. Than I test drove the 6R80 with paddles and was sold on it.
No worries about clutch, missing shifts, etc... And knowing I could leave it on "D" when I felt like on the daily drives. Plus, I can just punch it at times at it will find the right gear on the street.

I have HPDE my car many times and have zero concerns with how it performs. My transmission temps DO NOT change during a track event, they always stay the same.
I plan on adding a Procharger, I know the 6R80 is strong to handle it

Drive them, see what you like best, you will be driving it on the street 99% of the time.
