My guess is that's RPM/paddle shift related. Probably a built in fail safe to keep you from breaking your transmission. Why are you using Paddles during high speed runs?
I love using them. But I would imagine it would be no different in a roll race scenario? Paddles give you the best advantage of putting your car in the power band before a hit. I guess I could try the same thing in automatic and see what happens. I haven’t tried that yet.

For a roll race scenario, you gonna stay in manual, but once you WOT you don't wanna use the paddles, but pushing the gear to "D" once you started and leaving the auto doing its thing (you don't even have to press the button, going from "M" to "D" is just about pushing the lever forward and it locks). You gonna have the best performance.

I still use manual in my "normal" (spirited driving), because otherwise once you relax it start to change to higher gear and you gonna lose the "momentum", but on track and in every circumstances when you're sure to maintain high RPM, driving in "D" would be preferred.

10/4 I’ll give it a shot described this way.

You probably don’t even need to go that far. @npole is correct that unless you’re in manual mode, the paddles are only in effect for a limited time but for what you’re trying to replicate, the Auto is probably going to be better.

I thought in “s” the paddles were the only thing that allow the car to upshift? It will downshift on its own coming to a stop but otherwise the driver has to upshift. That’s how these runs are being done in “s” with paddles

You may upshift and downshift with paddles either in drive mode or manual mode. In manual, you control upshifts and downshifts unless you are stopping and going too slow, and then the 10R80 will downshift for you, so that you don’t try to take off in too high a gear.

Good on you if you can time that 1st gear shift to hit in the top of the power band but not hit the rev limiter, first gear is gone ... FAST.

Which is exactly why I’m confused. In my mind I should be able to max out to 155mph with no issues upshifting yet the car seems to cut power in the middle of a pull. Really need to figure this out. I’ll take any ideas lol.

I already told you. There is likely an ECU override when using the Paddles that kicks in at certian speed/rpms combos. I think ive seen it in a video somewhere. Put it in drive and try it again. And try not to kill yourself looking for something wrong with your car. 👍🏻

No, the only cut will happen (as I know of) because of rotational max speed of the 10AT transmission, and this is going to happen only in 6th gear (since with other gear it will hit first the rpm limiter or the speed limiter) at around 6800rpm, and it will not go above it (so it's not like what you described).
If it's happening in other circumstances, then there might be an issue (with temperatures or whatever...).

That does make the most sense. Yeah it otherwise is perfect. Doesn’t consume any oil that I can tell and runs awesome.

I’m gonna do a run in drive and monitor what happens.

It has to be this. Did a pull in sports mode in drive just mashed the throttle and it absolutely pulled no issues no hiccups nothing. Now I’d really like to understand more about what you are trying to say. In my mind whether in drive or using paddles the car should just go as long as you are not hitting the rev limiter.

I will try to explain the setup as best I can after inspecting it on my PP. I will reference the photos below.

Photo 1: The transmission cooler is shown with green and red labels in front of the pan. This cooler is the part that is the same on the PP as the non-PP. On the PP the lines on the left and right labeled aux cooler run to the front of the car where the aux cooler is located. On non-PP cars the line on the right runs back into the cooler on the left side where it is labeled aux cooler.

The center two lines labeled radiator run to the radiator on both the PP and non-PP cars.

Photo 2: This shows where the two center lines running to the radiator are located right behind the radiator fan as well as the lines running to the auxiliary cooler.

Photo 3: The auxiliary transmission cooler sandwiched between the radiator (rear) and a/c condenser (front).

Photo 4: Driver’s side of the radiator where the cooling lines connect.

Hopefully that is helpful for someone. It was interesting to me if nothing else.

Thanks for the photos! It really helped me, I recently installed the OEM PP transmission cooling system and made a post about it but I haven't had much driving or time to test and compare trans temps. What temps do you normally see during spirited driving or hard pulls?

Track driving on road courses (HPDE) it is usually around 218-221. I did have it get to 230 on a couple of occasions back when I was allowing it to shift on its own in auto mode a few times when the weather was cooler. I never got any code or warning, but the transmission started acting up at those temps. Kind of odd that it got too hot on cooler days, but never gave me trouble on a blistering July day at Road Atlanta. All I can think is it had something to do with the fan not kicking on because the coolant temp was fine, but that's just a guess.

I have since gone to exclusively using the paddles on track and haven't had any issues with temps over about 223. I do change the fluid about every 1,000-1,500 track miles and have an aftermarket PPE pan.

I don't imagine there would be any temperature problems with the PP cooler doing "spirited driving" or hard pulls. HPDE track driving is like doing hard pulls one after another for 30 or more minutes at a time.

BTW, I read your posts about the upgrade, and I'm impressed you saw the whole project through. I don't know that I would have had the fortitude to complete that. LOL
