Reading that the DCT TCM is finally fully cracked

Here we go... let's take the 10R80 and make it seem it's better than the TR-9070

I don't think it's better. But it may be quicker. Still not convinced but the tide is going that way. Too bad it cannot be back to back tested.

Is that what’s happening?

My brother has a gt500 and is super excited for tuning… as to where the gains are

shift rpm, he says a few gears seem to shift 6800 inconsistently…
If it can be tuned for 7500-7800 rpm shift these cars will pick up a shit ton of ET/MPH

his 500 makes around 900 wheel but runs 9.9/145… they don’t get out of the hole like a fluid converter car can.

This was my thought. A well set up stall converter automatic and really launch and get out of the hole in a hurry. Might be able to mitigate any MPH gains youd pick up from the a DCT? Just spitballing here.

If I was wanting a real street type drag car I'd go powerglide or TH400 with an add on OD unit.

Or run a built 4l80.

.... insert feverish daydream of an Aluminator 5.2 XS coupled to a DCT....

"The GT500 features the 7-speed TREMEC TR-9070 DCT. This transmission is capable of lightning-quick shifts in as little as 80 milliseconds." - Team TREMEC April 28, 2020 https://tremec-blog.com/the-differences-between-a-dct-and-a-traditional-automatic-transmission/

Thats about 20% faster than Porsche PDK. -https://dealer.porsche.com/ca/rivesud/en-CA/News-and-Events/Transmission-PDK#:~:text=The%20result%20is%20ultra%20fast,this%20same%20generation%20of%20911.

"Based on Chevy's own testing, the 2017 Camaro ZL1's automatic( equal to the 10R80) shifts from 1st to 2nd gear 36 percent quicker than the Porsche PDK. The automaker claims the 2-3 upshift is 27 percent quicker, while the shift from 3rd to 4th is 26 percent quicker."- Mototrend Camaro ZL1 is first to get GM's new 10-speed automatic May 12, 2016
I think I saw reference to this in http://magazine.sae.org/auto 2016 as well.

Thats a tinnie tiny little bit faster than the TR-9070 DCT. Better... subjective.

I personally would avoid the headache that is V-Performance, for nearly no improvement or more likely worst in a DCT swapped car. I would just buy a GT500 or corvette if you want a fast car with a DCT.

I would like a DTC swap into my GT due to me liking to road race.

If I had a project car and I wanted a DCT in it, I’d do a BMW DCT swap. That swap has gotten to be pretty well sorted and there are several stand alone transmission controllers out there along with some stand alone PCMs that can control them natively.

If I wanted a fast, highly integrated, modern car with a DCT…I’d do like @markmurfie said and just buy a car with one.

GT500, 100K plus

GT with DCT swap 10K

I said I’d buy a car with one, not buy a GT500 with one.

If a DCT is that important, you bought the wrong car.

If I were to smoke my current trans it would be nice to have an upgrade option.
