Wonder how difficult a gt500 dct trans swap would be
To be completely honest, that isn't going to improve overall performance. You're losing gears and not shifting any faster at WOT. It may be cooler to say you have a DCT, or run cooler on long track events but other than that it's alot of work and money for not much benefits.

It's a very good valve body. Despite what you read on some forums.
I only heard heartache from end users on this valve body. Do you have it and have got it working well? Or know someone that has? I'd just like understand the basis for your confidence. I see there is a more traditional simple shift kit out there too. I forget who makes that one. Thank you for any further info. I'm interested in making the most of what this trans can be with my 510 rwhp NA build.

100% agree! A DCT swap would not net you many performance gains. In fact, if you run a supercharged GT with slightly less hp than a GT500 the 10R80 beats it every time. The 10R80 is good because of how close the ratios are. In reality we are talking milliseconds that separate how fast the transmissions shift at. In terms of straight line speed I'd pick the 10R80 vs the 7 speed dot simply because of the ratios.

Congrats, you cracked the code on why your auto only cost $1600 more over base, compared to cars with PDKs that start at double the Mustang base price.

I knew I would hate the 10 speed any time I had to downshift at speed. No way you'd catch me buying an automatic Mustang.
Can no one here account for the latency? It's pretty predictable, just click downshift half a second before you want to its pretty simple really. Seems like just incapable drivers IMO, its a minor inconvenience that is easily bypassed.

As opposed to the latency that it takes for a manual shift to happen between the gear change and releasing of the clutch.

sure, but is it unreasonable that when commanded the hardware follows thru in a timely fashion? It's capable of it, obviously. Just needs software not written by Ford Mustang team.

The latency is more than likely a "safety" feature designed to prevent unnecessary wear and tear on the trans. So yes technically if that wasn't built into the shift procedure then it could shift as fast or faster than a DCT.

Sure but then are you ok downshifting 3 times and it goes through each gear (which would take longer and be more frustrating) or would you rather downshift 3 times and it goes immediately to that gear? The latency is for a number of reasons, single clutch, wait period for user input (how many gears do you want to shift down), the rev match, and then finally adjusting line pressure through the shift. It’s there for a reason but the biggest delay is probably waiting to see how many shifts the user has commanded.

The 10R80 ratio steps are about as close as you're going to get with any conventional automatic transmission and Ford does a better job than GM in designing clutch pack drag and end clearances by using waved separating springs on the A and B brake clutches (for piston return and low drag) and selective snap rings/pressure plates(backing plates) for precision end clearances. There's a lot going on to manage the multiple clutches in any of the 10R family transmissions and so much complexity that could lead to a failure event where a DCT only has to manage manipulating alternating input clutches. 10R80 is ideal 1/4 mile at a time but I'd trust the durability and reliability of a properly engineered DCT over a conventional automatic for extended road/track use. What's interesting is Ford wouldn't spend the money to upgrade the 10R80 for the GT500 (like GM did on their 10L90 version in the ZL1 Camaro) yet Ford is sticking the 10R80 in the Rapture R instead of the Tremec DCT.

I'm not doubting your accuracy, but the verbiage reminded me of this:




Good Stuff....!!!!!!!!!

The people that say that you might not get much performance increase from swapping the 10r80 with a DCT from the GT500 which may or may not be true but I guarantee the DCT will be way more fun to drive with paddles and the instant downshifts.

I have a '22 SS 1LE A10 and I drove my buddy's '22 GT A10, the GM software is so much better and faster.
The damn irony here is that Ford led the development of the 10 Spd...Chevy led development of a 9 Spd which Ford opted to not even use. Yet GM software is better, and it even has the feature where you can hold the left paddle to get the lowest available gear which Ford for some reason omitted. $%^#
