Is there usually info about a transmissions power loss? It’s usually assumed around 15%.It's good to know that the shifting speed is fast. I'm concern of the power lost as well. Interesting is there no info any where about this.
Modern 8spd auto transmissions are crazy. Word on the street is that Hyundai originally designed their 8spd in a similar way to the ZF8. If it is indeed like that, then you've got 5 clutches and 4 planetary gearsets. It all stacks together in an incredible way, with the clutches/brakes electronically controlled via the valve body with pressurized ATF.
On top of this, I don't know if Hyundai designed their own torque converter too.
DCT transmissions don't use a torque converter, and the input shaft is usually able to directly drive the two clutches.
I've rebuilt a Honda FWD manual 5spd, and installed an LSD in it. It was a cool project and after that I finally understood how most manual tranny's work. Automatics, on the other hand, are way over my head.
In my opinion, DCT's are easier to understand when looking at a cutaway view than modern 8spd autos. That said, I still don't understand exactly how 8spd auto tranny's work, and I probably don't really get DCT's either even though I'd like to think I do. Haha.
Dom didn't call it granny shifting for no reason.Maybe you should have taught her how to double clutch.
Oh I'm not giving in. For my daily driver in NYC I've accepted that having an automatic is the way to go, but one day when I have a garage and the means to have more than one car, it'll be something with three pedals and zero practicality; maybe a boxster or something. Even the best automatic doesn't scratch the itch like a stick does.Dom didn't call it granny shifting for no reason.
It's good to see other manual guys that are giving in to the better-shifting automatics that have come out in the past decade (praise be to ZF 8-speed). I've owned nothing but manual transmission cars since 2011, when I thought that automatics were nothing but fun-sapping bore-machines. Newer DCTs and even some torque converter transmissions have proven that wrong, recently. That, and there are no cars on sale today that interest me and have a manual transmission.
