New DCT transmission

[Beercules]

I noticed the tremec DCT trans (in the new gt500) a couple years ago, but thought it wouldn't handle the torque of our cars. Has tremec updated?
Why would you want an auto offer a DCT other than smoothness? You would have to worry about burning the fluid or replacing bands/ clutches.

Also, while I'm on the topic of transmission technologies... has anyone thought of a CVT trans? Beef it up and retune. It would keep the engine in the optimal range and have no wasted shift time.

The 13-14 6 speed was only rated for 600 lb. ft. The DCT in the GT500 is rated at 664 lb. ft. I haven't seen too many break a 6060, but the jury is out on the DCT.

CVT transmissions are the shittiest of all transmissions. DCT's are fine as long as you don't overheat the fluids. I've driven and had some of the best DCT's every created. They do shift fast, but I still prefer using my jerking off arm to row gears.

Ok, thanks for the information.

Overheat fluid in clutch assembly or manual transmission part?

That's a great question. I am assuming that the clutches will be of the wet variety since it is in a road car, so The fluid around the clutches must be kept at a nominal temperature. But like any transmission, the gears will see that fluid as well, unless it is self contained system that isn't shared between the gearbox and clutch hydraulic system.

Probably why there are so many different coolers on the new GT500.

So how do you launch a dct?

 

[HISSMAN]

Launch control. It keeps the clutch disengaged until a specified RPM is reached, then engages it. It usually doesn't dump it, so to speak. To do that a custom tune may in is usually needed.

So how do you launch a dct?

The 2020 GT500 has an electronic line lock and launch control.
