Slowest speed a DCT is fully engaged

I own a 1.6T DCT. Can anyone tell me the slowest speed I can travel while having the transmission completly engaged (no slipping)? I know creeping is bad, but what about 2 or 3 miles per hour? Is the transmission riding the clutch at that speed?

Lately rush-hour traffic has been very bad with miles of start/stop driving. I try to leave space between me and the car in front, then take my foot off the brake and let the car get to its speed without pressing the accelerator. Digital speedometer says 2 to 4 mph. Is it fully in 1st gear at that low speed?

It all depends on load, speed, incline, etc.… You get the idea. It does engage quickly when already Slightly rolling. First gear is very low and designed to engage quickly. I would say if you leave enough room to drive slowly you should be OK.. Keep an eye on the tachometer too

What should I look for with the tachometer? If it can give me a better idea of what the transmission is doing (slipping vs engaged) it would ease my mind.

This is my first DCT and I love it, but I want to make sure I don't ruin it.

even if you leave it in 1, it's going to disengage and/or slip at a certain point. curious about this too but I just try to leave room and "force" it to engage fully when I can. luckily there isn't a ton of traffic around here, maybe 5-10 minutes in evening rush.

From what I can feel its about 5 mph to keep everything engaged. However when you stop then go again it will ride it a little longer. It seems if you hit like 10 mph then back off it full engages it and keeps it engaged.

I try to either be on the brakes ready to stop or not touching the brakes at all. I figure that even if its riding the clutch I don't need to make it harder on them dragging the brakes too.

I agree 5 mph. I also wait for 5 to 7 car lengths before starting so I am not starting to move 1 car length and if someone sneaks in front of me or gets pissed ....oh well... my clutch is more important. I almost always drive in manual mode in heavy traffic. I also stay in 1 st gear as long as I can and I will go as high as 4,000 rpm before going into 2nd. I have towed my boat with this method in heavy traffic and have NOT thrown a clutch over heat warning. So I am doing something right it looks with all that weight.
