Hi DRV,
the D1 "winter" setting where it should start in 2nd gear seem to work so-so. In my previous box it did when first trying wintertime when I bought the car. Didn't use it since. Then I had a new box last January (due to wrong fluid fill by dealer), I've tried D1 once or twice in chilly temp, seems to work, but when warmer not. The dealer doesn't have the detailed knowledge to explain but the tech suggested the box also measure temperature i.e. too warm outside won't enable 2nd gear start. I basically never use D1 and starting in 2nd gear can only wear clutches if anything but I still find the function strange. Keep in mind this box is not a rebuild but brand new earlier this year so should be fully functional according to spec.
To keep down rev during warm up I have found D3 to be the best. Even if D2 shift earlier once it warmed up slightly, D3 in my case shift earlier the first few hundred meters out from the parking, i.e. from first - second - third gear.
Never done the reset.
I'll try the D1 later today, haven't done that for quite some time.
PS. Never experienced much of the clunking and issues when slowing down in D, the previous box was good and with the new it completely went away. Buttering smooth while lightning fast.
