Not sure if this is something new I found (I did do a search) In normal drive mode I was cruising a 60 mph and I was watching my 10 speed transmission light stack on the dash. I was just playing around with the paddle shifters and I hit the (left) - shifter a couple of times and I noticed my number 10 light go out and the truck downshifted, so I did it again and 9 went out, another downshift. This is all being done in drive mode not manual. So i starting playing around more and I guess after starting the engine you can remove all the gears you want in drive mode and it stays that way till you restart truck or add them back with the + shifter. Does this work for others?
