If that's the case, there's nothing to worry about at all. I've had it work that way during 2-3 upshifts when towing up a hill. It's a VERY "Hard" shift.

I checked it out and I'm not seeing any locking going on b/w 1st and 2nd. The only time I'm seeing it lock is after I drop into OD and I'm on the gas. Seems to be pretty random....in most cases, the shift feels fine. It's really a sweet spot where I'm at just the right speed and RPMs and it only happens when I'm VERY slowly accelerating.....e.g. bumper to bumper traffic where I'm having to creep forward 50 ft and then slow back down again...and there's not much room to really accelerate.
Is it normal to see the comm gear advance prior to dropping into the corresponding gear? If I'm accelerating moderately, the interface shows 4th gear at 32 mph.....I don't actually drop into OD until about 40mph, which is when the TC locking occurs.
