When I took mine there was no restriction (WA state) but you are allowed a lot fewer mistakes on your road test with a an automatic vs. a manual. I want to say you get up to 25 boo boos with a manual, not sure how many with an auto but its substantial - maybe 10 less.
I think some are just lucky (so far) - we rented an 07 last year and it did it just like the rest. Dealers and FL know about it but do nothing and keep making the same switch.
The M2 I drove did that at time too - had it checked but they didn't find anything. Later on I got under there and wiggled the lever on the height control valve and sure enough - you could hear air leaking when the lever moved fore and aft. It never got worse or bad enough for the owner to...
When I bought the T300 we did oil samples on the engine, trans and RE, reports indicated the trans and diff were slightly dirty but nothing excessive so I went ahead and addressed other things first. As the weather got warmer (ok, hot for these parts) it got more clunky and more reluctant to...

Sounds a bit low, what is your rpm at that speed? Tire size?
I have an 03, 3126, 4.63RE, 10spd Eaton, with 11R22.5's. It is overgeared and only turns 1750 and 60 and still gets 9.25 with a combination city/highway
That's funny but I suppose not that surprising considering the intelligence of some DMV personel - there is an interview process before you get one, in theory they would have caught it then......................one would hope.
I'm curious, if you can swap gear positions - can you take a 10spd overdrive and replace 10th with a direct (non OD) drive gear? I'm about 200rpm low and the only other option is to re gear the rear end which in some ways would be not so good as it would put the truck in 9th going down the road...
