Drove in Manual mode the other day, I could shift between 1-5. Can you not shift into 6th in manual mode?

Should be able to do it just fine... the computer, TCM still runs it so you can't do
anything too stupid..
Make sure your Tow/Haul mode is OFF...
should be able to shift into 6 at about 50 mph
