    That's one tall #10 gear then.

    It has a lot of range to cover.

    Look at the rpm/speed reading....GPS speed is accurate. If I do 67 I'm at 1700 rpm....and I'm bobtailing now with truck and trailers on my ###.

    With an OD top gear, 3.70s and 11r24.5 i am at 70 doing 1500rpm so that dont seem funky, but i dont shift into 7th until atleast in the 40s or higher so you sound like youre having clutch slippage to me. Cant think of much else. Gears mesh and thats that, a direct coupling. Only the clutch is a friction coupling that could allow a variance between input rpm and output rpm.
