I just bought an '05 S 4x4 w/ 6MT. Every time I shift above 3k, the motor or gearbox 'growls'. Its not a metal on metal sound, and its not the sound of the motor spinning down. The sound starts the second I put the clutch to the floor.

At first I thought maybe I wasn't letting off the gas completely before I disengaged the clutch, but after a couple of very deliberate shifts, it was still doing it.

I've been short shifting it in the mean time, but has any one else experience this?

TIA,
M
