It's not that Bad.... Sometimes when I'm in 4th and chillin moving about 40 mph i'll stick it in fifth! The car works just fine. It sure as Hell doesn't STOP. Rofl .... beside the owner's manual say's a Billion Times "drive in the Highest Gear that lets the engine run and accelerate smoothly." That's exactly what it says. When I'm in 5th doing about 40 the car runs smoothly at that speed, Its really sticky trying to accelerate though, then you need to downshift.
Besides the owner's Manual's recommended shifting points have you shifting at like 2200 rpms ...
