I am sure the engine is fine revving at 5k as long as the oil cooler and radiator can keep up that much of a sustained load/heat(some modern gasers can't). I just don't want to hear it. I had to in my 4.6L and it was teeth chattering to hear it scream up and down the hills for 150 miles. Although if you are revving that high for such long periods of time on a regular basis then I would do the severe duty cycle in preventative maintenance.

I would have put it in manual and forced a downshift, and yes it needs 4:10's and a 10 speed.

Then again, 4:10's may have left it screaming at 5500 rpm on that climb depending upon the gear spread and whether it could pull the next one. I totally agree that 10 gears would be great, so much so that 4:10 wouldn't even be needed any more.
