Put synthetic fluid in your transmission and shift slower.
The only way you can get a smooth "speed" shift into 5th is if you're at ~5500rpms in 4th gear. This is because you need rpms to match torque peak going into the next gear. If you don't, get kind of a thud. Try speed shifting the 2-3 shift at 4000rpms and you'll get the thud I'm talking about. As for the grind, that doesn't surprise me because 5th is such a long and complicated shift.
