Hi my s80 box drives well when I am cruising but crashes from third to fourth once I am over 100kms what could cause this.? Thanks

If you had searched you could of easily found an answer or a place to start!

Change your transmission oil, use Honda mtf3

If it is the case that it crunches at high rpm's it could be 4th gear syncros. Try changing gear by allowing the revs to drop more and see if it still crunches. If it doesnt then it is the syncros that are worn and need replacing. If it still crunches then as said above use mtf.
