every time when i get to 60 mph from 4th gear going to fith gear it grind. but normally when i drive from 30-50mph into fith gear it dont grind.what could be the cause.

Hi toubeevue,

You mean the engaging of the 5th gear grinds when at higher speed only?

I would suggest checking the gear oil level and condition. When was the last time you replaced it? It could be a faulty 5th gear synchronizer ring gear and hub assy.
