Was driving fine then out of nowhere on the freeway at 65mph it started slipping in gear and is slipping in all gears. Could it be a bad transmission or a shift sensor?

Has the check engine light come on? Is the trans fluid clean and full?

No check engine light and the transmission fluid is clean no burnt smell, air bubbles or improper level. So I'm stumped. Thank you

I would suspect either you have low pump pressure or the clutches are worn. Since the fluid is clean and not burnt, chances are the clutches are okay.
