Welcome to 2CarPros.
If the RPM's sound high but aren't, the first thing I think of is an exhaust leak. Have you checked the exhaust for damage, rust, or anything leaking? Also, when you say it doesn't feel like fourth gear is working, if you are driving at 60 mph, how high are the RPM's?
Let me know.
Joe
