1999 F250 SD 5th gear grind
I have a 1999 Ford F250 Super Duty with a 5.4L engine and 5-speed manual transmission. It has 261,000 miles but im not sure if its the original transmission or engine. The transmission shifts ok 1-2 and 3-4 but when i shift to 5th gear at low speeds and low RPM it grinds. I can wind the truck up to 55-60mph+ and shift to 5th gear and it goes in real smooth. But if your just lugging around taking it easy it grinds going into 5th. It seems to be getting worse at times. Any suggestions on whats going on? Thank you for you help in advance!
