Grinding While in Fifth Gear
Hello, I'm new to this community and just bought a 79 RX7 with a five speed. I've noticed that there is a grinding noise coming from my transmission when in fifth gear. It's not too loud, but it's enough that it concerns me. I just wanted to know if there's anything I can do about it.

So "grinding" like when put IN to gear? Or steady whine/grind while IN gear? One could be weak syncros, the other, just old age
My SA has a notable whine in top 3 gears, but at 107K mi am putting this off to old age, plus general road noise covers it up. Mostly.
I have run sync oil in TX and diff for decades. Shifts flawlessly.
Whereas if the crunch comes going IN to gear, that is a diff matter, tho again one that 'might' be mitigated a bit with synth oil...
