well thats what i was going to do but my friends gramps thinks hes a genious so i took the stuff back ,,
he said if it only grinds one gear; that gear needs to be replaced

He's right for most older vehicles. Newer cars aren't exactly the same so it is possible for one gear to go bad... I could be wrong on this too but I seem to recall having this discussion with someone else (outside of the forum) a while back....

A good synthetic MTF like Royal Purple or Redline may be sufficient to get a few more miles out of the worn synchro. The only "true" fix is to R&R the transaxle and rebuild it. If it was my car, I'd just double-clutch all my 2-3 shifts and 4-3 shifts. If you can't live with that, look for a relatively low mileage used unit from a salvage yard (make sure it has a guarantee of some kind, usually 15 or 30 days.) A competent trans shop can rebuild it for a couple hundred bucks if you only replace the really bad parts.

Yes, 10w-30 engine oil was called for originally. But with a synchro that may have problems, try Penzoil or GM Synchromesh fluid. Or even genuine Honda manual tranny oil. Neither of those fluids existed when your car was built.
