Took the 510 on its longest journey yet- up to Limerock Park (1.5 hrs or so) got a to take a couple parade laps - pictures latter when they are up...
Any way ran into an issue on the way home...
The car drives fine as if there is no problem - no issues getting it in gear, no odd noises, other then the whine in 4th and 5th, but its done that since I bought it and
I always figured it was because there was nothing to insulate the sound (no carpet or anything inside the car)
I believe it is a 280zx 5spd
What it is doing is that when shifting or in neutral with the clutch in it will get a rattle or clank, almost as if there is a piece of metal in there that only gets picked up and bounced around sometimes. but it only happens when the clutch is disengaged i.e. pedal to the floor, seemed to be more prevalent in the 2nd to 3rd shifts but had it happen in the 1st to 2nd and 3rd to 4th.
Just changed the transmission fluid last week. I had the speedo gear pop out of the transmission housing- no damage to the gear, minimal driving while it emptied ( 1 shift, and maybe a mile) Replaced with Redline MT-90 transmission gear oil - yellow metal safe - felt like there were smoother shifts after changing.
When I drained the remaining transmission fluid it came out surprisingly clear with very few metal shavings on the magnet.
Any help or insights appreciated- been searching, still searching, but I have a pretty limited knowledge of transmission.
