Aright I'm gonna try my best to explain what's going on.
First Ill start with some background. '97 LT1 6-speed. Purchased the car with 64k on the clock. I'm the second owner, so I couldn't tell you if the clutch had be replaced or not, so mystery clutch/mystery miles on it. Never actually roasted clutch, although I did love tap a gear twice. Think that covers it.
So brought the car to college for the last month, a 6.5hr/410 mile trip. This would be the longest trip Ive ever taken it on. It ran great, cruised 70ish out here, did hit some traffic, did not ride the clutch very much. Up until then everything was fine, shifted smooth, no vibrations or other noises. I get off 79 to do a bit of back road driving and I noticed that when I went to put it in 5th (around 40mph so 15-1600 rpm), clutch pedal to the floor, I could feel what I think was grinding? but not nearly as loud like when you miss a shift. First I figured it was a fluke.
Well went back to neutral, then put it back into gear, and same thing happened in 5th, although it didn't happen every time. Also, nothing out the ordinary when I shift back to neutral (no grinding, doesn't jump out of gear).
First thought was a bad syncros in 5th, but I did note that it did it to me when I down-shifted into 2nd (around 20mph, rpm match). I made it to school let it cool down for a few hours thinking maybe it was running hot (70mph 6hrs you know). Was making a left, car was in 2nd, turned saw some kids so I nearly had to stop, low enough for 1st but as I put it in first I also got that grinding feel/noise
Basically to sum it up, car made a grinding noise/feel (pedal and shifter) after a long road trip. Does not happen consistently, every once and a while. Also note that it doesn't happen in every gear, nor is it consistent (doesn't happen more or less by consecutively going through gears or picking at random)
Open to questions so ask away!
I'm not gona use it much because I don't want to worsen whatever it is
