I have no idea Jr. I narrowed it down b/c it started out at about 87ish, I pushed the clutch in and let the drivetrain slow down, and it felt like it was no where near as bad, so then I put it in 4th to make the drivetrain go faster then when it was in 5th and it go worse. My thought process is, if my tranny shifts perfect and gives me 0 issues, and doesnt do this at a slower speed, it cant be the tranny. Its not the rear end b/c I pushed the clutch in and it went away for the most part, so it has to be the drivetrain b/c when I spun the driveshaft faster, it got worse.
Odd thing is, I dont ever remember noticing this in a 1st/2nd gear blast when im spinning it at 5500 rpms...so why at 2500rpms? If Im gonna run road courses and stuff, then I gotta get this fixed...so any help would be appreciated
