Okay so here's an update.. I finallybgoy around to put my car in the air. The noise I'm getting is because my tranny is sitting on the cross member. Not litterly but its rubbingagainst it it. My driver side engine mount is blown so I'm gonna put a new one and see if that fixes it. Any other ideas?

How your 5th gear feels?, if it has to much play, your fifth gear nut might back out and start rubbing the housing.

Has anyone figured this out yet? I just swapped transmissions and now my car is making the same exact noise (I can definitely hear it in the video) I've never had this problem previously
The car has an act2600 clutch in it, though before my last trans burnt up this noise wasn't never there

did you look at the face of the clutch disk? it will make a weird grinding noise if its wore down to the studs.

Well I should have been a little more specific. The trans is from a 1990 and the t case I put on was from a 1991. I was unaware until earlier today that they have a different tooth count which would explain why it was such a pain to put on. I swapped out the t case with one from a 1990 (luckily there was no damage to either trans or tcase), put fresh fluids in and it runs like a wet dream again. I watched the video and mine sounded exactly like graffiti. I wonder if he solved his issue and if he had a similar problem.

I'm surprised you even got it on.
