Drivetrain clunking 1st gear
So I was driving around this morning and while in stop in go, just coasting in first I heard a clunk and I thought I ran over something metal? Looked back and didn't see anything so continued driving. I noticed now when in just driving in first gear I hear a clunk, clunk,clunk, clunk, clunk, clunk, u get the point. When I push the clutch in, the sound goes away and it doesn't happen in any other gear, just first when driving.
If it walks like a duck, talks like a duck, then does that mean my transmission needs a rebuild?
I'm at work now but I plan to have the car towed home and then start from there. If I see nothing wrong visually, should I just start with draining the oil? Also what other things should I try before I have to start digging into it. Never done the clutch/pulled transmission from this vehicle so if it comes to that, I'm sure that'll be fun...

When was the last clutch installed? It may be something relating to the clutch assy & not w/the transmission gears / synchros.
I would start w/putting the EvO on the lift (or jack stands)& getting underneath to do a visual first (take extra precautions to ensure the EvO will not tip off the stands).
With the trans in neutral, rotate the left / right front wheels & listen for any unusual noise. If you detect issues w/the wheel rotation the next step may be to separate the trans from the engine (that process may expose the issue w/the clutch (hopefully thats all it is)
Just my ideas! Keep us posted

Seems like the plan. Never done it before so this will be interesting and im sure painful learning experience. At this point I wonder if sending in anything else with it is necessary. Car has 118k on it and its autocrossed a lot on. Wonder if rear diff or anything needs a refresh or some sort of new diff rebuild layout.

If the car is going to be down, get the rear diff gone through and a 12 plate upgrade done, billet side cover, etc, won't hurt if you have the money. Same with getting the tcase gone through and doing the 10mm bolt upgrade, etc..
