Hey there,I’m new to the forums. This is my second 1984Z. I got another one after having one along time ago. Anyway, it’s only got 60,000 miles on it and when you shift in and out of gear putting a load on and taking a load off of the transmission and drive line, there’s a clunk both engaging and disengaging unless you do the clutch insanely slowly and perfectly - Which is not close to normal driving. I’ve narrowed down that the clunk sound is coming from somewhere underneath the shifter.we thought it was on the rear of the car. The car now has a new driveshaft, new clutch, new fly wheel, transmission oil changed, new subframe bushings, new differential mount/insulator all done professionally by a mechanic that’s very experienced. The mechanics aren’t sure what to look at next. I jacked The rear end up to get the wheels off the ground and put it in gear and put the clutch on and off to determine that the sound was coming from somewhere under the shifter (mid area) of the car rather than something at the back. Any ideas? Thank you
