Driveline clunk/slop and harsh shifts
Alright, I'm out of ideas on this one, anyone have ideas where to look next?
Clunk in Rear: Changed out the rear diff last week and this improved 10 fold but on quick transitions off the throttle I'm still getting a light pop or clunk in the rear end. Old diff was very much toast, something rattling around inside at times and there was a substantial amount of freeplay. New one was very tight, no freeplay between the axles and driveshaft. Spun very smooth, couldn't find any issues. Axles were replaced as well. I've also had the front flex disc replaced, replaced the rear thrust arms and there appears to be no wear on the rear flex disc. What am I missing?
Harsh Shifts: I'll admit I haven't done much diagnosis here as I was hopefully this was a byproduct of the bad diff, but I'm not that lucky. The car and does shift very smooth about 50% of the time. This would lead me to believe the modulator has adequate pressure? Fluids clean and seems to be filled to the correct amount, I am going to go ahead and change the fluid next week just to see, but I'm hesitant thats the issue. When it shifts hard it is really rough on the driveline and want to get this fixed asap.
