Hi all, new to the forum so hopefully I am posting in the correct location but hoping someone can help with a transmission issue. I am nearing the end of a complete teardown and rebuild of my 5/71 240Z with the Monkey motion F4W71A trans. Finally got the car mostly back together and running, but I am getting an awful clunking sound from what sounds like the transmission that only happens in 3rd gear. 1st, 2nd and 4th all seem relatively quiet, I have maybe noticed a slight noise in reverse. Mayb
