I forgot to mention that i checked the flex discs and they seem fine with no cracks on them. Now the clunk is actually very unusual and harsh, I had 12 early-mid 80s MB diesels before and most shifted hard and some clunked but it was a different kind of clunk not the horrible about-to-fall-apart kind of clunk im getting on this one. Another interesting fact I forgot to mention is that it does not clunk if I start to drive and shifts into 2nd only and I come to a stop, but if it shifts 2nd then 3rd and then stop then it does clunk...pretty mysterious eh?
