SM 465 chatter/rattle

[red450ih]

Back in the summer I had to pull my 465/NP208 from my 83 K20(6.2 Diesel) for a clutch job. I thought while I had it out I'd have the local trans shop go through it and freashen it up. I get it back in and there is a terrible rattle at idle with clutch out. Also makes this noise in Low and reverse. He says (trans shop) I have a gas engine clutch, so I get a Diesel clutch and get him to go back into the trans to be sure all is well. Back in she goes, same rattle/chatter as above. This noise is driving me nuts and the trans shop is pretty much telling me all manual Diesels do this and I should learn to live with it. That is wrong. I have ran it for about 8K miles and it's getting harder to get in and out of 1st gear (not low/granny). It didnt do this before. Hind sight is 20/20. I should have stuck the clutch in and left it at that. The trans was quiet and shifted very well before. Anyone have any ideas? I may tear into it myself if the shop wont fix it, but they may get a call from the BBB. Oh BTW, it's not the shifter. I can take it out and hide it, still rattles internially.

Thanks for any ideas,
Keith
