Clunk noise on the 1/2 shift in an A999 trans.

I'm familiar with the clunk when letting off the gas at the wrong time. This is not that. It is when steadily accelerating from a stop. I will say that I have been driving it a little and it's getting better. I still need to pull the pan and look around. I'll look at the accumulator and spring now that I know about it. Is there anything else I should look for? Obviously I'll look for filings and friction material in the pan and valve body but I'm scared to do too much in the valvebody cause I have been having a recurring nightmare about springs and checkballs flying out of it and never being found again. :-)
