The previous owner said that he had the trans flushed last summer, and he put ~5k miles on it. So I don't think another 200 or so till this weekend is really going to hurt it. I did pick up a case of ATF+3, and I'll run it through it and do a "psuedo" flush this weekend and replace the filter.

I'm also getting the ATSG manual from ebay to see if there is anything good in there, maybe I'll finally rebuild one of these trans.

A couple of guys over on dsmtalk say that theirs does this on a regular basis, although I'm not sure if they have a mitsu or a chrysler trans.

I'll try to keep you guys posted.
