okay brick nuts, hate to bug you guys again, but I was going through my ipd catalogs and reading up on their tips and articles. maybe it's a non-issue, but while looking up the price for their atf flush hose, I came across the sentence that says something like "easily connects to UPPER transmission line on the radiator." I read the faq on draining the tranny and it also mentions "UPPER" transmission line. my recent atf flush at a volvo indie shop, I think the tech removed the lower transmission line (the one that's closest to the belly pan). or is that the upper? in any case, does it matter which one to unscrew for flushing the tranny? I hope to do my own tranny flush--keep hearing it's a piece of cake, maybe a whole cake. thanks again!
