Testiment to the 904 Trans

Well, completed the fluid change, filter and installed new Chrysler pan gasket as suggested. I drain most of torque converter as well ( yes left some old in)...just hedging. Like stated here, given cold slipping, it likely is not long for this world but perhaps I'll get a season or two out of it before re-doing. It still seem to perform better, 1-2 shift is barely noticeable it's so smooth, 2-3 is a bit more noticeable. Reverse is perfect and when warm, no slipping at all in any gears.

It does have whirring sound ( had before fluid change too) that I can't quite isolate. Sounds like from trans??? Anyway, thanks for the help and we'll see how long she lasts?
