Doesn't the 85 have the torque converter drain plug? I have never gotten much more than ~2 qts from the pan only.

The transmission pan is similar to the valve cover gasket. (It must be a particular with rubber gaskets.) I had good results with an initial tightening and then another tightening after the transmission was warmed up. Unless you are really good, I found a torque wrench was pretty much mandantory to get everything evenly tightened. Overtightening seems to warp the pan and anything you do seems to make it worse. My pan was warped from the start and I ended with replacing it rather than deal with the frustration of constant leaks.
