This is what I found in this thread; https://www.bimmerfest.com/forums/sh...d.php?t=620293

"The 4F85 code is a result of the bushing on the input shaft having excessive play. Typically, your "E coupling" friction plates will burn up as a result. The shaft itself does not need to be purchased, an aftermarket transmission shop can purchase an upgraded bushing kit from Sonnax, part number 95030-01k, and fix this problem. I recommend a filter, and the six frictions, as well. Hope this helps anyone still looking. "
