I'll bet the seal may have been bad out of the box? It seems it is hard to get good quality in parts today. You cleaned out the seal bore, right? I'm just trying to be your check list.
Yea, on the FX3. I don't know why all the DTC's. It drove me nuts. Just bear with it because I know you know it went back together right!
