Well, I'm finally realizing after nuerous problems with Transmission shudder that Ford E4OD trannys are pieces of crap.Replaced torque converter (unfortunately aftermarket) and after 4000 miles on fresh motor there it is again.Thinking about swapping out with a C6 but dont know about any mods that have to be done to be able to do this.Has anyone ever switched out trans to a C6? I do a lot of towing anyhow so the OD doesnt really concern me.Anyinsight to my problem would be appreciated....Thanks
