UPDATE: I called the Ford dealer, they said they 110% replace the torque converter whenever they replace a transmission (which was replaced 1.5 years ago). Matt from GH was talking about strategy codes and the valvebody with the new tranny as well, so I asked about that and the Ford dealer said they have to do that or else the new transmission just won’t work right. Now, the torque converter could have gone bad over the last 1.5 years, although I doubt it? Kinda just bummed. No idea what this could be. Matt sent me a softer shifting tune which helped minimally, but the problem still persists. I do have a warranty so I can bring it to Ford for free but in that case, I’d have to revert my car back to stock and then the problem may not be there anymore, in which they’d probably just tell me that everything is fine. Dealt with this issue with LMS for almost 2 years, decided to buy GH and it’s still here. I still doubt it’s the GH tune since all of you have like no issues, but damn, tranny mounts could be contributing but I doubt that’s the culprit of all this. Annoyed.
