🤣 There are a bunch of Ecoboost guys in the area, There is a meetup at Great Lakes Dragway Apr 8th set up on Facebook. Right now I have a tune from Torrie, GFB, and Steeda intake, hope to get an IC and possibly the upgraded XDI HPFP by that time.
May I add, my previous Fusion - aside from the hard shifting that had been fixed, I also encountered the "bang / slam" phenomena under the same condition.
FWIW, I just got my MKZ from a garage after a Transmission and PTU fluid exchanges yesterday.
I drove to work today and was trying to replicate the same phenomena.
Much as I tried - and if I am being very an*l about it - I think all I had was a faint (very faint) nudge, no "bang/slam" at all, more like feeling a just a regular gear change.
Now, it was only a 3-4 mile drive. I will try to observe the vehicle's behavior as days goes by and report back.
I get a bang shift if I get off the throttle in the midst of a low-speed gear change also. But that has happened in every car I've driven in the modern era equipped with an electronically controlled transmission.
Exactly the same for me..as well as 2-1 feeling like I'm being rear-ended and I believe it's 2-3 or 3-4 there's about a second or so delay between shifts where it revs but no power and then it kicks in.
Seems like there are two different issues mentioned here.
I do not have the 1-2 hard shift on my MKZ but I did have the same issue on my previous 2014 Fusion + harsh shift in reverse.
I do have "slam" and I can replicate it almost every time.
For me, it ONLY happens during light acceleration AND while I happen to release the gas pedal before a change in gear completes.
For mine, I think all they did is check the trans fluid level. They did take it for a test drive, but I also had them checking a rattle. They probably blew off the whole clunking from 1st to 2nd. I will have to take it back in just for that issue, I suppose.
