Any input or similar experiences shared is appreciated.....when in Sport mode and down shifting with the paddles from 4th to 3rd it clunks...not noise but u can feel it...I have varied the rpms and it is always there....all other up or downs are smooth.....perplexed....vehicle has 4200 miles....thanks
 
Sounds like a dealer visit is in order.  Hopefully, there is a calibration update available to address the "clunk", I think a tune would likely fix it, but can't be 100% on that.

Have you checked http://owner.ford.com for any outstanding recalls that might apply to your SHO?
 
X2 AGREE with SHOdded,think a dealer visit is in order,think there is a new TSB related to a converter leak,definetly follow up on it to make sure there are no leaks,here is the TSB which was released on 8/15.  Z        POWER TRAIN:AUTOMATIC TRANSMISSION
TSB #SB45277
NHTSA ID #10058616

Thanks Z....no recalls...ran a health report via sync and I am already registered on the owner site.  Where is the best place to access the TSBs?  I used to work for Ford and had access to what the Dealerships had so it was very easy to keep up with issues.  I would like to be able to read the complete TSB if it is accessible out there somewhere.  Thx.
 
Thank you for the info SHOdded.  I surfed the Web briefly last night and didn't find much except for half or quarter TSBs
 
Yeah, the screws are being put to "free content".  So if you find a TSB, don't assume it's going to be available at that site forever & ever.  Keep a local copy for your own reference.  I made the mistake with fordservicecontent, but a firm kickinthepants from them learned me good.
 
Good to know....sure do miss my un limited access....Ford service guys hated it when I went in there with full TSBs

Yeah, I bet they did!  One-way conversations are very popular in service centers, unfortunately.
 
I have a 2015 SHO non PP as well and I also see a rough downshift from 4th to 3rd when using paddles. I have heard that a tranny reflash would cure the issue. Did you ever get your issue resolved?
 
Havent visited this Forum in a while so sorry for a way delayed response.  The Stealership did reflash the tranny and corrected the issue for about three months but it did resurface.  So gonna have them reflash at the next oil change.  It is not as pronounced as it was but still noticeable.  Its a leased vehicle so not something I am going to worry about as much compared to long term ownership and future tranny health concerns.  Believe me - from personal experience - if u own a Ford beyond its bumper to bumper the transmission should be ur biggest worry!
