I'm bumping this thread up with some results. I brought my 11,000-mile Mach 1 into the dealership for several warranty items, including the reverse clicking noise. I didn't realize this SSM existed until the mechanic put it in his service notes. If you are still under warranty, bring your car...
PSA - Ford and GM co-developed this transmission. Expand your research to include Camaro A10 threads; you'll find more helpful information.
Here is how one dude fixed the 4-5 flair in the tune.
Big thanks to all of those who contributed to this thread. I brought my 2021 Mach 1 to the dealer, and the driveline mechanic confirmed that what I was feeling/hearing was not correct. Loud, mechanically clunky downshifts, some of which would give feedback through the brake pedal. The dealership...
Would you post some photos of your setup, especially around the rear? I got a pair of 18x10 Welds for drag radials to pair with my 20x9/20x10.5 Weld set-up. I'm running Falken FK510s 255/35 and 295/35. , and I recommend these tires.
I have similar symptoms with my 11,000 miles 2021 Mach 1 A10, except the scope of my symptoms has grown to nearly all downshifts. The symptoms became known around gear 4 downshifts but have since grown to the upper gears as well. My local dealership has requested a full transmission replacement...
Try another dealer. My friends A10 Mach 1 needed full replacement at 12,000 miles or so. The dealer cost for the transmission was under $3k, plus fluid and install time.
FYI ~ Steeda released drag springs for Magneride S550's a couple of months ago.

Thank you for the tips. I didn't know that the torque converter would go up that high. My Mach 1 is an A10.
Yes to the burn out box. I love burn outs. No wheel hop that I could detect but I'll admit that I wouldn't know what to feel for, I'm new to drag racing.
I pulled my LexisNexis report and nothing showed up, meaning that I never activated whatever Ford service tracks and sells the data.
Verisk updated their website to state that they do not collect data from Ford...
I raced my 2021 Mach 1 A10 on Falken FK510s tires during the Muscle Cars at the Strip event in Las Vegas and had quite the experience. I ran in the Modern Muscle bracket racing class and competed against 44 others. Unfortunately we don't have a 1/4 track in Utah which resulted in me having to...
I posted today on the Mach 1 Facebook group asking for photos with the Steeda drag springs. I didn't know until now that they just came out. Thanks for giving us more choices Steeda.
I was recently down this road myself and found that the 35 or 50mm rear offsets on some of the most common offerings are too aggressive for my taste and are poking a bit. Additional camber can be added to make them tuck but then it gives a stanced look, which I am not fond of. My suggestion is...
