Considering selling my special order GT

[young at heart]

Im heading to the dealership soon for something else so I’ll try bringing this up again. I’m going to first ask to take a tech for a drive to see if I or they can replicate it on a short drive. If no luck, I’m going to see if I can at least capture the situation visually with my go pro chin mount.
When I’ve had the dealer scan it before, there’s been nothing they could find. I’ve used the built-in “send feedback” feature the last few times it’s done that or the less violent version of that.

Is your car an A10 or an M6?

Dang, is that really what your car is doing?
I guess I thought we were talking run of the mill hesitation but there's no way I could give my car half pedal without launching hard right away

Like 93% of the time, same.

A10

A10

You might want to have a knowledgeable and trustworthy tech check the trans fluid level. It’s supposed to be done at PDI but often is not because following prescribed procedure is a real PITA and nobody can “beat the book” doing it. Low fluid could easily cause your symptoms.

Thanks for that suggestion. I’d bet money that wasn’t actually done at PDI.

Just be aware that "track mode" switches off all the nannies like electronic stability control.

I tend to use sport mode for that reason. It loosens up the nannies, gives higher rpm and instant throttle response, but electronic stability control is still there to help out if you get over your head.

On public roads, esc is a good safety net to have. Unlike track driving, public driving has many more variables

It also appears that in Track Mode, the throttle response is not as sharp as it is in Sport. Although I like the downshifts and rev matching in track mode. My custom setup is always in Sport.

My first day on the track, I ran Sport Mode. I was surprised at how well it performed left in D.

My first day tracking this car I also ran mostly Sport and was happy with the powertrain response. I did prefer leaving it in M instead of D. The customizable gauge set on the infotainment screen was very handy, and thankfully kept my selected gauges in the same spots between sessions.

It does not switch off "ALL" the nanies.

Sorry - I did not know. What does it leave on?


EDIT: Owner's manual says they are still on but much less likely to intervene.

More discussion here

See especially ZXMustang's graph of the four various pedal inputs in the 2024 file depending upon mode selected. Interesting stuff.

So AZ_Ryan's response got me doing a lot of experimenting. I did not have access to a track, but on lower speed turns, first applying the throttle in Sport mode just enough to slip the rear tires a little, and then repeating the same turn and speed in Track mode required slightly more pedal to get the rear tires to slip as compared to Sport mode. This is another way of saying that Track was gentler on the throttle for the same partial pedal position, which is of course what you want on a track.

Track mode appears to give a lot more control over the rear tires - you can still apply enough power to overpower them, but it is much easier to modulate that power and even pull it back while still applying power.

Sport is more aggressive and more difficult to control the rear tires.

I now cannot wait to try out Track at the track instead of Sport at the track.

Track is gentle, controllable, and precise.

Sport is snappy, less controllable, and less precise.

Both descriptions are about part throttle application at the edge of slipping.

The transmission programming (A10 here) in Track was very interesting in how aggressively it downshifted whenever I stabbed the brakes. It was always ready to go and seemed to have more rpm ready than Sport mode even though it required more pedal input to get the same power. I assume full throttle is the same in both, but I did not experiment much with a fully open throttle as I was on public roads. This makes me more interested in trying out Track mode on the track, too. RPM will probably be higher exiting the turn.

Hope you get it sorted. I haven't had that issue. Did occur to me I might have and in my early 60s so one never knows, LOL. That and the thought if I myself had this issue I would probably go back and get another nerve conduction study

I suggested a while back this might be a transmission issue. I 2nd checking the fluid.

You have seen the light my son.

Not sure if it's the same thing the op has experienced, but I test drove several GTs last year. To me, all of them seemed to have a sluggish pedal response. It felt to me that I would apply throttle, and nothing would happen, but then I would push harder, and all of a sudden I would notice that my speed would be approaching 45+mph.

I attributed it to a combination of the vehicle's weight and throttle programming, but it just didn't feel good to me. For comparison, I have had two prior v6 mustangs, and own a 350, and none of them felt similar. I ended up with a Supra, and do enjoy it, but am keeping an eye on what Ford does with future mustangs. Hopefully future models will improve and I can return to having a mustang to daily.

Did you try track…aww never mind!

OP, one more possibility in addition to fluid. (This is for after you try track mode!). Your A10 may need a s/w update. Ford seems a little schizophrenic as to how they want it to shift. My 2020 GT shifts very hard most of the time. Kinda reminds me of the result of putting a Royal Pontiac Bobcat kit in the TurboHydramatic of my ‘67 GTO. There’s an update for it but I like it. My ‘24 GT A10 was the opposite. IMO it shifted way too soft. I didn’t like it at all but apparently most buyers wanted it. My ‘22-‘23s were all over the place but I traded them rather than try to make them better. Anyway, point is that funky trans logic could easily mask itself in ways that could be interpreted as lag.

Well, in fairness, I would still like to know how far out of shape Track Mode will allow me to get as compared to Sport Mode, as I would hate to find out this information for the first time on a 90 mph downhill turn. Basically, I would just like to know what ECS does in each mode.

Too bad Ford did not include a dip stick for the transmission fluid, so you could check in in 15-20 seconds with no tools but a paper towel.

Sounds like you need a track day.
