Shifter in S vs shifter in D and toggle to S+ (EcoBoost 10 speed)

[Gizmobiker]

In D (Drive) my EcoBoost Mustang shifts normally through all 10 speeds as any car so equipped.

If I shift from D (Drive) to S (Sport) ……I believe the gears will stay in whatever gear you paddle shift too. If you accelerate to the red zone, the ignition will shut down for a period of time to not cause damage to your vehicle.

If my shifter is in D (Drive) and I toggle to S+ (Sport plus) even if I use the paddles, the transmission will shift without red lining. If I choose to not manually use the paddles, after a period of time, the transmission shifts automatically up and down through the range of gears.

Anytime I hold the + (Plus) paddle for a few seconds, the transmission goes back to totally automatic operation.

I've learned that if you put the shifter in 'S' the car will shift automatically (but a lot more aggressively) only until you shift with a paddle. Once you grab a paddle, it will not return to auto shifting until you move the shifter back to 'D.' I never red-line my engine so I can't comment about that. Hope this helps a little.

Are you describing the operation of a 10 speed Mustang transmission, or your 2018 Hybrid?

Try reading the manual. And you can long pull on the right paddle to restore a measure of auto shifting.

This is how it works. What is your question?

So this is an excerpt from the main 10R80 FAQ thread, which will help anyone who is new to the 10R80 understand it and it's functions.

Pay close attention to the last link above and read all (3) pages. It has every bit of info to learn about the Transmission Mode vs Drive Modes and the tech about paddle shifting relationships.

This is the main 10R80 thread with a TON of informative info and links starting on Post 1, Page 1.

Everything is broken out into sections and there's a lot of info, plus included PDF docs too.

Your post describes normal operation.

The shifter position is for the trans and overrides the toggle.

In D it starts in auto mode and goes to "temporary" manual mode upon hitting a paddle. After 4 seconds it reverts to auto. For example if you are driving on the highway and want to pass you can downshift a few gears with the paddle, pass, and the trans will revert to auto by itself, and use its usual mellow shift points.

S has more aggressive shift points but still starts out in auto. Goes to manual upon hitting a paddle and stays there, but you can hold down the plus paddle to get it back to auto.

I use D all the time for around town driving. I don't drive sporty until I go on track when I use S.

Lol. My 10R80.
