What does sport mode do?

[Blackscreen67]

Why so negative on adaptive shifting, has been around for decades, and as you note even takes into clutch wear and will adapt shift times over the life of the transmission to maintain shift quality and as you note reduce clutch wear.

AT's need slip you can not just instantly fully engage a clutch or brake, in a lock up Torque Conveter for example to mitigate driveline vibration. Modern AT's are amazing in terms of efficiency and the down speeding allowed with Lock up TC's and modern dampers in them. Slip is a much overused term in AT's the "Slip" takes place in milliseconds

Your right it has been around for some time. Yet the power input of these vehicles have proven to be more than the trans learning software's can adapt to.

This isn't to mention the ultra low viscosity trans fluids the 10R80 runs. Heat equals even lower viscosity which means added stress.

Just take a glance at this diagram.... there are so many potential failure point it's a stereotype for what happens when you get engineers around a table and choose to over complicate a design.



In the big picture Ford and Chevy are trying to replicate the success the torqueflight and ZF 8spd transmissions that are widely used by different automakers(especially ZF). They have done such by choosing to offer a 10spd, because its a marketable item and helps skirt environmental standards.

Not to disparage the engineers, but Trans engineers with these modern AT's allow us to drive such vehicles without Gas Tax etc, Agree the 10 speed is pure marketing vs the 8 Speed, spread of the GM/Ford 10 speed is less than the ZF 8 speed and some of the steps between gears are very small/not needed in the Ford/GM solution

thanks for the cut away, I would say venture this, would rather have a complicated 10 speed than a 2nd powertrain (hybrid) back on topic in addition to sport mode got to use Sand Mode in some really deep sugar sand on a beach. Sand Mode, 4 Low, with rear axle manually locked and traction control off, the Expy was a beast

the sport mode in city driving greatly improves the throttle response and the fun to drive facto

Hi All
Running 5 star 93 octane performance/tow calibration
Reprograms for more power & matches trans to increased engine output
Increases line pressure & modifies shift points
Really improved trans shifting characteristics & works with engine much better
No detectable "SKIP" sifting anymore
Very firm shifts at wot as well
Very happy with the results
Suppose you could just reprogram trans by itself if so inclined
Really works like it should have from the factory now
