2007 Chrysler 300c Trans Shift Scheduling Question

[Wesleyscott]

Had a question regarding the logic in the shift scheduling on my 2007 Hemi 300.
In the Shift Scheduling tab of the Trans, there is three profiles; Normal, Performance and Winter.
I am just looking to see if anyone has some insight into the profiles and what triggers them.
I see it states "based on Dynamic Driving Factor" and understand this will be a logic since there is no selectable drive modes on this vehicle as the newer ones.
My assumption is the Winter is used during a temperature factor, does anyone have further into what affects the Normal/Performance tables?
Trying to find out what factors play into these tables.
Thanks in advance for any info.

Hi,
The best is to post your tune, maybe some tables are not the same on all cars.
The driving performance factor is what it says.
Acceleration, braking and pedal way/time.

I have attached the stock and the current tune I've played with a little.

The NAG1 transmission uses adaptive logic and drive recognition software to determine when to engage more aggressive shift behavior. It could be triggered:
- Performance Shift Mode kicks in when the TCM detects:
- Heavy throttle input (e.g., rapid acceleration or WOT)
- High-speed deceleration followed by throttle tip-in
- Manual gear selection via AutoStick
- Continuous aggressive driving (e.g., aggressive cornering, braking, and throttle)

If you need support tuning, send me an email.

Really appreciate all the input so far! Has helped to confirm what I was suspecting. Having been a Benz tech/foreman for >20 years (until career change 3 years ago) I do understand the adaptations and purpose. New to HP Tuners and enjoying what I can play with.
I?m sure more posts/questions will come.
