So it looks like the 24270599 OS is for a 2014 application.
It doesn't display a vin on my end so that's all I know.

I know things changed through the years and not everything is fully mapped.

What all is different from your 2012?

It's seems like the tc lockups were crazy early and some of the shift timing and pressures were all different. That could just bee the difference between 2012 and 2014. I'll have to find a similar stock 2014 tune file and compare, or post the 2012 and let you look too. Also, what I don't know could fill the grand canyon so there's that too.

I had to turn off my tcc lock up in all gears to prevent the harsh shifting in regular driving

Edit: never mind I am thinking about an OEM system, not using this aftermarket system

Was about the unit not being compatible with the ABS System

Yeah there is a warning about that but as long as your not trying ti adjust the abs signal with the box vs just providing the correct signal to the truck, should be fine. I'm gonna try and see
