I wonder if it fails to downshift because at that altitude the engine doesn’t generate enough torque for the transmission to sense a downshift point

I wonder if sensors saw high temperatures after miles of full throttle and dialed back the power to save the engine or transmission.

In this video and the 2017 gasser video they mention all temps were in spec.

I am going to look at the Caprices tune tonight. It is pretty similar to the truck believe it or not.
I know the Caprice looks at speed/rpms/time/MAF/TPS. I will have to look and see it temp is part of it.

I really messed withe Caprice when I got rid of the AFM cam and installed an LS9 cam.
