The 455/ 485 are both same torque rating @1650. The 485 just holds peak torque for a little bit longer and produces more between 1400 and 1700 RPM. Transmission calibration changes won't produce more torque, just hold RPM higher for more HP. L downshifts as soon as possible to keep RPM high. You can use L or put in M and downshift yourself.

 

How can we check to see what my tranny is at, 1650 or 1850?
So basically first step is change the tranny to performance mode and see how I like that mode?

 

Post last six of VIN and I can look it up. Yep that would be first step.

FO16E310C-LAS transmission. So 1650 is torque rating. Surprised to see wheel size of 24.5, but was low profile tires.

 

Well its back to 22.5 tires. I swapped the tires over. So to get the best Pull up the hills, my best option or options is First change the Tranny to a Performance Mode.
then if there anything else?
without changing the rears?
Oh and i did uprate her to 485hp

 

Also was wondering, and this may be a dumb question, but is there a way to change the torque rating from 1650 to 1850 in the truck? I thought the Ultra Shift was either as well as the MX so is not just software?

 

1650 is as high as they go on the ten speed LAS models. Usually difference is in hard parts like bearings, gear heat treatment and oil pump setup.

 

Oh okay so what options do I have so I can climb the hills better and at a more constant speed without changing the Rears and after I change the setting in the tranny?
Do I have any other options?
