Sorry bud but you are wrong on this. It will downshift very aggressively In TH mode (RPM limited) with the exhaust brake in full on mode when a couple things are met. One the truck has a predetermined deceleration rate and you can't be slowing down any faster than that rate. The other is you HAVE to put your foot on the brake pedal (don't have to apply brakes just light your brake lights) for the truck to know that you want to slow down. It will then begin to downshift and apply the amount of exhaust brake needed to decelerate at the programmed rate that is in the computer. I have seen my exhaust brake gauge as high as 150 braking hp. When you have it in auto mode it will do what ever it needs to do to hold a curtain speed but once it slows to that speed it will adjust to keep to that speed instead of like the full on mode that will continue to slow the truck until around 20 mph.

I agree with you that FLT did not get the full effect of the Ram's exhaust just because of the way they conduct their test. They consider brake touches as a deduct even though you don't have to apply brake pressure you just have to touch the pedal for it to work.

Thanks for that. I was wondering how RAM's two-stage EB, as described by ShinerB, interacts with tow/haul. I guess it also interacts with Cruise Control as well to reduce speed downhill?

Sorry, I can't give you exact on the Cruise Control interaction because I don't use my cruise when I'm towing. I would believe it will interact with the exhaust brake on Auto mode just because the auto mode is programmed as a speed assist. Full on mode is a brake assist so it senses how fast the truck is slowing down and senses input from the driver as to how fast he/she wants to slow down buy applied brake pedal pressure.
