Do you have the 6 speed? and what gear does it down shift into when the exhaust brake kicks in? Mine was going from 6th to 2nd, and I just had it changed to 4th gear. I find it doesn't hold me back like the 2nd gear did, causing me to use the brakes more. And, it does allow the truck to gain speed going down steep grades???I manually down shift to 3rd as I need it. How about you?? I'm towing 17,000 lbs.
