Chevy Silverado 2500HD 6.0L
I have a 2018 Chevy Silverado 2500HD WT (4x4, Crew Cab, Long Bed) with a 6.0L engine. I was told the rear end gearing is 4.10. My question is when I pull my TT (26 feet and just under 9000 pounds) up a Mountain Pass my rpms tend to fluctuate between 4000 and 5000 rpms to maintain speed. Is it safe to run my rpms that high? Should I install an aftermarket transmission cooler to keep the transmission temp low? Any suggested modifications to gain power?2KViews0likes6Comments
