Howdy y'all,
I just got in my 2015 Silverado 2500HD LTZ and am having trouble with my transmission in my low gears. When I accelerate from a stop my gears don't catch until I'm running between 1,500-2,000 RPM. The truck also does not register when I drop from drive to manual. No issues when accelerating in a higher gear. Just don't know what the issue could be from. Maybe my timer?
