My 2025 had zr2 stays stuck in a low gear. When rolling off a slow speed sustained hill truck down shifts rpm’s go up and tranny is under a load, when incline starts to level off and go back to giving it gas it will not upshift stays stuck in a low gear. The only way it will shift is to brake...
I ordered a HD ZR2 back in August from a large GM dealership in Idaho. I’ve gotten no help from Chevy or the dealer on why such a long wait, am l the exception almost 9 months and still no build date? I can put in a special order for a 25 mid June I hear, any insight would be helpful
