I’ve been hearing a high pitch whining when accelerating semi aggressively. From a stop if im accelerating quickly you can hear it make a whining noise until it gets out of first gear. On the highway if I’m passing, I can hear a faint whining noise in the higher rpms(5k-6k rpm)in any gear but the noise is not apparent in the lower rpm’s when cruising . I’ve been noticing it more and more lately and wondering if anyone having similar issues. I do in fact experience an occasional rough down shift when stopping but that seems common. This is on my 2019 Grand Cherokee 3.6 altitude 4x4 with under 10k miles.
