So, 5 days after delivery of my 2025 Duramax 2500HD with 423 miles, the Mrs noticed a stain on our driveway. She initially thought it was from our Polaris RzR. After moving the truck to its usual spot, a short time later another spot. A quick check confirms it’s tranny fluid. Consulted the dealer after the holiday and determined it was on to drive. Dropped off and got the call later that day all fixed. Input shaft seal. There is a TSB for 2022-2024’s, appears the same issue, but hasn’t been updated if it is. Forty miles and all seems well 🤞🙏🏻
Other than this glitch the truck is all good…
