I have a 2019 RST with the L84 V8 8 speed with about 75k miles. No issues, other then the transmission being a bit rough. A transmission fluid flush helped with that, though now I feel more of a vibration when DFM kicks in than I remember. Is it worth disabling the DFM to help prevent lifter failure? Or am I overthinking that? Harder to find information on failures for this engine before the 2021 model failure. Thanks!
