Hello all. Just joined and looking for advice from experienced tuners. I plan on tuning my 2025 ST and understand replacing spark plugs (to NGK Ruthenium) and engine oil (filling to 6.5 qts) are a must. I plan on a Livernois 93 Tune and will generally continue to use my ST as my daily driver. I'm seeing mixed advice regarding transmission fluid and filter change. Is this a must as well?
