ANY Honda owners out there who have been told they need a transmission flush every 25,000-30,000 miles? Or were you told transmission maintenance is based on codes? Did you do it? Issues with transmission now? Anyone not do it and car still okay? Need help - car under 64,000 miles and barely 3 years old - transmission went out and claim denied because no transmission fluid was ever changed. Dealership I bought the car from HAD THE CAR there at 28k miles and NEVER recommended a flush because “we do maintenance based on A1, A2 codes”. Trying to gather information for a case.
