When should I consider getting a transmission flush, particularly in the context of maintaining optimal performance and longevity of my vehicle? Is there a specific mileage that serves as a benchmark for such a procedure, or should I be vigilant about any particular symptoms that might necessitate this service? What role does the type of driving I engage in play in determining the frequency of this maintenance task? For instance, does stop-and-go city driving require a different approach compared to long-distance highway travel? Furthermore, how does the manufacturer’s recommendations factor into this decision-making process? Are there certain indicators, such as unusual noise or slipping gears, that should prompt immediate action? What is the potential downside of delaying a transmission flush, and could neglecting this maintenance result in more substantial issues down the line? Ultimately, what comprehensive factors should I weigh to arrive at an informed decision?
