Mastering Heavy Towing with Your Chevy Truck: Optimal Transmission Fluid Change Intervals
Tyler SpanglerFor towing heavy loads with a Chevy truck, it's important to understand the differences between the 6L45 and 6L90 transmissions. The 6L45 is lighter, more budget-friendly, and suitable for moderate towing, while the 6L90 is designed for heavy-duty use with greater torque capacity and improved fuel economy. When frequently towing heavy loads, it's recommended to change the transmission fluid more often than standard guidelines, specifically every 15,000 to 20,000 miles for maximum protection. Additional tips include using synthetic transmission fluid, installing an auxiliary transmission cooler, regularly checking fluid levels, and avoiding extreme towing conditions. Installing a performance transmission pan can also help by improving heat dissipation. For specific recommendations and expert advice, consult Truck Transmission Specialist (TTS).
