Q: Will this work for a 2008 Suburban

a year ago
1 Answer
  • A: Dexron III is an older type of automatic transmission fluid (ATF) that has been superseded by newer formulations, such as Dexron VI, which is what General Motors recommends for most of its vehicles from the mid-2000s onward, including your 2008 Chevy Suburban. For the 2008 Chevy Suburban, the recommended ATF is Dexron VI, which is a synthetic fluid designed for better performance, longevity, and compatibility with modern GM transmissions (like the 4L60-E or 4L80-E commonly found in Suburbans of that year). While Dexron III might technically "work" in the sense that it could lubricate the transmission, it’s not ideal because: Compatibility: Dexron VI was formulated to meet stricter requirements for newer transmissions, offering improved viscosity, thermal stability, and friction properties. Using Dexron III could lead to suboptimal shifting or wear over time. Warranty/_specs: If your vehicle is still under any kind of service plan or you’re following manufacturer specs, sticking to Dexron VI keeps you in line with GM’s recommendations. Availability: Dexron III isn’t even widely produced anymore—most fluids labeled as "Dexron III compatible" are aftermarket substitutes, and their quality can vary. To confirm, your 2008 Suburban’s owner’s manual or a quick check with a Chevy dealership would specify Dexron VI for the transmission. If you’re topping off fluid, use Dexron VI to avoid mixing issues. If you’re doing a full flush, definitely go with Dexron VI. Dexron III might function temporarily, but it’s not the right choice for your 2008 Suburban. Use Dexron VI instead
