Guys, I currently have a '17 Silverado with the 6L80 6 speed transmission. I'd like to do a "Drain & Fill" & was wondering if I can use the is Mobil 1™ Synthetic LV ATF HP Fluid instead of the Dexron VI. Will this fluid mix OK & not Cause any issues? Truck has about 39k on it now & I would do a 2nd D&F some miles soon afterwards to get more old out & new in. Can anyone advise if these two fluids are compatible?
