GM transmissions used in Axiom and Rodeos can have issues. Castrol IMV has good reputation among the Isuzu owners. Why change to DexVI, if IMV works great? I never go more than 30K or 4 years on one fluid change. IMV is a whole lot cheaper from my dealer than DexVI.
There are always people that will not deviate from manufacturer's recommendations, and that's OK if you are willing to pay the higher price. But go to a Honda forum and there are some that believe their tranny's will self destruct within minutes if anything but Z1 is used and that's just silly.
Meanwhile there are those that use a quality multivehicle ATF, such as Castrol, they enjoy smoother shifts and no price gauging from the dealer, to each their own, I guess
.
On the flipside there are people that believe everything they read on a forum as being more accurate than the manufacture. And how is Castrol IMV better than Dex VI, a very good fluid, or even Dex III in a GM transmission designed for Dexron? Castrol IMV is not less expensive or anymore available. Dex VI is available everywhere not just the dealer.
