Synthetic Tranny Fluid
I will be changing the fluid in my dad's 2002 PSD auto 4x4 CC dually soon, and he is asking about synthetic transmission fluid. We have always used dino Dexron III/Mercon because the owner's manual states to only use that fluid and NOT MERCON V OR DUAL RATED FLUIDS. I have also heard of people trashing the clutches in the tranny from using Mercon V. Now, my question is: Is it OK to use Amsoil Universal ATF or Mobil 1 Synthetic ATF even though they are both dual rated Mercon/Mercon V fluids? Has anyone been running either of these in a stock tranny for an extended period of time? Thanks guys!
