Looking for some advice here, I jest spent over $2300 to have the M5OD rebuilt in my 2003 Ranger. The shop has requested that I stay with a Dexron III/Mercon fluid. I would typically have installed some form of MTF like Synchromesh and have even used Low-Viscosity Hygard from John Deere in this transmission in the past. The issues requiring a rebuild were not related to a lubrication issue per the shop other than likely a lack of maintenance and abuse from the fleet that owned the truck for the first 200k miles of it's life. The shop uses a Citgo ATF that they buy in bulk "because it's cheap and works" per the owner.
Do any of the available ATFs stand out above the rest in this application? I keep Schaeffer 204 here and have access to Walmart, Oreilly's, anything on the internet, and our local farm Co-op (MFA). I just got home from a 1100 mile road trip and want to change it soon.
