mercon V ATF ?
Am going to refill my M50D R1 trans with fresh fluid. Can Mercon V be used instead of regular mercon trans fluid? I take it mecon V is sort of an synthetic based fluid?

If you want to go synthetic, go ahead, but make sure the fluid itself is the same type.
Honestly...there are some rumors that synthetics promote leaks, so I'd recommend staying with Mercon/Dexron 3. The good old stuff. You have done the mod to seal the shift rail plugs on the tranny, correct?

We try. Lots of people come asking for info, I only wonder how many don't ever join, just poke around, find the info, and scoot along. I did it for about two days then realized this was home to me lol.

Mercon V is actually a synthetic blend. For the manual tranny either Mercon, or Mercon V should do ok, but for the automatics, stay exactly with whats recommended, DO NOT use multi-purpose ATFs!!!

If you want a synthetic ATF, you can get a Mercon/DextronIII in full synthetic. That's a much better way to do what you're trying to do.

(1) able to handle the "slippier" Mercon V in their original design without any issues,
(2) have been rebuilt with upgraded clutch components that can now better handle - maybe even utilize more fully - the different properties of Mercon V, or,
(3) are out of service by now in any case.
