I don't remember, but I think I use my wrench that is 22mm on one end and 24mm on the other.

Doesn't look like it. On MINE anyway 22mm will fit neither although all I want to do is open the fill one to top off. Thanks though.

I meant it's probably the 24, but I don't remember so you really don't have a definite answer yet.

Cresent wrench

Those should be called "bolt head rounders"

well if you buy a good one they work well... I just changed the fluid in my M5OD and thats what I used... the trick is to not over tighten the plug... make them just snug...

I used Castrol Syntec 5w-40 synthetic

The only crecent I have isn't big enough. But yes it is what I would use and maybe did borrow last time. I thought our transmissions called for type F or Dex/Merc. Which really to me should be just as good as motor oil. My Honda 5 speed calls for the same cracnkcase as transmission I belive or it is a motor oil very similar in weight. As for the rear end of the Honda its a "Double Pump" hydraulic transmission fluid. Kinda neat how they did that. Front wheel drive, with clutches between the front pinion gear and drive shaft. When front end spins (deiveshaft spins faster than pinion gear) an imbalance in pumped pressure is created and clutches engage, which engages the rear end. They call it Real Time 4wd. Not a mud toy really. But interesting concept.

Dextron/Mercon.

Anyone ever find out the exact size of the fill/drain plugs?
