Where EXACTLY is the drain plug on this transmission (four-bolt pan)? I don't have the MBZ transmission manual and the Haynes manual shows a plug (forward of the pan) where there isn't anything resembling a drain plug on my transmission.
The best that I can find is a funny looking plug (half-moon slotted) to the rear of the drain pan. Is this the drain plug, and if it is what special tool is required (or what can be jerry-rigged) to remove it?
The alternative is to loosen the transmission fluid line couplings, but that drains only about 3 of the 5 quarts.
Is Dextron III ATF fluid okay (owner's manual says to use "specially tested and recommended ATF, Dextron type") or should I be using something different than Dextron III fluid?
