Purchased a really nice Model M a month ago. Transmission had water contamination, as expected.
I drained the milky fluid out, flushed with 1 gallon of diesel oil and drained that, added a gallon of motor oil to act as a flush. Still had quite a bit of contamination when drained.
Let sit for 2 weeks with drain plug open.
Added 1 gallon of GL-4 85/90 wt gear oil. Drove it around - still milky and some foam apparent.
Is there more than one drain plug? Per my factory shop manual, there is only 1 drain plug. And, the capacity is 6-1/2 quarts. Cannot add more than 4 quarts before full to the filler plug.
Looks like I will drain it again. Looking for suggestions. Maybe pull the shifter cover? Seems like 2-1/2 quarts of crud still in there, or I am not getting everything out.
Quality GL-4 isn't cheap, and I'd like to figure this out before buying more fluid.
