Topic: Merc-o-matic fluid?

  I need to change the tranny fluid in the 53 but there seems to be some debate on what type to use as the type A the book says is no longer made. I guess all tranny fluids are NOT alike. Different resistance, how they affect the smoothness of shifting, etc. Some say type F is a good replacement, some don't, other brands are better that others.........

The 80 year old guy I bought the car from cannot remember what he used, and it's down about half at idle and I don't want to mix it, so I'm just going to drain it out and start from scratch and why I need some good advice.

  Dexron III is considered to be the best replacement for type A transmission fluid. It is what I use in my Hydramantic.

  Thanks Tom, and am I correct in that the car takes 9 quarts of AFT fluid?

  Here is a page from the shop manual for the drain and fill procedure.
