Thanks guys, AGAIN, for all the helpful info. I do have the vintage shop manual. It is just as brief then as the new ones written now.
I just figured if it is original fluid, that maybe it needed changing. I'll check the level though. If it is dirty looking (check by putting my finger in it?), I'll change.
What type fluid is it? Typical Auto Transmission Fluid?
I got Grandpa's 47 Dodge Deluxe in 1995. He got it from his Dad back in 50. Grandpa didn't do much servicing of it (did change the oil and I started helping with that in 85), but it didn't get driven much since I came in the picture (I'm the son-in-law). Car only has 62K. Car has sat a lot. I'm going through all major systems just to check and ensure not needing attention.
Thanks for all your input!
