2020 C1 of the Year Finalist - Unmodified
Powerglide
'60 equiped with a Powerglide date stamp July 8, 1958. Today was the first time in 3 months I drove the car. There was a puddle of transmission fluid on the floor.
I'm aware the car needs to be driven more frequently.
My question is what is the correct way to check the fluid level. I have read engine running in neutral, engine off in Park. What is the correct procedure.
Thanks, Bud

Found this on the Chevy Forum…I am assuming you are referring to a cast iron glide. I had one in my 55 Nomad and tried to remedy that very problem for over 30 years. My final solution was to take it for a ride every Sunday. No more leak.

Next time you anticipate a dry dock for the C1, jack it up in the rear and "start engine/run it through the gears" once a week. Dried out seals (including Navy Seals) need a good lubrication, on a steady basis, to function as designed.

It's been almost half a century since I had a C1 with an "Ironglide". I seem to remember that transmission is almost "all torque converter". I'm wondering if, from sitting, the converter is draining back into the pan and overflowing out the vent (I just can't remember where that vent is but maybe the tail housing?).

We must remember that automotive engineers designed the transmissions with the assumption the would be used daily, every other day, or at least weekly. The transmission pan and gasket, speedo gear seal, selector shaft seal and filler tube seal were not intended to hold back the entire contents of the transmission, which is what happens when the torque converter slowly drains its contents back into the transmission. Most old transmissions do this given time, Powerglides, Hydra Matics and Torqueflight 727's do it more. I have a 63 Ford CruiseO (MX) that doesn't leak a drop. How much they leak is a function of the condition of said seals and how often the car is used.
