How many actual miles are on the car? It may be overdue for a rebuild. One of the worst things about these Ford-O-Matics is old dried out and worn rubber gaskets and O-rings, especially the front converter O-ring and the converter hub O-ring. If the trans sat for long periods of time, you know they had dried out, but they may have cracked which means there will be little annoying leaks all the time.
Years ago I had a lot of trouble finding a reputable and professional shop whom I could trust with my Ford-O-Matic rebuild. I passed up three places in different towns whom I felt un-easy with after talking to them in person. Finally found a shop in a different town that is very good, trustworthy and does quality work. Eventually, if you search, you can find somebody.
Miliage on it based off records I have is 155,000 miles. Transmission was serviced Aug 2 1963 at 75,600 miles. My records don't show another transmission service since 75,600 miles and the car is currently on 55,000 miles on the odometer. Guess its about time to do another service anyways. That means right now transmission is at 79,400 miles. Guess I will give it a go doing a transmission service.

I know gaskets do dry out and leak but as of now ive been running the car the last 4 years and it hasn't leaked any fluids out of it out side of the transmission leaking out of the driveshaft yoke itself as the plug on the back side was missing.

Only other leak I have is coolant, one core plug is rotted out where it drips but its not bad enough that I cant run the car. I like to think the car being stored in a open shed with a dirt floor that it helped preserve the vehicle. I brought the car home and it had ruby red transmission fluid in it. So I don't know doesn't mean there cant be some kind of internal leak.

I just cant say on local transmission shops. I just cant trust any of them as ive seen way too many of them do bad work.
