53 Mayfair is a really nice Packard, best of luck with it.

Original trans fluid was Type A which is no longer available, most folks use Type F or Type FA which can be comixed with each other or with Type A, though it might be a good idea to drop the pan and clean, and drain all the old fluid and refill - capacity about 12 quarts if you drain the torque converter. Check fluid level with engine warm, idling.

If one can't identify the type of brake fluid is currently in the car, I would hesitate to guess and top if off with something that might not be compatible. Best bet is to drain and flush very thoroughly andf refill. Many folks use DOT 3 or DOT4, changeover to silicon requires a change of all rubber components, wheel cylinder seals, hoses, etc. Also some rebuilders of the booster do not recommend silicone for it. I personally use DOT4.

Hope this helps. Others will have more advice.
