For those that don't know, It should have a little floor plate on the passenger side (right) for access to the little filler stand pipe & dip stick. In 53, they changed to a dip stick tube in the engine compartment.
Just check on a level surface and fill to the full mark appropriate to the cold engine or hot engine just like the later cars. There is more info in the Merc-O-Matic manual than in the maintenance manual . I don't have a 1952 owner's manual but it may be in there. My 51 cars are both R10 overdrive models so I've never had to worry about it.
PS I went back to the M-O-M manual and it states to run the car in neutral for 4-minutes at idle then run through the gear selections to insure function and fluid distribution with the brake applied of course. Put the selector in park with the E-brake applied & engine in low idle and then check the fluid level. Fill to full mark an that's pretty much it. What confuses some about the 1P and later single range Ford-O's is that they start in Neutral and that low gear is manually selected. Low was for pulling when the car was heavy, otherwise the car could be operated in 2nd and high only.
