rookie mistake
 

I think I just made a rookie mistake of draining the transmission (gearbox?) oil instead of the crankcase oil.

What to replace it with? 600W?

How much?

Re: rookie mistake
 

600 weight oil is right. You can get it from most Model A vendors. Fill it until oil starts to come back out the fill "pipe" on the side of the tranny.

And when you do drain and refill the engine crankcase put 4 quarts in then check the level on the dipstick...it is a 5 quart capacity but that is on a dry engine...about 1 quart is held in the dip tray.

And don't run your engine until the transmission has been re-filled....there are lots of moving parts in there that spin even if the car is in neutral and stationary....

I use 140w gear oil. But if you have 600w, use it......

To correct #2 response 600 W is a name, it is not 600 weight. Yes 140 weight is a close substitute as #3 response indicates..

Any good high pressure gear oil is satisfactory for spur cut gears and ball bearings if you want to get fancy use synthetic 85/140,it has superior properties to Dino oils due to consistency.

I wonder what you were thinking when the transmission oil was coming out ?

Re: rookie mistake
 

Any of the vendors will sell you an oil that will works fine.

If you want to get some elsewhere here is what works,

From a good post from Kevin in NJ,

I fill until full but these are from my notes;
600W Oil Usage Specifications

Transmission 1 pint
Rear End 1-1/2 Quarts
7-tooth Steering Box 7-3/4 ounces
2-tooth Steering Box 4-1/2 ounces
