Trans Fluid Question

What about 50% STP in the ******?

New to the forum and the Model A world. I had problems shifting after changing the oil to Mac's 600w oil, When I removed the shifter I saw lot's of foam? I had only run the car for about a minute to get it onto place to do the work. I ended up putting Amsoil SAE 250 into the trans - so far so good...I haven't seen this mentioned yet...Maybe I have missed something - feed back is appreciated

I use the 680 oil from either Chevron or Mobil. I use it in my the steering box, trans, and differential. Never any foam or problems. My trans shifts well with the 680...

...I would advise against using Grampa's coffee as it tends to eat the gears.

And only add sawdust shortly before the sale. It doesn't last long......
