Wondering the line pressure of the auto tranny on a 3/4 ton truck or any auto?
Out of trans and comming back from the cooler. is it related to the rmp like engine oil if so what is the max?

Thanks

I've heard 17 psi going to the cooler. I've never checked it myself. I don't know if it has any relation to RPM or which gear you're in. Which transmission are you talking about, 700R4?

Asking about a 48RE behind a Cummings Dodge.
I wanted to know about some lines for a in line filter, The pressure should be low enough to use some standard hose and fittings.

Thanks
