Okay I bought a MITYVAC m7000 so that I could use it to change out my diff and tranny fluid, but I can't get the damn thing to pump. I read through the user manual twice and all it talks about is a pressure fitting. But does not show it. I tried calling mityvac but they are closed today.

CAN ANYONE HELP?

 

If I'm not mistaken, that's a vacuum pump; I don't understand how you will use it to change differential and transmission fluid.

 

it's not designed to pump viscous fluids like gear oil, most people use them to change brake fluid

 

figured it out...you just remove a top piece then fit a hose to it now it pumps...all finished with the fluid swap...
