50/52 Transaxle Cooler

My 50/52 transaxle has fittings for a cooler. But I'm wondering if I need some sort of pump to move the oil? Or is there an internal mechanism that moves the oil?

Not sure, but haven't ever heard they do. Something interesting though:

Re: 50/52 Transaxle Cooler

I had my G50-52 drilled for fittings with orifices in them so that oil would spray on all the gears and the ring gear by Powerhouse in '95. I used a large 40 micron filter before a Tilton oil pump that supplied 50psi to the orifices.

My Powerhaus supplied Ultima G50-52 is similar although uses a slightly later style oil spray bar, but Tilton pump is the same.
