Stock spin-on transmission filters come up short. PPE recognized the need for better filtration for the hard-working Allison 1000 and 2000 transmissions, so a superior filter was developed which addresses limitations of the standard shorty filter.

Duramax Premium High-Efficiency Spin-On Transmission Fluid Filter
Inside the PPE Double-Deep Spin-On Filter is 2.72 times more filter media surface area. This increased surface area allows improved fluid flow and filtering.

The PPE Double-Deep Filter actually traps particles down to 15 microns, that is half the size of what the standard spin-on filter catches. These improvements help create a cleaner flow of oil to vital internal components, resulting in smooth, more responsive shifts.
