E4OD In-line filter for cooler line. Hard shell outer case prevents collapse and restrictions.  Magnet inside to catch metal debris.  An Oil/ATF rated filter at an affordable price.  The hard shell case allows easy in-line installation in the hose with ordinary hose clamps.  You don't need to pay $35-$50 for a dealer inline filter kit anymore.  2 hose clamps from a hardware store and this line filter can now protect your transmission from contamination and lube passage blockage and failure.    Line filters should be considered a must install.  Protect fresh rebuilds from repeat failure from missed contamination that can break loose from inside cooler and line passages.  Protect the small passages of new coolers from becoming blocked.  A dual installation will require 2 filters.  Hard shell outer case prevents collapse and restrictions, that flexable filters can't.  Shipping $7 US/48.
