A complete pan service kit built to OE fitment for the Aisin AW450-43LE automatic transmission, compatible with Isuzu NPR and NPR-HD diesel trucks from 1998 to 2006, as well as Chevrolet and GMC W3500/W4500 Tiltmaster and Forward trucks equipped with the same transmission. Includes one transmission filter for the Isuzu 4.8L diesel application and one nitrile pan gasket for the A440F/A442F pan. Replacing both together helps maintain clean fluid flow to the valve body and internal components, addressing common symptoms like hard shifting, hesitation, and slipping, while the new gasket helps stop pan leaks from a worn factory seal.

Add Lubegard automatic transmission fluid additive to your fresh fluid for improved heat resistance and reduced wear between services.
