Will this fit/work on 2004 w20 chassis? ( Steven Carter, 06/20/2021 )

Hi Steven,

    That VIN calls for the W8000540, however that has been discontinued. We offer the WH000540 as an alternative; you just have to use an external trans cooler with it. We offer two of them, WH000540C with out an electric fan, and the WH000540CF with a fan.
