Heat is what kills an automatic: towing and heavy loads break the fluid down, and once it is degraded the clutches glaze and the converter follows. A cooler that is plugged, leaking, or holding debris after a transmission or converter failure has to be replaced or properly flushed before a rebuilt unit goes in, or the new transmission inherits the same contamination.\u003c\/p\u003e\u003ch4\u003eWhat's Included\u003c\/h4\u003e\u003cul\u003e\u003cli\u003ethe transmission oil cooler and\/or its lines, fittings and O-rings as specified\u003c\/li\u003e\u003c\/ul\u003e\u003ch4\u003eFitment\u003c\/h4\u003e\u003cp\u003eFits Chevrolet, GMC trucks equipped with the 3.0L Duramax diesel engine, 2017-2020.
