Question:

I have a 2011 Tahoe with factory transmission oil cooler. Is there a benefit to adding a supplemental cooler rather than replacing the factory installed original? Secondly, what size fittings are needed so that no line modifications are needed? Thanks

Expert Reply:

Adding a supplemental cooler to your factory transmission cooler is what is recommended in most cases because the factory cooler is most likely working fine and adding a secondary cooler in line will just assist in the cooling already taking place.

I recommend the Derale Series 8000 Plate-Fin Transmission Cooler Kit w/Barb Inlets # D13503 for a good option, but the # D13403 is an even better and more efficient option. For either installation, you will want the Derale Snap-In Radiator Adapter Fitting for GM # D13035 to make an easy connection with the snap fitting.
