Specifically ones that see heavy track\/competition use. Transmission oil temperatures have a major impact on the shifting performance of your automatic transmission. If the fluid passes optimal temperatures you will start to see some delays in shifting. Sluggish shifting can be quite frustrating, but the real concern is the damage that can be done to the transmission when temperatures get too high. There are often cases where drivers don’t notice the change in shifting performance due to the gradual onset, but the damage is still being done slowly on a very expensive and important component.\u003c\/p\u003e\n\u003cp\u003eBy changing from the OEM single core design to a dual core, CSF was able to increase the overall volume by 194%. This design offers a drastic improvement in heat dissipation and increases the fluid capacity of the coolers by ~94%.

The wrong bit of debris flying through the front grille can quickly punch a hole in a cooler.
