While the OEM Transmission Cooler is adequate for the G8X in stock form, it starts to come up a bit short on modified/tuned vehicles. 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.

By 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%. Utilising CSF’s AC Condenser Technology, a 1-Row Super-High Pressure 16mm 9-Channel Microtube design optimizes oil flow and offers maximum surface area contact. These features combine to offer the best possible heat dissipation from the system.

CSF knows the kind of punishment the front of a car can take on or off the track. The wrong bit of debris flying through the front grille can quickly punch a hole in a cooler. Because the Transmission cooler sits at the very front of the centre cooling stack, it is quite vulnerable to damage. In addition, “open face” race-style grilles have become quite popular on the G8X. These grilles can add to the risk of debris passing through. The factory grille is the only form of protection for the OEM transmission cooler. However, this still isn’t the level of protection many race teams and enthusiasts are comfortable with. To address this concern, CSF has incorporated a replaceable rock guard to keep your cooler safe and your G8X running strong in the event of debris making it through the front grille.
