Design Development and Testing 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.
