TransChill Transmission Oil Cooler Kits


Due to the extreme heat generated in an automatic transmission, an auxiliary oil cooler is an economical and efficient way to help protect against costly transmission repairs. Designed specifically to reduce excessive transmission heat caused by towing, carrying loads, driving in sand, snow, off-road and hot conditions.

Our TransChill Transmission cooler are an effective & economical way to keep the transmission at its optimum operating temperature. High efficiency turbulators in each tube direct the fluid for superior heat transfer. The unique plate & fin design allows for extreme cooling whilst the compact design is perfect for our vehicle specific mounting.

Automatic Transmission Fluid (ATF) cools, lubricates and cleans internal transmission components. When transmission components exceed 93°C (200°F) the performance of ATF is seriously compromised.

Subsequently the life span of the ATF, seals and internal components of the transmission are significantly reduced. Higher internal temperatures also increase the wear rate of the friction and clutch plates.

Direction-Plus™ transmission coolers can reduce the temperature of the ATF by as much as 33°C. A reduction of 11°C can double the life expectancy of the transmission, ATF and all internal components.
