The Mishimoto transmission cooler for the 2010-2024 (fifth-gen) Toyota 4Runner 4.0L keeps fluid temperatures in check when towing or working the trail. It's designed to run alongside the stock in-tank cooler, adding cooling capacity without compromise, and its tube-and-fin core with high-efficiency internal fins maximizes heat transfer to extend transmission life and reduce the risk of costly failure. The kit includes everything needed for installation — pre-cut hoses and fittings that connect to OEM or Mishimoto components, with SAE J1532-rated lines for leak-free connections — and a robust powder-coated finish for harsh environments.
