Isuzu DMAX / MU-X 2012-2020 HPD Transcooler Kit

Description

Overview

The Isuzu DMAX MU-X 2012–2020 HPD Transcooler Kit provides superior transmission cooling for vehicles that face heavy-duty demands. When towing caravans, boats, or trailers, transmission heat quickly builds up and can lead to premature wear. This HPD upgrade ensures that your transmission fluid stays within safe operating limits, even under extreme conditions. Drivers who regularly tow, tackle off-road tracks, or operate in hot climates rely on this kit to protect their automatic transmission. Its efficient bar and plate design delivers consistent cooling performance while maintaining strength and durability.

Unlike many factory systems that use small heat exchangers or rely on the radiator, the HPD transmission cooler works independently. This separation prevents excess heat transfer between engine and transmission, reducing the chance of overheating when both systems are under stress. By controlling transmission temperatures, the kit helps preserve fluid quality, extend service intervals, and improve long-term reliability.
