Holden RG Colorado/Trailblazer 2.8LT HPD Transcooler Kit

Description

Holden RG Colorado/Trailblazer 2.8LT HPD Transcooler Kit Overview

The Holden RG Colorado/Trailblazer 2.8LT HPD Transcooler Kit keeps your transmission operating within safe temperature ranges, even in tough towing and off-road conditions. Factory transmission cooling often relies on the radiator, which overloads the cooling system and causes high oil temperatures. The HPD transcooler provides a dedicated cooling solution, improving reliability and performance for your 2.8L Colorado or Trailblazer.
