This is a fix for the commonly leaking transmission cooler hoses for 2003 Chevy, and GMC trucks equipped with the Allison 1000 transmission behind the 6.6 liter duramax engine. These are made out of Gates 1/2" id braided hydraulic hose, rated for a minimum of 2000 psi, and Gates Megacrimp hose ends. These hoses will handle the pressure and temperature that the factory hoses will not. Included, is everything to make the conversion possible, except for the tools. I also included detailed instructions, which includes a list of required tools to perform the job properly.
If flow,or temperature is a concern for you, consider the 5/8" hoses that we sell. Examples: heavy towing, chipped ecu, larger turbo, propane injection, or modified transmission.
