Fluidyne High Performance Allison Transmission Cooler GM Duramax

The Fluidyne High Performance Allison 1000 Transmission Cooler (also called a transmission fluid cooler or automatic transmission oil cooler) is an upgrade for GM 6.6L Duramax trucks with the Allison transmission. Towing, hauling, and hot-weather driving all raise transmission fluid temperatures. This bar and plate cooler adds heat-exchange capacity over the factory unit.

Key Features:

• Over 4x the heat exchanging capacity of the stock cooler
• Aerospace-grade aluminum bar and plate construction for cooling capacity with low pressure drop
• Densest fins-per-inch layout with a proprietary fin design
• Fully welded internal splitter plates keep the hot and cold side fluids from mixing
• Powder-coated finish with a proprietary heat-wicking compound
• Direct bolt-in replacement that uses the factory mounting locations
• Limited lifetime warranty from Fluidyne

Fluidyne is known for high-performance cooling products. This cooler helps keep transmission fluid temperatures down under heavy use, which supports transmission durability and consistent performance. Select the variant that matches your application.
