PPE Xtreme Bar & Plate Duramax Transmission Cooler - Purple Clips 2003 2004 2005 Allison

The best way to increase the longevity of your transmission is to keep it cool. Heat is the transmissions biggest enemy. This extra large plate and bar style cooler raises the bar for Allison transmission coolers. This performance cooler installs in the factory location using existing mounting holes. Unlike earlier generation coolers, this cooler has welded on mounting, no adapters, brackets and misc hardware to fumble with. Customers should expect a temperature drop of up to 45 degrees vs stock coolers. This cooler will pay for itself because of increased fluid and transmission life.

Features:

• Massive 262 cubic-inch core volume, a 3.8x increase over the stock cooler for better heat dissipation
• 2.7x larger frontal area for increased airflow exposure and maximized heat transfer
• All-aluminum bar and plate construction for improved cooling capacity and pressure resistance
• Fully TIG-welded end tanks enhance strength and durability
• Delivers up to 45°F temperature drop, protecting against overheating and burnt clutches
• Includes new quick-connect fittings that work with stock cooler lines
• Retains all factory mounting points for a bolt-on installation
