PPE PERFORMANCE TRANSMISSION COOLER 124060300 | 2001-2010 6.6L DURAMAX LB7/LLY/LBZ/LMM

Protect your transmission from excessive heat with the PPE Performance Transmission Cooler. Designed as a direct bolt-on replacement, this upgraded cooler lowers transmission fluid temperatures by an additional 20 to 30 degrees compared to the factory unit, helping extend fluid life and improve transmission durability under demanding conditions.

Featuring a larger cooling surface area that provides approximately 60% more heat dissipation than stock, this cooler is an excellent upgrade for trucks used for towing, racing, or heavy-duty driving. It is also highly recommended for vehicles equipped with performance transmission upgrades that increase line pressure and generate additional heat.

By maintaining lower and more consistent transmission fluid temperatures, the PPE Performance Transmission Cooler helps reduce thermal breakdown of the fluid while promoting longer transmission service life.

Features:

• Direct-fit replacement
• Reduces transmission fluid temperatures by an additional 20–30 degrees
• Approximately 60% greater heat dissipation than the factory cooler
• Helps extend transmission fluid and transmission life
• Ideal for towing, performance, racing, and heavy-duty applications
• Recommended for transmissions with increased line pressure or performance upgrades

Important Note:

• Verify the color of the factory transmission cooler line retaining clips before ordering. Orange clip and purple clip applications use different cooler part numbers.
