6L80/8L90 No Cut Cooler Kit

6L80 Transmission Cooler Kit – With AN Fittings & Bypass Delete

Upgrade the cooling performance of your 6L80 transmission with this premium cooler kit. Designed for durability and efficiency, this kit eliminates the factory bypass block, ensuring your transmission fluid circulates through the cooler 100% of the time. This constant flow helps reduce operating temperatures and extend the life of your transmission.

Key Features:

Precision-engineered AN fittings on both inlet and outlet sides for secure, leak-free connections.

Bypass delete block ensures continuous fluid cooling, preventing overheating during heavy loads or towing.

Improves reliability and longevity of your 6L80 by maintaining consistent fluid temps.

No-Cut solution with performance in mind – ideal for daily drivers, tow rigs, and performance builds alike.

Why It Matters:
The factory bypass block limits cooling until high temps are reached, which can lead to early wear. By deleting the bypass, this kit guarantees your transmission stays cooler, longer — no matter the driving conditions.
