Product Details
✓DROP TRANSMISSION TEMPS BY UP TO 20°F:Take control against transmission heat. This upgrade kit replaces the stock thermal control valve to promote increased cooler flow, lowering average operating temperatures. This helps combat fluid breakdown and supports better heat management during demanding conditions like towing.
✓PRECISION ENGINEERED UPGRADE KIT: This kit is designed as a performance upgrade for vehicles equipped with 6L80, 6L90, 8L90 & 10L90 transmissions (common in 2014+ GM trucks and SUVs). A direct bolt-on solution that requires no modifications, ensuring a perfect fit and reliable performance.
✓INSTANT COOLER FILLING & ACCURATE FLUID CHECKS: Our kit's integrated safety bypass enables near-instant cooler filling. This design allows for precise cold fluid level checks, so you can avoid the common pitfalls of over-filling or under-filling.
✓BUILT WITH HIGH-QUALITY MATERIALS FOR LONG LIFE:Invest in reliability. Manufactured to strict quality standards using durable materials, this valve is built to withstand the harsh environment under your hood. It delivers stable performance and long-term reliability, protecting your transmission investment for years to come.
✓ENHANCE PERFORMANCE & EXTEND TRANSMISSION LIFE:This isn't just a part—it's preventative maintenance. By maintaining consistently lower temperatures, this upgrade reduces wear on clutches and seals, enhances shifting performance, and significantly extends the overall lifespan of your transmission, saving you from a costly rebuild down the road.
