Frequently Asked Questions

What makes the CDT Level 3 6L80 clutch module better than stock components?

Our Level 4 6L80 performance clutch modules offer up to 50% more clutch apply area than OEM parts, using premium friction materials like G3® and High-Energy. This improves torque handling, reduces slippage, and significantly increases transmission durability under high-load or high-horsepower conditions.

Do I need to upgrade the 4-5-6 hub and intermediate shaft when installing this clutch kit?

Yes. To properly install the Level 3 4-5-6 clutch module, you must use CDT’s Billet 4-5-6 Clutch Hub and Intermediate Shaft (part number 104680-45-P). The required 45-tooth clutch plates are not included with this Clutch Module and must be purchased separately. 104680-45-P billet shaft is designed specifically to work with 45-tooth clutch plates, ensuring optimal performance and durability in high-powered applications. 

Can I use this 6L80 clutch module kit in a daily driver or towing vehicle?

Absolutely. While this kit is designed for performance builds, it’s also ideal for towing, off-road, or high-mileage daily drivers looking for increased reliability and smoother shifts. The extra surface area and premium materials reduce heat buildup and wear over time.

How do CDT clutch modules compare to other aftermarket 6L80 transmission parts?

CDT clutch modules are engineered with precise machining, premium friction and steel plates, and enhanced piston designs to outperform most aftermarket options. Our focus is on heat resistance, clutch engagement quality, and long-term reliability in high-demand environments.

Will this clutch kit fit my specific GM vehicle with a 6L80 transmission?

These clutch modules are compatible with most GM vehicles equipped with the 6L80 transmission, including trucks, SUVs, and performance cars from 2006 and up. For specific fitment, always check your vehicle’s transmission code or contact CDT support for verification.

Recommended Transmission Tools

  • Transmission holding fixture
  • Calipers
  • Dial Indicator Set
  • Bushing Drivers & Arbor Press for Bushing Installation (Bushings should only be replaced as needed)
  • Sealing Ring Protector and Sizer
  • Various Clutch Spring Compressors
  • Output Carrier/Shaft Lifting Tool
  • 1-2-3-4 & 3-5-R Clutch Housing Installer
  • Large Snap-Ring Pliers
  • Pump Alignment Tool

Misc. Transmission Information

Upgraded Parts: If you have an early pump cover (stator) that does not utilize anti-rotational tabs on the sealing rings or an early 1-2-3-4/3-5-R clutch housing that does not have the matrix stamp, you will need to install a factory-upgraded pump cover and clutch housing.

Transmission Tuning: Please understand that proper tuning of the TCM and ECM is mandatory. All 6L80/90’s are torque-based shifted units. The torque signal is calculated through the ECM. Therefore, transmission performance and longevity are directly dependent on the delivered torque signal that’s calculated in the ECM. If this is not done properly, you will experience premature transmission failure. We also do not recommend maxing out pressures or deleting torque management completely because it will cause seal failure and/or hard part breakage.

Flushing Cooler & Lines: We cannot stress enough the importance of flushing the transmission cooler(s) and lines, even if they are new. We recommend using a Hot Flush Machine Flush Machine or something comparable.                                      

Auxiliary Cooler: You need to install a stacked plate auxiliary transmission cooler (not a tube and fin style cooler) rated for 25,000 GVW. The ideal operating temperature for this transmission is 180°or less. These transmissions tend to run very hot, so the cooler will lower the operating temperature and recovery time, which in turn will extend the life of your transmission.
