8L90E Alto G3 Clutch Material. 4-5-6-7-8 C5 Power Pack with Performance Steels. Number 224758 2015-On.
Performance Steels start with standard Kolene and then run through our proprietary process of polishing to lower and reduce the range of the Ra value. The Performance Steel improves shiftability while maintaining the enhanced wear and fatigue resistance imparted by the Kolene process.
- Strengthened wear and fatigue characteristics
- Increased heat resistance – reduced hot spotting and warpage
- Increased lubricity for improved shiftability minimizing noise, vibration, and harshness (NVH)
- Prevents oil and friction material discoloration and contamination
