6L80E High Performance Kolene Steel Module Alto Number .
Performance Steels start with standard Kolene Steels 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
