Introducing STL-8L90 SHUDDER~SOLUTION™
The STL-8L90 SHUDDER~SOLUTION™ is a game-changer for all 8L series transmissions (2007 and up). This comprehensive kit addresses the persistent shuddering and chattering issues that have plagued 8L units.

Key Features of the STL-8L90:
- Stops shuddering and chattering in all 8L series units
- Installs easily without removing the transmission assembly—most installations can be completed from the bottom
- Can be applied even in units showing early signs of shuddering
- Utilizes existing fluid for optimal performance—no need for fluid replacement
This kit is designed to correct design oversights that lead to failures, ensuring that 8L units not only perform better but also maintain that performance over time.
