The PPE Stage5R Performance Transmission upgrade kit is built to transmit your engine's high-horsepower output through the Allison transmission. The state-of-the-art friction material withstands high heat and high temperatures to produce greater torque capacity and optimize performance. Optimized for heavy-duty vehicles and high-stress conditions that call for improved performance and increased holding power.

Includes Valve Body Recalibration Kit (recalibration kit does not change shift points, only increases clutch holding power), converter flow valve and upgraded C1, C2, C3 and C4 clutches and robust steels.

This kit is also available as a complete, ready-to-install transmission.

NOTE: A $200 converter core charge is included in price if bought with converter, reimbursed upon return of good core components to PPE. PPE product finish will vary.
