Stage4 Transmission Upgrade Kit With Torque Converter
50 States Emissions Legal (E.O. D-701-18)
PPE’s Stage4 transmission kit is our entry-level kit that’s perfect for drag racing, sled pulling, towing or even daily driven use. This kit works extremely well for a stock truck but was engineered to handle a Duramax engine that has been equipped with multiple high performance modifications, such as performance chips, oversize injectors, and/or small nitrous kits.
This kit includes PPE’s triple clutch converter, valve body recalibration kit (recalibration kit does not change shift points, only increases clutch holding power), converter flow valve and upgraded high-friction C1, C2, C3 and C4 clutches with Kolene steels.
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.
- Billet Cover Billet Stator (128010305)

Kits vary by quantity, thickness and material based on your specific transmission needs. Call to discuss your transmission project to ensure you get the most from your build.
