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 C4 clutches with Kolene steels.


  • C4 includes: 6 friction plates, 5 steel separator plates


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.
