Part# 12803420X

PPE’s Stage 4 transmission kit is a 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 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.

Includes:

  • C1, C2, C3, and C4
  • Valve body recalibration kit, boost valve, pump shim and gaskets

Optional:

  • Optional C5 Clutch Kit
  • The optional C5 clutch kit is built to handle heavy duty towing. The C5 clutches improve first gear, reverse and park.
