Built with top-level performance and heavy duty use in mind, PPE’s Stage6G will handle whatever you can throw at it.

The Stage6G Transmission Kit is the strongest transmission upgrade kit that PPE offers. Thanks to the triple clutch converter, valve body recalibration kit (recalibration kit does not change shift points, only increases clutch holding power), converter flow Valve, upgraded C1, C2, C3 and C4 clutches and 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.
