The Executioner
Four-digit horsepower with a 1-year 12,000-mile warranty — the top of the ladder, custom-built to 1,500 HP on request.
Rated for power. Built to hold it.
When you're making four-digit power, nothing off a shelf survives. The Executioner is a full custom build: billet input and output where the platform demands it, the maximum clutch stack, a competition valve body, a high-volume pump, and a deep pan and cooler package. Rated to 1000+ horsepower and custom-built to 1,500 on request — all backed by the same 1-year 12,000-mile warranty. This is the transmission for drag-and-drive, pro-street, and big forced-induction combinations.
What’s inside every Executioner
Real parts, listed plainly. This is the difference between a transmission that’s rated for power and one that actually holds it.
Enhanced Clutch Capacity
Upgraded high-energy friction materials with added clutch count where the platform allows — far more holding power than factory spec.
Hydraulic System Improvements
Performance valve-body work sharpens shift quality and raises line pressure for firm, consistent engagement under load.
Reinforced Hard Parts
The common OEM failure points for your transmission family are replaced with stronger, upgraded components.
Performance Pump Upgrade
Improved fluid control and pressure stability to support the extra horsepower and towing demand.
Complete Performance Rebuild
Every unit is fully disassembled, cleaned, inspected, and rebuilt with an all-new master overhaul kit — seals, gaskets, rings, filter, and steels.
Custom Shift Reprogramming
Your valve body and, where applicable, TCM tuning are dialed in for firm, precise shifts matched to your power level and use.
Heavy-Duty Clutch Pack
Additional high-temp clutches for a meaningful jump in torque capacity over the entry build.
Hardened Center Support & Shell
The single most common high-power failure point is replaced with an oversized, hardened piece.
Race-Spec Clutch Stack
Maximum clutch count in the high-load drum — many more frictions than the factory ever ran.
Billet Servo (+30% Apply)
A billet servo replaces the cast factory piece for stronger, more consistent band apply under hard shifts.
Cold-Treated Planetaries & Sprag
Heat-treated multi-pinion planetaries and an upgraded sprag absorb the shock loads that break stock gearsets.
Billet Input & Output Shafts
Billet shafts replace the factory pieces at the points that twist and break under four-digit torque.
Competition Valve Body & Manual Options
A full competition valve body — with transbrake or manual/pro-tree options available — for the quickest, most repeatable shifts.
Deep Pan, High-Volume Pump & Cooler
Extra fluid capacity, a high-volume pump, and a dedicated cooler keep temps down through repeated hard passes.
