RSA Race Solutions Stage 3 10R80 Transmission Build

Built for 1300+ WHP Extreme Performance Applications

The RSA Race Solutions Stage 3 10R80 Transmission Build is designed for serious high-horsepower builds exceeding 1300 wheel horsepower. Engineered for extreme power, aggressive driving, and race-level abuse, this package delivers maximum holding capacity, durability, and shift consistency for the most demanding applications.

Whether you’re running a fully built engine, large turbo setup, or pushing your platform to the limits at the track, the Stage 3 build ensures your 10R80 transmission can keep up.

Maximum Clutch Capacity for Extreme Torque

The Stage 3 build features a further increased clutch count, providing the highest level of holding power available in RSA’s lineup. Combined with high-performance GPZ clutches and friction fibers, this setup is built to withstand extreme torque loads, high boost levels, and repeated hard launches without slip or failure.

RSA Custom Valve Body for Race-Level Shifting

At this power level, precise fluid control is critical. The included RSA custom valve body is engineered to deliver fast, firm, and consistent shifts, ensuring maximum power transfer and reducing internal wear. This upgrade enhances both performance and reliability under extreme conditions.

Complete Tear-Down & Blueprinted Assembly

Each Stage 3 transmission undergoes a complete tear-down, inspection, and cleaning process before assembly. New seals and a transmission filter are installed to ensure optimal fluid control and long-term durability. Every build is carefully assembled to meet RSA’s strict performance standards.

What’s Included

  • Increased clutch count for maximum torque capacity
  • GPZ upgraded clutch packs and friction fibers
  • RSA custom valve body
  • New seal kit
  • New transmission filter
  • Complete tear-down, inspection, and cleaning

Key Features

  • Designed for 1300+ WHP applications

  • GPZ clutches for superior heat resistance and durability
  • RSA custom valve body for precise, high-performance shifting
  • Improved reliability under race-level conditions
  • Ideal for drag racing, high-boost, and extreme builds

Why Choose Stage 3?

At extreme horsepower levels, the factory 10R80 transmission is prone to clutch failure, overheating, and inconsistent shifting. The RSA Stage 3 Build eliminates these weaknesses by reinforcing critical components and maximizing clutch capacity—giving you the confidence to push your build to its limits.

Important Notes

  • Additional parts or upgrades may be required depending on transmission condition after teardown which may result in additional parts needed.
  • Final cost may vary if additional components are needed during inspection
  • Shipping both ways will need to be arranged and payed for by the customer.  Feel free to call for more details or questions.
  • Professional installation and tuning recommended for best results
