WPD 10L80 Competition Transmission

1,000+ HP Rated

The WPD 10L80 Competition Transmission is built for enthusiasts who refuse to let the transmission become the limiting factor. Designed for high-horsepower street cars, drag racing, roll racing, and boosted applications, this transmission combines proven OEM improvements with extensive performance upgrades to reliably handle 1,000+ horsepower while maintaining excellent drivability.

Every transmission is hand-built using carefully selected components, precision clearances, and proven hydraulic modifications developed through extensive testing. Rather than simply increasing clutch count, we’ve focused on improving lubrication, hydraulic efficiency, heat management, and clutch apply to create a transmission that performs consistently under repeated abuse.

Whether you’re building a twin turbo Camaro, supercharged Silverado, boosted Tahoe, or another GM platform equipped with the 10L80, this transmission is engineered to deliver the confidence you need every time you put your foot down.

Engineered for High Power

The factory 10L80 is an impressive transmission, but once horsepower and torque begin climbing, heat, lubrication, and hydraulic control become critical.

Our Competition Build addresses these weak points by improving clutch holding capacity, increasing lubrication throughout the transmission, reducing heat, and reinforcing the components that see the greatest stress under high horsepower. The result is a transmission capable of handling aggressive launches, repeated pulls, and competition use while maintaining smooth, predictable operation.

Built Around Your Combination

No two performance builds are identical.

Every WPD 10L80 Competition Transmission is configured around your vehicle, horsepower goals, turbocharger or supercharger setup, converter requirements, tire size, and intended use. This allows us to provide the proper stall speed, hydraulic calibration, and overall setup for maximum performance and long-term reliability.

When you’re investing in a high-performance GM build, your transmission should be engineered to match the rest of your combination—not become the next weak link.
