10R80 Transmission Swaps: Bringing Modern Performance to Classic Cars

The Ford 10R80 transmission has quickly become one of the most popular modern swaps for performance builds — from Foxbody Mustangs to restomod Broncos and classic F-100s. Its fast, adaptive shifting and robust torque capacity make it the perfect match for high-output Coyote and Windsor-based engines. But making that work in a vintage car takes more than just bolting it in — and that’s where Monster Transmission steps in.

From a Dream to SEMA — Our 10R80 Partnership with Constance Nunes

When Constance Nunes — builder, model, and star of Netflix’s Car Masters: Rust to Riches — set out to build a one-of-a-kind classic Mustang for SEMA 2025, she needed a drivetrain that could handle modern power and daily driveability.

That’s where Monster Transmission came in. We partnered with Constance and the her team to provide a complete 10R80 conversion package for her SEMA build — a stunning Mustang powered by a 351 Windsor stroked to 408 cubic inches.

The car features our Monster 10R80 transmission paired with a Quick 10 transmission controller and a complete adapter kit — designed so the small block Ford bolts up flawlessly to the modern 10-speed automatic. The result? Lightning-fast shifts, rock-solid reliability, and seamless drivability in a classic platform.

Why the 10R80 Is the Future of Swaps

The 10R80 (jointly developed by Ford and GM) is more than just another overdrive transmission. It’s engineered for both performance and efficiency, using adaptive learning to optimize shifts for driving style and load. In performance builds, it provides:

• 10 close-ratio gears for instant response and power delivery
• Low first gear (4.70:1) for incredible launch potential
• Lockup torque converter for highway efficiency and cooling
• Compact case design that fits in many classic chassis with minimal modification
• High torque capacity — perfect for built small-blocks and Coyotes alike
