AX15 5 Speed Manual Transmission

AX15 5-Speed Overdrive Transmission - 1966-77 Ford Bronco (Transmission Only)

Upgrade Your Bronco with Modern Transmission

Transform your classic 66-77 Ford Bronco with our new AX15 5-speed overdrive transmission, engineered to deliver modern driving performance while maintaining compatibility with your Bronco’s drivetrain. This modern manual transmission upgrade enhances drivability, offering smoother shifts, improved gearing, and greater overall efficiency.

Superior Performance and Efficiency

The AX15 transmission is well known for its durability and excellent performance characteristics. It features a 1st gear ratio of 3.83 for strong low-end torque and a 21 percent overdrive in 5th gear, allowing for reduced RPM at cruising speeds. This results in improved fuel economy and a quieter, more comfortable highway driving experience.

Customization and Compatibility

This transmission upgrade includes a custom clutch disc and pilot bushing designed specifically for the AX15 Early Bronco swap, ensuring proper fitment and optimal performance. For Broncos equipped with a 10-inch clutch and flywheel setup, an upgrade to an 11-inch clutch and flywheel kit is required to ensure compatibility.

NOTE: If your Bronco currently has a 10-inch clutch and flywheel, you will need to upgrade to the 11-inch clutch and flywheel kit, available here.
