Description

Converting your '79-'81 Fox Body Mustang or Capri from automatic to manual delivers the driving experience these cars were meant to have - and this complete T5 package eliminates the guesswork. The TREMEC Super-Duty T5 is the perfect 5-speed solution for moderate horsepower builds where space and weight matter, offering 330 ft-lb of torque capacity suitable for streetcars up to 450 hp on DOT-approved tires while weighing just 75 lbs dry.

This package was engineered specifically for early Fox Body automatic-to-manual conversions, addressing every detail from bellhousing selection to shifter positioning. The fuel-saving 0.63:1 overdrive drops highway RPMs for improved fuel economy, reduced engine temps, and a quieter in-car experience, while the 2.95 first gear provides strong take-off performance. The offset shifter design slides into your OEM shifter hole with the correct boot, maintaining factory appearance and ergonomics - no console modifications required.

MDL's guided selection process walks you through every component choice, from bellhousing material (aluminum or steel) to flywheel weight and clutch capacity. Choose from SFI-approved flywheels, ARP fasteners, and matched clutch sets to build the exact drivetrain your project demands. Each component is selected for compatibility and performance, ensuring your conversion works correctly the first time. Our technical team provides concierge-level support to match components to your specific engine, power goals, and budget requirements.

The T5 has earned its reputation as one of the most reliable and versatile 5-speeds ever produced. Originally factory equipment in 5.0L Mustangs, it remains the go-to choice for classic car conversions thanks to its compact dimensions, smooth shifting, and proven durability. Whether you're building a weekend cruiser or a spirited street machine, this package delivers everything you need for a complete, professional-quality swap.
