Description

Swapping a Ford Modular engine into your first-gen Mustang transforms the car - but leaving it strapped to an automatic transmission leaves half the experience on the table. This complete TREMEC T5 conversion package delivers everything you need to add a modern 5-speed manual to your '69-'70 Mustang with a 4.6L or 5.0L Modular powerplant, whether you're converting from an existing automatic or building from scratch with all-new components.

The TREMEC T5z is the smallest and lightest transmission in the TREMEC lineup, making it an ideal choice for first-gen Mustangs where tunnel clearance and weight distribution matter. At just 75 pounds dry, it installs without modifications while safely handling 330 ft-lb of torque - plenty of margin for a built Modular street engine up to 450 hp. The 2.95:1 first gear provides strong launches without the excessive gear multiplication that makes taller first gears unusable on the street, while the deep 0.63:1 overdrive transforms highway cruising by dropping engine speed, reducing operating temperatures, and delivering real-world fuel economy improvements.

MDL has engineered this package to eliminate the guesswork of sourcing individual components. The guided package selection walks you through every decision point - bellhousing, clutch system, hydraulics, flywheel, shifter components, and crossmember - ensuring proper fitment and compatibility. The offset shifter drops directly into the OEM location, maintaining factory appearance while delivering the tactile feedback of a modern 5-speed. Hydraulic clutch options provide consistent pedal effort and self-adjusting operation, leaving cable-actuated compromises in the past.

Every component in this package has been selected and tested by MDL's conversion specialists for this specific application. If you need guidance on matching components to your build goals and budget, MDL's tech team offers concierge support to help you configure the right package.
