Description

Give your Ford Y-block-powered classic the overdrive it never had. This comprehensive T-5 conversion package transforms a tired three-speed manual into a smooth-shifting five-speed, delivering modern drivability and highway manners while preserving the classic character of Ford's first overhead-valve V8. The Ford Y-block (1954-1964) was a landmark engine that powered Thunderbirds, Fairlanes, and countless customs - and it deserves a transmission that lets you actually enjoy cruising instead of winding out at highway speeds.

The TREMEC T-5 is the smallest and lightest transmission in the TREMEC lineup, making it ideal for tight engine bays and weight-conscious builds. The 2.95:1 first gear delivers strong launches, while the 0.63:1 overdrive fifth gear drops engine RPM significantly for quieter, cooler highway cruising. Gear ratios of 2.95, 1.94, 1.34, 1.00, and 0.63 give you the spread you need for spirited driving and relaxed touring. With a 300 lb-ft torque capacity, the T-5 safely handles the moderate power levels typical of street-driven Y-block engines.

Every component in this package has been selected specifically for Y-block conversions. The adapter ensures proper bellhousing-to-transmission alignment, while the complete hardware kit provides all necessary mounting fasteners. Our guided package selection walks you through optional components - shift knobs, speedometer gears, transmission mounts, and slip yokes - so you can customize the package for your specific vehicle and driveline configuration.

MDL has decades of experience in TREMEC conversions, ensuring you get the right parts the first time. If you need help selecting components or have questions about fitment, our technical team is available to provide personalized assistance for your Y-block T-5 project.
