Description

Give your 1940-1947 Ford Truck the overdrive it deserves while keeping the mechanical clutch linkage Ford engineers designed for these heavy-duty chassis. The 59A flathead features an integral cast-in bellhousing with a horizontally-mounted clevis cross shaft for clutch actuation - and this complete T5 conversion package is engineered specifically to work with that factory setup. No hydraulic conversion, no cutting the firewall, just a modern five-speed that bolts up and shifts like it belongs there.

The heart of this package is the TREMEC Super Duty T5z, safely handling 330 ft-lb of torque with gear ratios optimized for V8 applications. The 2.95:1 first gear provides the strong launch these trucks need, whether you're pulling away from a stop sign or getting a loaded bed rolling. The 0.63:1 overdrive drops highway RPMs dramatically, reducing engine temperatures and promoting longer engine life while making those long cruises far more enjoyable. At just 75 lbs. dry, this is the smallest and lightest TREMEC transmission - it fits where others cannot, slipping into factory tunnels with minimal modification.

MDL's adapter mates the T5 to your 59A's integral bellhousing while preserving the clevis cross shaft mechanism. This truck-specific design uses the original clutch actuation geometry rather than forcing a round-shaft or hydraulic conversion. The front-shift tail housing positions the shifter forward for natural reach from the bench seat. Choose from MDL's selection of 10-inch long pattern clutches, billet flywheels, and custom shifters - every component selected to work together as a complete drivetrain solution.

The guided package builder walks you through each selection: transmission, adapter, flywheel, clutch, shifter style, shift boot, speedometer components, and output yoke. Every part is engineered for 59A flathead applications. If you need help navigating the options, MDL's tech support team knows these trucks inside and out. Compatible with 1940-1947 Ford Trucks equipped with the 59A flathead engine and clevis-style clutch cross shaft. Made in the USA.
