Description

Converting a 1932-1939 Ford Flathead to five-speed overdrive means solving a fundamental engineering challenge: replacing the integral bellhousing transmission with modern components while preserving the original clutch release mechanism. This complete TREMEC T5 package delivers exactly that solution for 59A engine blocks equipped with the round clutch cross shaft configuration found in Ford passenger cars and 122-inch wheelbase commercial trucks of this era.

The TREMEC T5 Super Duty handles 330 ft-lb of torque while weighing just 75 lbs dry - making it ideal for space-constrained Flathead installations where larger transmissions simply won't fit. Gear ratios of 2.95/1.94/1.34/1.00/0.63 provide strong acceleration off the line and relaxed highway cruising. As the smallest of the TREMEC five-speeds, the T5 fits into most factory tunnels or below the floor without major modifications. Modern Driveline's front-shifted T5 moves the shifter forward to match OEM transmission positioning, delivering comfortable shifting that feels natural in your '30s Ford.

The MDL-engineered adapter maintains the original horizontal round cross shaft design that mounts across the lower bellhousing with vertical clutch fork operation - preserving the mechanical advantage Ford designed into these early V8s. Modern Driveline developed custom diaphragm clutches and Flathead-specific flywheels to ensure proper clutch release with modern transmission input shafts. The 10-inch long pattern clutch design fits 59A engines with the 3-inch intermediate ring, and all clutches are handmade in-house and tested for proper release rates.

This guided package system walks you through selecting the right transmission, adapter, flywheel, clutch set, shifter configuration, speedometer components, and driveline hardware for your specific build. Requires 2.75 quarts of ATF Dexron III. A cross member must be fabricated to support the transmission. Engineered and assembled in Caldwell, Idaho.
