Description

Swapping your '69-'70 Mustang or Cougar from automatic to a proper five-speed transforms the entire driving experience - lower cruise RPM, better fuel economy, and the direct mechanical connection that makes classic muscle cars worth driving. This complete TREMEC T5 conversion package eliminates the guesswork by bundling every component you need for a full auto-to-manual swap behind a Ford small-block engine.

The TREMEC T5 is the ideal transmission for first-gen Mustang and Cougar builds where space is tight and torque stays below 330 lb-ft on street tires. At just 75 lbs dry, it's TREMEC's most compact offering - perfect for tight engine bays where every inch matters. The 2.95:1 first gear delivers strong take-off performance, while the 0.63:1 overdrive drops highway RPM significantly, reducing engine temperatures and in-cabin noise while stretching fuel economy.

MDL's guided package selector walks you through every choice - bellhousing material (aluminum or steel), flywheel configuration (nodular iron, steel, or aluminum with 0, 28, or 50 oz balance options), clutch combinations for your power level, and cable or hydraulic clutch actuation. The offset shifter design positions the stick precisely in the OEM shifter hole, maintaining factory appearance without cutting or modifying your transmission tunnel.

Every package includes a vehicle-specific crossmember and transmission mount engineered for proper driveline angles, plus speedometer cable, driven gear, and reverse light harness to complete the swap. Like all TREMEC aftermarket transmissions, the T5 is built from 100% brand-new OEM-quality components and requires 2.75 quarts of Dexron III ATF. Lifetime technical support comes standard with every complete MDL conversion package.
