Description

Adding a modern 5-speed overdrive to your '64.5-'65 Mustang shouldn't require cutting the tunnel or scrapping your entire clutch system. This complete T5 conversion package solves that problem by using an adapter plate behind your original 5-bolt bellhousing, letting you retain the factory clutch linkage, fork, and Z-bar while gaining the benefits of a true overdrive transmission.

The heart of this package is TREMEC's Super Duty T5 5-speed, the smallest and lightest transmission in their lineup at just 75 lbs dry. Don't let the compact size fool you--this gearbox safely handles 330 ft-lb of torque and is suitable for street cars making up to 450 hp on DOT-approved tires. The 2.95:1 first gear delivers strong launches, while the deep 0.63:1 overdrive fifth gear significantly drops highway RPMs, reducing engine stress, lowering temperatures, and improving fuel economy on those long cruises.

The included offset shifter slides directly into your stock shifter hole and positions the knob exactly where Ford intended, maintaining the car's original character. MDL's guided package selection walks you through choosing the right flywheel balance, clutch type, speedometer gearing, and slip yoke for your specific engine and rear axle combination--every component engineered to work together for a seamless installation. The T5z specification is specifically designed for retrofitting 4-speed or automatic transmissions in classic cars and hot rods with small-block engines.

Requires 2.75 quarts of Dexron III ATF for fill. At any point during your build, MDL's technical support team is available to help you make the right part selection for your project and budget.
