Description

Converting your '69-'70 Mustang or Cougar from automatic to a five-speed manual transforms the driving experience - and this complete TREMEC T5 package eliminates the guesswork. Designed specifically for Ford small-block applications in first-generation Mustangs and Cougars, every component has been selected and tested for seamless compatibility. The T5z (Super Duty) transmission delivers smooth shifting, easy operation, and a deep overdrive that makes highway cruising genuinely enjoyable - all in the most compact, lightweight package TREMEC offers.

The T5 is the smoothest-shifting and most reliable manual transmission dollar-for-dollar, pound-for-pound. At just 75 lbs dry, it installs without cutting or modification - the offset shifter design drops directly into the OEM shifter hole to maintain the factory shifter position. A 2.95:1 first gear provides strong launches, while the fuel-saving 0.63:1 overdrive drops rpm significantly at highway speeds, reducing engine temperatures and in-car noise while improving fuel economy.

This Super Duty T5 (Z-spec) is built with stronger internals than the stock '83-'93 Mustang T5s: a steel front bearing retainer, Cobra-style pocket bearing, and carbon fiber synchro rings on gears 1-4. World Class construction means tapered carrier bearings and needle bearings under the main gears for reduced drag and improved durability. Like all TREMEC aftermarket transmissions, it's built from 100% brand-new OEM-quality components.

MDL's guided package selection walks you through choosing the right bellhousing, flywheel, clutch, hydraulic system, crossmember, and accessories for your specific application. If you're ever uncertain, MDL's concierge service can help you select the correct parts for your project and budget - backed by lifetime technical support.
