Description

Converting your '69-'70 Mustang or Cougar from automatic to a proper manual transmission transforms the driving experience. This complete MDL conversion package centers around the TREMEC T5z Super Duty 5-speed, the smallest and lightest in the TREMEC lineup, yet fully capable of handling 330 ft-lb of torque behind small-block Ford engines producing up to 375 horsepower on street tires. The T5z is the ideal transmission for retrofitting classic cars and hotrods where compact dimensions matter and outright brutality isn't the goal.

The engineering behind this package addresses the specific challenges of first-gen Mustang conversions. The T5's compact design fits where larger transmissions simply won't, sliding into the original tunnel without modifications. The offset shifter position drops perfectly into the factory automatic console opening, preserving the interior's stock appearance. The 2.95:1 first gear provides strong take-off performance, stepping through close ratios that keep your small-block in its powerband, then dropping into that fuel-saving 0.63:1 overdrive for relaxed highway cruising with lower RPMs, reduced engine temperatures, and a much quieter in-cabin feel.

Every component in this package has been selected and tested for compatibility with '69-'70 Mustang and Cougar applications running small-block Ford 6-bolt engines. From aluminum or steel bellhousing options to clutch pedal assemblies designed specifically for automatic-to-manual conversions, this isn't a generic kit. Choose between mechanical clutch cable actuation or a hydraulic master/slave cylinder setup based on your preferences and driving style. Multiple flywheel weights, clutch configurations, and shift lever styles let you tailor the package to your specific build.

MDL's guided package configurator walks you through each decision point based on your engine, power level, and driving goals. Our concierge service is available if you need help selecting the correct parts for your project and budget. Whether you're building a weekend cruiser or a spirited street machine, this T5 package delivers the reliability, smooth shifting, and driving enjoyment that makes every mile memorable.
