Description

The factory SROD 4-speed in '79-'81 Mustangs was built for economy, not performance. Rated at roughly 200 ft-lb of torque and long out of production support, the SROD becomes the weak link the moment you start building power - or simply need a reliable daily driver. This MDL T5 conversion package delivers a complete, properly engineered solution that transforms your early Fox Body into a modern-driving machine with genuine performance capability.

At the heart of this package sits the TREMEC Super-Duty T5 5-speed with 2.95:1 first gear and 0.63:1 overdrive. This isn't a recycled junkyard unit - it's a brand-new aftermarket transmission rated at 330 ft-lb of torque, making it suitable for street-driven V8s up to 450 hp on DOT-approved tires. At just 75 lbs. dry, the T5 is TREMEC's most compact offering, fitting the tight Fox body tunnel where larger transmissions cannot. The deep overdrive substantially drops cruising RPMs, improving fuel economy and reducing drivetrain noise at highway speeds.

This package was engineered specifically for the '79-'81 Mustang platform. The included offset shifter positions perfectly in the factory SROD location, eliminating tunnel cutting and console modifications. Your existing clutch cable, pedal assembly, and fork are retained - this is a cable-clutch conversion that doesn't require hydraulic system upgrades. The dedicated crossmember and transmission mount ensure proper drivetrain alignment and solid mounting.

MDL's package configurator walks you through every component selection: bellhousing options for 6-bolt small block applications, flywheel choices from steel to lightweight aluminum in multiple balance configurations, clutch kits scaled to your power level, speedometer gear or electronic sensor options, and driveshaft yokes in 1310, 1330, and 1350 series. Whether you're running a stock 302 or a built small block, this system delivers the right combination for your build.
