Description

Converting your '74-'78 Mustang II to a modern 5-speed overdrive means dealing with the platform's unique bellhousing clocking, tight transmission tunnel, and factory shifter positioning. This complete TREMEC T5 package solves all three challenges with application-specific components engineered for the Mustang II chassis.

The TREMEC T5 is the most compact transmission in the TREMEC lineup, weighing just 75 lbs dry -- ideal for the Mustang II's space constraints. Its 2.95:1 first gear delivers strong acceleration off the line, while the 0.63:1 overdrive fifth reduces cruising RPM for better fuel economy and quieter highway operation. The T5 safely handles up to 330 ft-lbs of torque [VERIFY: TREMEC official spec shows 300 lb-ft], making it well-suited for small block Ford builds on DOT-approved tires. The included 2" offset shifter keeps the lever in the factory location, so you get modern overdrive performance without modifying your interior.

The QuickTime bellhousing is purpose-built for the Mustang II application, with the clutch fork and starter clocked to OEM positions for direct fitment. Unlike rolled or stamped bellhousings, the QuickTime cone is spun from high-grade steel that work-hardens to over 80,000 PSI -- more than twice the strength of other steel bellhousings. This manufacturing process delivers the most dimensionally accurate bellhousing available, ensuring proper engine-to-transmission alignment throughout the entire RPM range. That precision eliminates accelerated drivetrain wear caused by bellhousing flex. The design accommodates 157-tooth flywheels and 10.4" metric-pattern clutches for strong power handling.

MDL's guided package builder walks you through selecting the right speedometer gear, shift knob, crossmember, driveshaft yoke, and fluid for your specific build. Every component is selected for compatibility with your Mustang II and small block Ford combination.
