Description

This customizable T5 conversion package eliminates the performance limitations of factory three and four-speed manual transmissions in '65-'66 Mustangs. The TREMEC T5 safely handles 330 ft-lb of torque and is suitable for 450 hp streetcars on DOT-approved tires, making it the ideal upgrade for small block Ford builds where space is at a premium and drivability matters.

The smallest and lightest of the TREMEC transmission line, this T5 installs without cutting or major modifications by utilizing your existing six-bolt bellhousing and an adapter plate. The 2.95:1 first gear provides strong take-off performance, while the compact design makes it ideal for tight engine bays. The custom offset shifter positions correctly in the stock Mustang console opening, preserving interior originality while delivering modern five-speed operation.

Unlike generic kits, this package offers complete component selection flexibility. Choose from multiple flywheel options (steel or aluminum), clutch packages for different torque levels, shift lever configurations, crossmember solutions, and driveline components. MDL's guided package selection walks you through each choice, and our team is available to provide concierge service to help you select the right parts for your project and budget.

The single overdrive reduces RPMs for improved fuel economy, lower engine temperatures, and quieter highway cruising. Compatible with 1965-1966 Ford Mustangs equipped with six-bolt small block engines. The package preserves your stock clutch linkage and related components while adding the benefits of modern five-speed performance.
