Description

Converting your '65-'66 Mustang from automatic to manual delivers the control and engagement that makes these early pony cars truly come alive. This customizable conversion package pairs the TREMEC TKX 5-speed transmission with Ford small block bellhousings, hydraulic clutch systems, and all supporting components - letting you build a complete drivetrain conversion matched to your engine, driving style, and budget.

The TREMEC TKX represents the latest evolution in aftermarket 5-speed transmissions, purpose-built for restomod applications. With 600 lb-ft of torque capacity and shifts rated at 7,500 RPM, the TKX handles serious power upgrades. Superior shift quality comes from multi-cone synchronizers and hybrid sintered bronze/carbon synchronizer rings, while a ribbed 3-piece aluminum housing provides structural stiffness and optimized NVH performance. Oversized gear widths and caged needle bearings in all positions ensure long-term durability. Choose wide ratio (3.27, 1.98, 1.34, 1.00, 0.72) for street performance or close ratio (2.87, 1.89, 1.28, 1.00, with 0.68 or 0.81 fifth gear options) for track-oriented builds.

MDL's guided package configurator walks you through every component choice. Select from Ford small block aluminum or steel bellhousings, flywheels in cast, billet steel, or aluminum at multiple weights, single-disc or twin-disc clutch systems, complete hydraulic master and external slave cylinder setups, custom shifters, shift knobs and boots, speedometer solutions (mechanical or electronic), transmission mounts, driveshaft yokes, and all necessary hardware. Every component is selected for compatibility with your '65-'66 Mustang application.

Installation note: Proper TKX installation in 1964.5-66 Mustangs requires moving the floor support back 2.75 inches. For builds under 450 horsepower where this modification is not desired, consider MDL's Super Duty T5 packages as an alternative. Contact MDL's technical team for concierge assistance in selecting the right components for your project.
