About TREMEC Manual Transmissions

TREMEC manual transmissions are widely used across OEM and aftermarket automotive applications where precise shifting, durability, torque capacity, and performance are important.

The TREMEC aftermarket lineup covers several distinct manual transmission families. Popular options include the TKX 5-speed, T-5 5-speed, TR-4050 5-speed, Magnum 6-speed, Magnum-F 6-speed, and Magnum-XL 6-speed.

Each transmission serves a different type of application.

The TREMEC TKX is a compact 5-speed rear-wheel-drive transmission designed specifically for aftermarket applications. Its packaging makes it particularly attractive for classic muscle cars, hot rods, and restomod projects where transmission-tunnel clearance can be limited.

The TREMEC Magnum family provides 6-speed performance options for applications requiring greater torque capacity and double-overdrive gearing.

For truck and 4×4 applications, the TR-4050 provides a heavy-duty 5-speed manual transmission platform with synchronized forward gears and provisions for demanding vehicle applications.

Choosing the Right TREMEC Transmission

When selecting a TREMEC manual transmission, begin with the engine, vehicle, expected torque output, available installation space, and intended use.

Important specifications include gear count, gear ratios, torque capacity, input shaft, output spline, bellhousing compatibility, shifter position, overall dimensions, and overdrive ratio.

Torque capacity is particularly important for modified vehicles.

For example, the TREMEC TKX is rated for 600 lb-ft of torque, while the Magnum is rated for 700 lb-ft. These specifications make them suitable for different engine and drivetrain combinations.

Gear ratios also affect how the vehicle behaves. First-gear ratio should complement the rear axle ratio and tire size, while the overdrive ratio influences cruising RPM.

Shifter location deserves consideration in restorations and custom builds. TREMEC designs certain aftermarket transmissions with multiple shifter-position options, providing additional flexibility when fitting a modern gearbox into an older vehicle.

Buyers should also verify clutch, flywheel, bellhousing, pilot bearing, driveshaft, crossmember, speedometer, and transmission-mount requirements before selecting a gearbox.

Available Options

Our TREMEC manual transmission selection may include several configurations for street, performance, restoration, and truck applications.

Depending on current inventory, buyers may find:

• TREMEC TKX 5-speed transmissions
• TREMEC T-5 5-speed transmissions
• TREMEC Magnum 6-speed transmissions
• TREMEC Magnum-F 6-speed transmissions
• TREMEC Magnum-XL 6-speed transmissions
• TREMEC TR-4050 5-speed transmissions
• 5-speed manual transmissions
• 6-speed manual transmissions
• Double-overdrive transmissions
• GM-compatible configurations
• Ford-compatible configurations
• Muscle car transmissions
• Restomod transmission options
• Performance and custom drivetrain gearboxes
• Truck and 4×4 manual transmission applications

Different configurations can be available within the same transmission family.

For example, certain TREMEC transmissions offer different gear-ratio sets or shifter arrangements. Buyers should therefore compare the individual manufacturer part number rather than selecting solely by the TKX or Magnum designation.

Supported Models and Applications

TREMEC manual transmissions support an extensive range of OEM, aftermarket, restoration, performance, and custom applications.

The TKX 5-speed is designed for aftermarket Ford and GM restomod applications and can be particularly useful in classic vehicles where transmission-tunnel clearance is an important consideration.

The Magnum family provides 6-speed options for muscle cars, hot rods, pro-touring vehicles, road-performance builds, and modern engine swaps.

The Magnum-F is specifically designed around GM F-body applications and can support compatible Camaro and Firebird configurations, including certain LS-powered applications.

Other TREMEC transmissions have been associated with applications involving Ford Mustang, Chevrolet Camaro, Pontiac Firebird, Corvette, performance Ford and GM vehicles, classic muscle cars, trucks, 4x4s, and custom builds.

Exact compatibility depends on the individual transmission and drivetrain.

Engine family, bellhousing, clutch, input shaft, output spline, driveshaft, crossmember, transmission tunnel, shifter location, rear gearing, and other components should all be considered.
