TREMEC T-56 6-Speed Manual Transmission

T-56 transmission built for compatible muscle cars, restomods, street cars, performance builds, and custom drivetrain projects. This TREMEC T-56 is a 6-speed manual transmission with a longitudinal layout and dual overdrive gears.

The six-speed design gives your build more gearing for acceleration and cruising. Fifth and sixth gears provide overdrive ratios that can help reduce engine RPM during highway driving.

The transmission uses an aluminum case and steel gearsets with a multi-cone synchronizer configuration. As with any manual transmission, the correct application depends on the engine, bellhousing, clutch, driveshaft, shifter position, and other drivetrain components.

T56 6-Speed Manual for Performance Builds

This T56 6-speed manual transmission gives performance builders the control and engagement of a manual gearbox. Six forward speeds also provide more flexibility than traditional four- and five-speed manual transmissions.

The dual-overdrive layout makes the T-56 suitable for builds that need both strong acceleration and comfortable highway cruising. It can be a good fit for compatible muscle cars, restomods, street cars, and engine swap projects.

Choosing the Right T56 Transmission

A TREMEC T56 transmission is not a universal fit for every vehicle. T-56 configurations can vary by application, so confirm the exact specifications before ordering.

Check the engine and bellhousing pattern, clutch and flywheel, transmission crossmember, driveshaft length, shifter location, differential gearing, and vehicle electronics. These details can affect whether the transmission is compatible with your build.

T-56 Transmission Fitment

When comparing a T56 transmission for sale, look beyond the six-speed designation. The input shaft, output configuration, gearing, shifter position, and mounting requirements should match your engine and chassis.

If you’re planning an LS swap, muscle car build, restomod, or other performance project, verify the complete drivetrain combination before purchase. This helps ensure the transmission works with the engine and supporting components you plan to use.

TREMEC T-56 Manual Transmission
