Description

Tremec T-56 Magnum XL Manual Transmissions TUKT12019 – Product Overview

The Tremec T-56 Magnum XL Manual Transmissions TUKT12019 is a high-performance 6-speed manual transmission from Tremec. It is part of the Tremec T-56 Magnum XL Manual Transmissions product line and is supplied as a new, non-remanufactured transmission assembly sold individually.

This transmission is identified by Manufacturer’s Part Number TUKT12019 and Summit Racing Part Number REM-TUKT12019. These identifiers help buyers, installers, and parts departments confirm the correct unit before ordering.

The Magnum XL platform begins with an extended length rear extension housing. This design is intended for late model performance applications that use factory semi-remote shifters and need a more direct, rigid, and precise gear-change feel.

Instead of the loose or rubbery feel often associated with some semi-remote shifter designs, the Tremec T-56 Magnum XL TUKT12019 gives owners a direct-shift Magnum XL layout with crisp, low-effort engagement.

This model uses a 6-speed gear layout with 2.66 first gear, 1.00 fourth gear, 0.74 fifth gear, and 0.50 sixth gear. The fifth and sixth gears provide double-overdrive capability for performance vehicles that also need more relaxed cruising behavior.

The transmission uses a 1.125-inch input shaft diameter with 26 input splines. It also uses a 31-spline output shaft. These details are important for selecting the correct clutch disc, output yoke, driveshaft setup, and supporting components.

This transmission includes the shifter, crossmember, and scatter shield, but it does not include a bellhousing and does not include a yoke.

Fitment and Application Details

The Tremec T-56 Magnum XL Manual Transmissions TUKT12019 is intended for late model performance applications that require an extended rear extension housing and direct-shift layout.

This transmission is especially useful where the vehicle’s original factory semi-remote shifter layout creates a less precise gear-change feel. The Magnum XL design replaces that feel with a stronger direct-shift connection.

Fitment should be confirmed before ordering by checking vehicle platform, engine, bellhousing requirements, clutch disc spline count, flywheel, pilot bearing, clutch release system, transmission mount, crossmember fitment, driveshaft length, output yoke, tunnel clearance, and shifter position.

Because this transmission uses a 26-spline input shaft, a compatible 26-spline clutch disc is required. Because it uses a 31-spline output shaft, the correct output yoke must be selected separately.

The bellhousing is not included, so buyers should choose the correct bellhousing for the engine, clutch system, and application. The yoke is not included, so the slip or output connection must be verified before installation.

The product includes a crossmember and scatter shield, but buyers should still confirm that the included components match the intended application and installation layout.

For buyers browsing the manual transmissions category, this transmission fits naturally with related drivetrain parts such as clutch kits, flywheels, pilot bearings, bellhousings, yokes, driveshaft parts, transmission mounts, fluids, wiring components, and installation hardware.

Build Quality and Reliability

The Tremec T-56 Magnum XL Manual Transmissions TUKT12019 is built with Tremec’s Magnum-level strength and performance-focused construction.

The transmission is rated for 700 lb-ft of torque capacity, giving it serious power-handling capability when installed with compatible clutch, driveline, mount, and supporting components.

The Magnum XL platform also uses race-proven synchronizer technology. This supports crisp, low-effort shifts and helps the transmission handle demanding performance use with clean engagement.

The supplied product details state that the Tremec T-56 Magnum XL is equipped to deal with all but the highest revving engines, with rpm capacity nearing 8,000 rpm straight out of the box.

The transmission uses an aluminum case, providing a strong and practical housing for performance use while keeping unnecessary weight lower than heavier case materials.

The extended length rear extension housing is a key part of the Magnum XL design. It supports the direct-shift layout needed for late model applications that originally relied on factory semi-remote shifter arrangements.

The included shifter gives buyers a more complete starting point for installation planning, while the included crossmember and scatter shield add further value for compatible applications.

What Makes This Transmission a Strong Choice

The Tremec T-56 Magnum XL Manual Transmissions TUKT12019 is a strong choice for buyers who need a high-capacity 6-speed transmission with direct-shift performance and double-overdrive cruising.

One of its biggest strengths is the 700 lb-ft torque capacity. This makes it suitable for demanding performance applications when the complete drivetrain is properly matched.

Another key advantage is the direct-shift Magnum XL layout. This helps replace the less connected feel of some factory semi-remote shifters with a more rigid and precise manual shifting experience.

The 2.66 first gear provides strong performance engagement, while the 0.74 fifth gear and 0.50 sixth gear offer double-overdrive capability. The 0.50 sixth gear is especially valuable for buyers who want reduced engine rpm during highway cruising when the rear axle ratio and tire size are properly matched.

The included shifter, crossmember, and scatter shield also make this transmission more complete than a transmission-only setup. Buyers should still confirm application compatibility before ordering.

The Tremec T-56 Magnum XL TUKT12019 is also a strong fit for drivers who want crisp, low-effort gear changes, modern Tremec construction, and high torque capacity in a late model performance transmission layout.

Ideal Buyers and Use Cases

The Tremec T-56 Magnum XL Manual Transmissions TUKT12019 is best for late model performance vehicle owners, drivetrain installers, performance shops, mechanics, and builders who need a strong 6-speed manual transmission with direct-shift operation.

It is suitable for buyers upgrading from a factory semi-remote shifter layout where the original shift feel is loose, rubbery, or less precise than desired.

This transmission is also useful for high-performance street builds, pro-touring vehicles, track-focused applications, and custom drivetrain projects that require 700 lb-ft torque capacity, double-overdrive gearing, and Tremec Magnum XL fitment.

It is not a complete universal installation kit. The bellhousing is not included, and the yoke is not included. Buyers should confirm those parts before ordering.

The best buyer for this product is someone who has already confirmed bellhousing compatibility, clutch spline requirements, output yoke needs, driveshaft length, tunnel clearance, transmission mount fitment, crossmember compatibility, and shifter position.

Technical Specifications

Ordering Support and Fitment Guidance

Before ordering the Tremec T-56 Magnum XL Manual Transmissions TUKT12019, buyers should confirm the full drivetrain setup for the intended vehicle.

Important details include vehicle platform, engine, bellhousing selection, clutch disc spline count, flywheel, pilot bearing, clutch release system, output yoke, driveshaft length, transmission mount, crossmember fitment, tunnel clearance, shifter position, fluid requirements, and installation hardware.

This transmission uses a 26-spline input shaft, so the clutch disc must match that spline count. It also uses a 31-spline output shaft, so the correct yoke must be selected separately.

The shifter is included, along with the crossmember and scatter shield. However, the bellhousing is not included, and the yoke is not included.

For a complete drivetrain installation, buyers may also need clutch components, flywheel, pilot bearing, release bearing, compatible bellhousing, output yoke, driveshaft parts, fluid, wiring components, and vehicle-specific hardware.

The Tremec T-56 Magnum XL Manual Transmissions TUKT12019 is built for buyers who want high torque capacity, direct-shift performance, deep double-overdrive gearing, and crisp Tremec Magnum XL shift quality.
