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 belongs to the Tremec T-56 Magnum XL Manual Transmissions product line and is supplied as a new, non-remanufactured transmission sold individually.
This transmission is identified by Manufacturer’s Part Number TUKT12019 and Summit Racing Part Number REM-TUKT12019. These identifiers help buyers, mechanics, installers, and parts departments confirm the exact transmission before ordering.
The Magnum XL platform begins with an extended length rear extension housing. This design is intended for late model performance applications that originally use factory semi-remote shifter layouts.
By using a more rigid direct-shift design, the Magnum XL helps replace the loose or rubbery gear-change feel often associated with some semi-remote shifter setups. The result is a more connected manual driving experience with crisp, low-effort shifts.
This model uses a 6-speed gear layout with 2.66 first gear, 1.78 second gear, 1.30 third 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 practical cruising behavior.
The Tremec T-56 Magnum XL Manual Transmissions TUKT12019 includes a shifter, crossmember, and scatter shield. It does not include a bellhousing and does not include a yoke, so buyers should confirm the required supporting components before ordering.
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 product is especially useful where the original factory semi-remote shifter design creates a less precise gear-change feel. The Magnum XL gives buyers a more rigid direct-shift connection for improved manual control.
Fitment should be confirmed before purchase by checking the 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 1.125-inch 26-spline input shaft, it requires a compatible 26-spline clutch disc. Because it uses a 31-spline output shaft, the correct output yoke must be selected separately.
The bellhousing is not included, so buyers must choose the correct bellhousing for the engine, clutch setup, and intended application. The yoke is not included, so the driveline connection must also be verified before installation.
The included crossmember and scatter shield add value, but buyers should still confirm whether these components match the intended vehicle and installation layout.
For a complete drivetrain setup, buyers may also need a clutch kit, flywheel, pilot bearing, release bearing, compatible bellhousing, output yoke, driveshaft parts, fluid, wiring components, transmission mount hardware, and vehicle-specific installation parts.
Build Quality and Reliability
The Tremec T-56 Magnum XL Manual Transmissions TUKT12019 is built around Tremec’s proven Magnum-level performance design. It is engineered for drivers who need high torque capacity, clean shift engagement, and dependable strength in a demanding manual transmission setup.
The transmission is rated for 700 lb-ft of torque capacity, giving it serious power-handling ability when installed with compatible clutch, driveline, mounting, 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 precise gear 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, which provides a strong and practical housing while helping keep unnecessary weight lower than heavier case materials.
The extended length rear extension housing is one of the defining features of the Magnum XL design. It supports the direct-shift layout required for late model vehicles that originally used factory semi-remote shifter arrangements.
The included shifter, crossmember, and scatter shield give buyers a more complete starting point for installation planning compared with a transmission-only listing.
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 manual transmission with direct-shift performance and double-overdrive gearing.
One of its strongest advantages is the 700 lb-ft torque capacity. This makes the transmission suitable for demanding performance applications when the full drivetrain is properly matched.
Another key benefit is the direct-shift Magnum XL layout. This design helps replace the disconnected feel of some factory semi-remote shifters with a more precise and confident manual shifting experience.
The 2.66 first gear supports strong performance engagement, while the 0.74 fifth gear and 0.50 sixth gear provide double-overdrive capability. The deep 0.50 sixth gear is especially useful for reducing engine rpm during highway cruising when matched with the right rear axle ratio and tire size.
The included shifter, crossmember, and scatter shield also improve package value for buyers planning a performance drivetrain upgrade.
The Tremec T-56 Magnum XL TUKT12019 is built for drivers who want crisp gear changes, low-effort shifting, serious torque capacity, and a more connected manual driving feel.
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 disc spline count, output yoke requirements, driveshaft length, tunnel clearance, transmission mount fitment, crossmember compatibility, and shifter position.
