Description

Tremec T-56 Magnum Manual Transmissions TUET16884 – Product Overview

The Tremec T-56 Magnum Manual Transmissions TUET16884 is a brand-new 6-speed manual transmission from Tremec, built for buyers who need strength, precision, and reliable performance in a serious manual drivetrain setup.

This transmission is part of the Tremec T-56 Magnum Manual Transmissions product line and is identified by Manufacturer’s Part Number TUET16884 and Summit Racing Part Number REM-TUET16884.

The T-56 Magnum platform is known for strong construction and high-performance shifting. This model is built from the ground up with a 2.97 first gear and a double-overdrive gear layout that includes 0.80 fifth gear and 0.63 sixth gear.

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

This unit does not include a bellhousing, does not include a yoke, and does not include a shifter. Buyers should confirm all supporting components before ordering.

The Tremec T-56 Magnum Manual Transmissions TUET16884 is designed for electronic or mechanical speedometers, and the 7-tooth internal speedometer drive gear is included. This gives installers more flexibility when planning the speedometer setup.

Fitment and Application Details

The Tremec T-56 Magnum Manual Transmissions TUET16884 is intended for performance applications that require a strong 6-speed manual transmission with high torque capacity and double-overdrive gearing.

The supplied product details do not list exact vehicle year, make, model, engine, or chassis applications, so fitment should be confirmed before purchase. Important details include the vehicle platform, engine, bellhousing requirements, clutch disc spline count, flywheel, pilot bearing, clutch release system, transmission mount, crossmember position, tunnel clearance, driveshaft length, output yoke, speedometer setup, and shifter arrangement.

Because this transmission uses a 26-spline input shaft, the clutch disc must match the input spline count. Because it uses a 31-spline output shaft with a slip-on yoke style, buyers should select a compatible yoke separately.

The bellhousing is not included, so buyers must choose the correct bellhousing based on the engine, clutch system, input shaft requirements, and vehicle application.

The transmission also does not include a shifter, so the correct shifter setup should be selected according to the vehicle layout and desired shifter position.

For buyers browsing the manual transmissions category, this product fits naturally with related drivetrain components such as bellhousings, clutch kits, flywheels, pilot bearings, slip-on yokes, shifters, speedometer components, transmission mounts, and installation hardware.

Build Quality and Reliability

The Tremec T-56 Magnum Manual Transmissions TUET16884 is built for strength, durability, and precise manual shifting. Tremec describes these transmissions as brand new from the ground up, giving buyers a fresh performance gearbox rather than a remanufactured unit.

This model can withstand up to 700 lb-ft of torque, making it suitable for demanding performance applications when paired with the correct clutch, driveshaft, rear axle, mounts, and supporting drivetrain components.

The gears feature substantially increased face widths, which help improve power-handling capability. The gear construction also uses 2-piece laser-beam welded construction, allowing greater control of tooth angles, pitch, and alignment.

A bolstered one-piece countershaft helps resist distortion under load. This is important in high-stress drivetrain environments where shaft stability can affect gear alignment and long-term durability.

The transmission also includes a stronger input shaft, supporting improved durability at the point where engine power enters the gearbox.

New synchronizers with fine-tooth angles help improve shift quality and engagement. Redesigned shift forks further support smooth, confident gear changes.

The case has been extensively modified to help prevent leaks under high-stress conditions and increase overall power-handling capability. This supports long-term reliability in performance-focused use.

What Makes This Transmission a Strong Choice

The Tremec T-56 Magnum Manual Transmissions TUET16884 is a strong choice for buyers who need a performance 6-speed manual transmission with serious torque capacity and refined shift quality.

One of its most important strengths is the 700 lb-ft torque capacity. This gives the transmission the ability to handle demanding performance applications when installed with the right supporting parts.

Another important feature is the 2.97 first gear ratio. This ratio supports strong low-speed acceleration in compatible builds while still working with a double-overdrive gear layout.

The 0.80 fifth gear and 0.63 sixth gear provide overdrive performance for improved cruising behavior. This makes the transmission useful for performance vehicles that need both power handling and highway drivability.

The support for electronic or mechanical speedometers adds installation flexibility. This is helpful for builders working with different vehicle generations, gauge setups, or drivetrain configurations.

The included 7-tooth internal speedometer drive gear is another important supplied detail. It gives buyers a clearer starting point for planning the speedometer system.

The internal upgrades, stronger shaft design, improved synchronizers, redesigned shift forks, and modified case all reinforce this transmission’s role as a serious performance manual gearbox.

Ideal Buyers and Use Cases

The Tremec T-56 Magnum Manual Transmissions TUET16884 is best for performance vehicle owners, drivetrain builders, restoration shops, mechanics, and professional installers who need a strong 6-speed manual transmission.

It is suitable for buyers building or upgrading a performance street car, high-output drivetrain, restomod project, hot rod, pro-touring vehicle, or custom manual transmission setup.

This product is a strong fit for buyers who need 700 lb-ft torque capacity, a 26-spline input shaft, a 31-spline output shaft, double-overdrive gearing, aluminum case construction, and speedometer flexibility.

It is also useful for buyers who need a brand-new Tremec transmission with stronger internals, improved synchronizer design, and a modified case for better durability under high-stress conditions.

This transmission is not a complete installation kit. The bellhousing is not included, the yoke is not included, and the shifter is not included.

The best buyer for this product is someone who has already confirmed the vehicle’s drivetrain requirements, clutch spline needs, bellhousing compatibility, yoke selection, speedometer setup, and shifter arrangement before ordering.

Technical Specifications

Ordering Support and Fitment Guidance

Before ordering the Tremec T-56 Magnum Manual Transmissions TUET16884, buyers should confirm the full drivetrain setup for the intended application.

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, tunnel clearance, speedometer system, and shifter setup.

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 with a slip-on yoke style, so the output yoke must be selected correctly.

The bellhousing is not included, the yoke is not included, and the shifter is not included. Buyers should plan these parts before installation.

The transmission is designed for electronic or mechanical speedometers, and the 7-tooth internal speedometer drive gear is included. Buyers should confirm whether additional speedometer components, cables, sensors, or calibration parts are required.

For a complete drivetrain installation, buyers may also need clutch components, flywheel, pilot bearing, release bearing, bellhousing, slip-on yoke, driveshaft parts, shifter assembly, transmission mount, fluid, wiring, and installation hardware.

The Tremec T-56 Magnum Manual Transmissions TUET16884 is built for buyers who want strong torque capacity, precise shifting, double-overdrive gearing, speedometer flexibility, and durable internal construction.
