Description
Tremec TR-4050 Manual Transmissions TDET17341 – Product Overview
The Tremec TR-4050 Manual Transmissions TDET17341 is a heavy-duty 5-speed manual transmission from Tremec. It belongs to the Tremec TR-4050 Manual Transmissions product line and is supplied as a new, non-remanufactured transmission sold individually.
This product is identified by Manufacturer’s Part Number TDET17341 and Summit Racing Part Number REM-TDET17341. These identifiers help buyers, installers, mechanics, and parts departments confirm the correct transmission before ordering.
The TR-4050 is designed for 4WD applications and uses an NV4500 bolt pattern. The supplied product details describe it as similar to the NV4500 and a direct replacement with 600 lb-ft of torque capacity.
This model uses a 5-speed gear layout with an aggressive 6.16 first gear, 3.11 second gear, 1.71 third gear, 1.00 fourth gear, and 0.76 fifth gear overdrive. Reverse gear is listed as 6.03.
The 6.16 first gear gives the transmission strong low-speed control, while the 0.76 fifth gear provides overdrive capability for more economical cruising when the complete drivetrain is properly matched.
The transmission uses a 1.125-inch input shaft diameter, 10-spline input shaft, and 23-spline output shaft. These details are important because the clutch disc, transfer case, and drivetrain components must match the transmission configuration.
The Tremec TR-4050 Manual Transmissions TDET17341 includes a shifter. It does not include a bellhousing and does not include a yoke, so buyers should confirm all supporting parts before ordering.
Fitment and Application Details
The Tremec TR-4050 Manual Transmissions TDET17341 is designed for 4WD applications and uses an NV4500 bolt pattern.
Fitment should be confirmed before purchase by checking the vehicle platform, engine, bellhousing pattern, clutch disc spline count, flywheel, pilot bearing, clutch release system, transfer case compatibility, output configuration, transmission mount, crossmember position, driveshaft length, tunnel clearance, PTO needs, and shifter position.
Because this transmission uses a 10-spline input shaft, it requires a compatible 10-spline clutch disc. Because it uses a 23-spline output shaft, the transfer case or output connection must match the transmission’s output configuration.
The supplied details also list a 6.5-inch tailshaft length and 19.5-inch overall length. These dimensions are important for driveshaft planning, transfer case alignment, mount position, and installation clearance.
The bellhousing is not included, so buyers must select the correct compatible bellhousing for the engine, clutch system, and installation. The yoke is not included, so any required output or driveline connection should be verified separately.
The transmission includes a standard right-hand 6-bolt PTO, allowing compatible hydraulic pump setups where the application requires power take-off functionality.
For a complete drivetrain setup, buyers may also need a compatible bellhousing, clutch kit, flywheel, pilot bearing, release bearing, transfer case components, mount, crossmember, fluid, PTO equipment, driveshaft components, and installation hardware.
Build Quality and Reliability
The Tremec TR-4050 Manual Transmissions TDET17341 is built for demanding 4WD use with a strong internal design and high torque capacity.
The transmission is rated at 600 lb-ft / 813 Nm torque capacity, giving it the strength needed for heavy-duty 4WD applications when paired with compatible clutch, transfer case, driveline, and supporting components.
The housing is made from diecast aluminum alloy, which helps save weight while offering considerable rigidity. The supplied specifications list the transmission weight as 164 lbs / 74 kg.
The TR-4050 uses high-contact, constant mesh, helical gears for strength and smooth operation. Helical gear design supports quieter performance and strong tooth contact under load.
The transmission is fully synchronized, which supports smoother shifting and reduced shift effort. Tremec also lists advanced synchronizer technology as a feature, helping improve shift quality.
A multiple rail internal shifter provides excellent shift feel and performance. This is important for a 4WD manual transmission where positive engagement and driver confidence matter.
The transmission uses tapered bearings on the input, main, and counter shafts to provide internal stability. It also uses needle bearings under gears to reduce friction and noise output.
The 5th gear synchronizer is mounted to the countershaft to help improve NVH in overdrive. NVH refers to noise, vibration, and harshness, which matters for drivability and refinement.
What Makes This Transmission a Strong Choice
The Tremec TR-4050 Manual Transmissions TDET17341 is a strong choice for buyers who need a heavy-duty 4WD manual transmission with deep low gear control and overdrive capability.
One of its most important features is the 6.16 first gear. This aggressive low gear is useful for controlled starts, heavy-load movement, off-road crawling, and low-speed drivability in compatible 4WD applications.
The 0.76 fifth gear overdrive gives the transmission more practical cruising capability. When matched with the correct axle ratio and tire size, this overdrive gear can help reduce engine rpm during highway use.
Another major benefit is the 600 lb-ft torque rating. This gives the transmission strong power-handling capability for demanding 4WD builds when the full drivetrain is properly matched.
The NV4500 bolt pattern makes this transmission especially relevant for buyers working with NV4500-style drivetrain layouts.
The 6-bolt PTO provision adds real utility for applications that need hydraulic pump support. This makes the TR-4050 useful beyond ordinary street use, especially where work, utility, or specialty 4WD functionality is required.
With fully synchronized gears, advanced synchronizer technology, helical gear construction, tapered shaft bearings, and an included shifter, the Tremec TR-4050 TDET17341 is built for buyers who need strength, shift quality, and practical 4WD capability.
Ideal Buyers and Use Cases
The Tremec TR-4050 Manual Transmissions TDET17341 is best for 4WD truck builders, off-road vehicle owners, utility vehicle builders, mechanics, restoration shops, drivetrain installers, and performance truck specialists.
It is suitable for buyers who need a 5-speed manual transmission with 600 lb-ft torque capacity, 6.16 first gear, 0.76 overdrive, 10-spline input shaft, 23-spline output shaft, NV4500 bolt pattern, and PTO capability.
This transmission is useful for compatible 4WD applications that need strong low-speed control, reliable torque handling, and overdrive cruising.
It is not a complete universal installation kit. The bellhousing is not included, and the yoke is not included. Buyers should confirm all required supporting components before ordering.
The best buyer for this product is someone who has already confirmed NV4500-style fitment, bellhousing compatibility, clutch disc spline count, transfer case compatibility, output shaft requirements, PTO needs, shifter location, fluid capacity, driveshaft length, and mount alignment.
