Tremec Magnum-F Manual Transmissions TUET17638 – Product Overview
The Tremec Magnum-F Manual Transmissions TUET17638 is a high-performance 6-speed manual transmission from Tremec. It belongs to the Tremec Magnum-F Manual Transmissions product line and is supplied as a new, non-remanufactured transmission sold individually.
This product is identified by Manufacturer’s Part Number TUET17638, Summit Racing Part Number REM-TUET17638, and UPC 00887753806772. These identifiers help buyers, installers, shops, and parts departments confirm the correct transmission before ordering.
The Magnum-F was introduced for fourth-generation Camaros and Firebirds and is designed to replace T-56 transmissions in 1998–2002 GM F-body cars. It uses Tremec’s TR-6060/Magnum architecture to give fourth-gen enthusiasts improved performance and a stronger replacement option as quality T-56 replacement parts become harder to source.
This model uses a 6-speed gear layout with 2.97 first gear, 2.10 second gear, 1.46 third gear, 1.00 fourth gear, 0.74 fifth gear, and 0.50 sixth gear. The fifth and sixth gears provide double-overdrive capability, making the transmission suitable for high-performance builds that also need practical 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 specifications are important because the clutch disc and output connection must match the transmission configuration.
The Tremec Magnum-F TUET17638 includes a shifter. It does not include a bellhousing and does not include a yoke, so buyers should confirm the full installation package before ordering.
Fitment and Application Details
The Tremec Magnum-F Manual Transmissions TUET17638 is designed primarily for 1998–2002 GM F-body Camaro and Firebird applications replacing original T-56 transmissions.
The supplied product details also note that the Magnum-F shifter position can benefit other compatible applications that use a similar shifter location. These may include third-generation F-bodies, LT1-powered fourth-generation F-bodies, LS-swapped late model applications, and certain sport compact builds such as A80 Supra and FD RX-7 applications where the shifter position works correctly.
The Magnum-F fills the spacing between the original Magnum shifter locations, which may sit too far forward for some builds, and the Magnum XL layout, which may sit too far back. Its in-between shifter position can provide a better fit for applications where the standard Magnum or Magnum XL does not line up properly.
Fitment should be confirmed before ordering by checking vehicle platform, engine, bellhousing requirements, clutch disc spline count, flywheel, pilot bearing, clutch release system, output yoke, driveshaft length, transmission mount, crossmember position, tunnel clearance, shifter position, speedometer pickup requirements, and cooler circuit needs.
Because this transmission uses a 26-spline input shaft, it requires a compatible 26-spline clutch disc. Because it uses a 31-spline output shaft, the correct output yoke or driveline connection must be selected separately.
The bellhousing is not included, and the yoke is not included. The shifter is included, but buyers should still confirm shifter placement, console alignment, tunnel clearance, and driver reach.
Build Quality and Reliability
The Tremec Magnum-F Manual Transmissions TUET17638 is built using Tremec’s modern TR-6060/Magnum architecture, a platform known for strength, precision, and high-performance manual transmission capability.
The transmission is rated for 700 lb-ft of torque capacity, making it suitable for demanding street, pro-touring, and road-racing applications when paired with compatible clutch, driveline, mounts, and supporting components.
The Magnum-F uses increased face-width on all gears compared with earlier T-56 units. Increased gear face width supports improved load distribution and durability under high-performance use.
The transmission includes a robust combination of double and triple cone synchronizers, supporting short, low-effort shifts with crisp and precise engagement.
The main case includes enhanced webbing, which helps improve case strength and overall power-handling capability. The aluminum case also keeps the transmission reasonably light while providing a strong structure.
The supplied product details list the Magnum-F at 135 lbs dry, making it reasonably light for a strong 6-speed manual transmission.
The transmission also includes provisions for a cooler circuit, giving buyers more flexibility for demanding use where transmission temperature management may be important.
Tremec upgraded the shifter to an isolator-type unit, similar to the one found on the Magnum XL. This shifter helps reduce in-cabin noise and vibration while maintaining the precise, communicative shift feel expected from the Magnum line.
What Makes This Transmission a Strong Choice
The Tremec Magnum-F Manual Transmissions TUET17638 is a strong choice for buyers who need a modern 6-speed replacement for compatible F-body and swap applications.
One of its biggest strengths is the Magnum-F shifter position. It is designed to solve fitment challenges where the original Magnum shifter locations may be too far forward and the Magnum XL may be too far back.
Another key advantage is the 700 lb-ft torque capacity. This gives the transmission strong power-handling ability for high-performance street, pro-touring, road-racing, and LS-based builds when the full drivetrain is properly matched.
The 2.97 first gear gives strong low-speed engagement, while the 0.74 fifth gear and 0.50 sixth gear provide double-overdrive drivability. The deep 0.50 sixth gear can help reduce engine rpm during cruising when paired with the right rear axle ratio and tire size.
The multiple shifter locations and dual speedo pickups add installation versatility. These features are especially useful for custom builds, swaps, and applications where speedometer compatibility and shifter placement matter.
The short, low-effort shift throws and crisp engagement make the Magnum-F appealing for buyers who want a precise manual driving experience.
For buyers who need a Tremec Magnum-F 6-speed transmission with modern OEM-quality content, strong torque capacity, upgraded internal design, and a more suitable F-body shifter position, the TUET17638 is a serious drivetrain solution.
Ideal Buyers and Use Cases
The Tremec Magnum-F Manual Transmissions TUET17638 is best for fourth-generation Camaro and Firebird owners, LS swap builders, pro-touring vehicle builders, road-racing enthusiasts, drivetrain installers, restoration shops, and performance mechanics.
It is suitable for buyers replacing a T-56 in a 1998–2002 GM F-body or building a compatible application that benefits from the Magnum-F shifter position.
This product is also useful for third-generation F-body builds, LT1-powered fourth-generation applications, LS-swapped late model vehicles, and compatible sport compact swap projects where the shifter location and driveline requirements are properly confirmed.
It is not a complete installation kit. The bellhousing is not included, and the yoke is not included. Buyers should confirm all required supporting components before purchase.
The best buyer for this transmission is someone who has already confirmed bellhousing fitment, clutch spline count, output yoke requirements, shifter location, speedometer pickup needs, cooler circuit needs, driveshaft length, transmission mount position, and full vehicle installation requirements.

Ordering Support and Fitment Guidance
Before ordering the Tremec Magnum-F Manual Transmissions TUET17638, buyers should confirm the complete 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 position, tunnel clearance, shifter location, speedometer pickup requirements, cooler circuit needs, and installation hardware.
This transmission uses a 1.125-inch 26-spline input shaft, so the clutch disc must match that spline count. It also uses a 31-spline output shaft, so the output yoke or driveline connection must be selected correctly.
The shifter is included, but the bellhousing is not included and the yoke is not included. These parts should be confirmed before purchase.
For a complete installation, buyers may also need clutch components, flywheel, pilot bearing, release bearing, compatible bellhousing, output yoke, driveshaft parts, transmission mount, fluid, speedometer components, cooler circuit parts, and application-specific hardware.
The Tremec Magnum-F Manual Transmissions TUET17638 is built for buyers who want modern Tremec Magnum strength, improved F-body shifter positioning, double-overdrive performance, and precise manual shift quality.
