Description
Tremec TKX Manual Transmissions TCET17722 – Product Overview
The Tremec TKX Manual Transmissions TCET17722 is a performance-focused 5-speed manual transmission from Tremec. It is part of the Tremec TKX 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 TCET17722 and Summit Racing Part Number REM-TCET17722. These part numbers help buyers, installers, and parts departments confirm the correct unit before ordering.
The TKX platform is built for select GM and Ford applications and gives buyers a modern 5-speed manual transmission with high torque capacity, compact packaging, and overdrive drivability. This model uses a 2.87 first gear, 1.00 fourth gear, and 0.81 fifth gear.
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 because the clutch disc and output yoke must be selected to match the transmission.
The Tremec TKX Manual Transmissions TCET17722 includes a shifter, but it does not include a bellhousing and does not include a yoke. Buyers should confirm all supporting parts before ordering.
Fitment and Application Details
The Tremec TKX Manual Transmissions TCET17722 is designed for select GM and Ford applications. Tremec states that TKX transmissions can bolt to a standard GM Muncie bellhousing or be used with a compatible QuickTime bellhousing.
Fitment should be confirmed before purchase by checking the vehicle platform, engine, bellhousing pattern, clutch disc spline count, pilot bearing, flywheel, clutch release system, transmission mount, crossmember position, driveshaft length, output yoke, tunnel clearance, shifter position, reverse light wiring, and cruise control safety wiring.
Because the input shaft uses 26 splines, this transmission requires a compatible 26-spline clutch disc. Because the output shaft uses 31 splines, the correct output yoke must be selected separately.
The transmission includes a short-throw billet aluminum shifter, and the TKX platform is designed with three shifter locations. This gives installers more flexibility when aligning the shifter with the vehicle interior, console, seat position, and transmission tunnel.
The compact, end-loaded design helps provide clearance in most transmission tunnels without floor modification in many applications. This makes the TKX useful for classic vehicles, restomods, and performance builds where space can be limited.
For buyers browsing the manual transmissions category, this product fits naturally with related drivetrain components such as bellhousings, clutch kits, flywheels, pilot bearings, yokes, transmission mounts, driveshaft parts, wiring components, and installation hardware.
Build Quality and Reliability
The Tremec TKX Manual Transmissions TCET17722 is built with a 3-piece aluminum housing that includes the main case, intermediate plate, and rear extension. This design provides structural stiffness while keeping the transmission practical for performance vehicle use.
The transmission has a 600 lb-ft torque capacity, making it suitable for many high-performance street, restoration, and drivetrain upgrade applications when installed with compatible supporting parts.
The TKX is capable of engine speeds up to 8,000 rpm, with shifts at up to 7,500 rpm. This gives the transmission strong performance capability for buyers who need a manual gearbox that can support higher-rpm driving.
All gears and shafts are made from special grade steel ASTM 4615, supporting increased torque-carrying capability. The transmission also uses wide gear widths to help increase gear life and torque handling.
All gears are supported by caged needle bearings, which help reduce end play on the gears and support stable internal operation.
Shift quality is supported by multi-cone synchronizers and hybrid synchronizer rings made from sintered bronze and carbon. These components help create smoother engagement and cleaner shifts.
The internal 3-rail shift system and steel shift components add strength and precision. The built-in reverse light switch and cruise control safety provisions also support practical installation needs.
What Makes This Transmission a Strong Choice
The Tremec TKX Manual Transmissions TCET17722 is a strong choice for buyers who need a compact, durable, and smooth-shifting 5-speed transmission with overdrive.
One of its most important strengths is the 600 lb-ft torque capacity. This gives the transmission the strength needed for many performance applications when matched with the correct clutch, bellhousing, yoke, driveshaft, and mounts.
The 0.81 fifth gear provides overdrive capability for more relaxed highway driving. This is useful for buyers who want a performance manual transmission without giving up practical cruising comfort.
The included short-throw billet aluminum shifter adds value by delivering clean, crisp engagement while helping isolate road noise.
The TKX’s compact, end-loaded design is another important advantage. It helps provide clearance in many transmission tunnels, which can make installation easier in compatible vehicles.
The three shifter locations also support better fitment flexibility. Shifter placement matters in real vehicles because it affects driver reach, interior alignment, console clearance, and driving comfort.
Ideal Buyers and Use Cases
The Tremec TKX Manual Transmissions TCET17722 is best for vehicle owners, mechanics, performance builders, restoration shops, and drivetrain installers working on compatible GM and Ford applications.
It is suitable for buyers who need a 5-speed manual transmission with 600 lb-ft torque capacity, a 26-spline input shaft, 31-spline output shaft, overdrive fifth gear, and included shifter.
This product is also useful for restomod builds, high-performance street vehicles, classic car upgrades, and manual drivetrain projects where compact fitment and shift quality matter.
It is not a complete installation kit. The bellhousing is not included, and the yoke is not included, so buyers should confirm the correct supporting parts before purchase.
The best buyer for this transmission is someone who has already confirmed bellhousing fitment, clutch disc spline count, output yoke requirements, shifter location, driveshaft length, tunnel clearance, and installation needs.

Ordering Support and Fitment Guidance
Before ordering the Tremec TKX Manual Transmissions TCET17722, buyers should confirm the complete drivetrain setup for the intended vehicle.
Important details include vehicle platform, engine, bellhousing, clutch disc spline count, pilot bearing, flywheel, clutch release system, output yoke, driveshaft length, transmission mount, crossmember, tunnel clearance, shifter position, reverse light wiring, and cruise control safety wiring.
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 output yoke must be selected correctly.
The transmission includes the shifter, but the bellhousing is not included and the yoke is not included. Buyers should confirm those parts before installation.
For a complete drivetrain installation, buyers may also need clutch components, flywheel, pilot bearing, release bearing, bellhousing, yoke, driveshaft parts, transmission mount, fluid, wiring connectors, and installation hardware.
The Tremec TKX Manual Transmissions TCET17722 is built for buyers who want a compact 5-speed manual transmission with strong torque capacity, overdrive drivability, crisp shifting, and practical fitment support.
