Description
Tremec TKX Manual Transmissions TCET17765 – Product Overview
The Tremec TKX Manual Transmissions TCET17765 is a performance-focused 5-speed manual transmission from Tremec, designed for select GM and Ford applications. It belongs to the Tremec TKX Manual Transmissions product line and is supplied as a new, non-remanufactured transmission assembly sold individually.
This product is identified by Manufacturer’s Part Number TCET17765 and Summit Racing Part Number REM-TCET17765. These part numbers help buyers, mechanics, and performance shops confirm the correct transmission during ordering and installation planning.
The TKX platform is built for drivers who want strong torque capacity, compact packaging, improved shift quality, and practical overdrive performance. This model includes a 5-speed gear layout, 2.87 first gear ratio, 1.00 fourth gear, and 0.68 fifth gear overdrive.
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 yoke must match the transmission’s shaft configuration.
The Tremec TKX Manual Transmissions TCET17765 includes a shifter, but it does not include a bellhousing and does not include a yoke. Buyers should confirm the correct bellhousing, clutch disc, output yoke, and related installation parts before ordering.
Fitment and Application Details
The Tremec TKX Manual Transmissions TCET17765 is designed for select GM and Ford applications. The supplied product details state that Tremec TKX transmissions can bolt to a standard GM Muncie bellhousing or be used with a compatible QuickTime bellhousing.
This makes the TKX platform useful for many performance builds where a strong 5-speed transmission is needed, but final fitment must always be confirmed before purchase.
Important fitment details include the vehicle platform, engine, bellhousing pattern, clutch disc spline count, pilot bearing, flywheel, clutch release system, transmission mount, crossmember location, driveshaft length, tunnel clearance, shifter position, reverse light wiring, cruise control safety wiring, and output yoke requirements.
Because the input shaft is 26-spline, this transmission requires a compatible 26-spline clutch disc. Because the output shaft is 31-spline, the correct matching output yoke must be selected separately.
The product includes an integrated short-throw billet aluminum shifter, and the TKX design supports three shifter locations. This helps buyers and installers achieve a better shifter position in many compatible vehicle interiors.
Its compact, end-loaded design helps provide clearance in most transmission tunnels without floor modification in many applications. This is especially valuable for classic vehicles, restomod builds, and drivetrain upgrades where tunnel space can be limited.
Build Quality and Reliability
The Tremec TKX Manual Transmissions TCET17765 is built with an aluminum case and a 3-piece aluminum housing that includes the main case, intermediate plate, and rear extension. This design provides structural stiffness while keeping the transmission manageable for performance vehicle use.
The transmission is rated for 600 lb-ft of torque capacity, giving it the strength needed for many performance-focused GM and Ford applications. It is also capable of engine speeds up to 8,000 rpm, with shifts at up to 7,500 rpm.
Tremec uses special grade steel ASTM 4615 for all gears and shafts. This material supports increased torque-carrying capability and long-term durability under demanding conditions.
The TKX also uses wide gear widths, which help increase gear life and torque capacity. All gears are supported by caged needle bearings to reduce end play and improve internal stability.
Shift quality is supported by multi-cone synchronizers and hybrid synchronizer rings made from sintered bronze and carbon. These components help deliver cleaner gear engagement and improved shift feel.
The internal 3-rail shift system and steel shift components add strength and precision to the transmission’s manual shift operation. 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 TCET17765 is a strong choice for buyers who need a compact, durable, and performance-ready 5-speed manual transmission.
One of its strongest advantages is the 600 lb-ft torque capacity. This gives the transmission the strength required for many performance street, restomod, and upgraded drivetrain applications when matched with the correct clutch and supporting parts.
Another key advantage is the 0.68 fifth gear overdrive. This helps reduce engine rpm during highway driving compared with a direct-drive 4-speed setup, making the vehicle more comfortable for cruising while still keeping manual performance.
The included short-throw billet aluminum shifter is another important benefit. It is designed to isolate road noise while providing clean, crisp shift engagement.
The transmission’s compact, end-loaded design also supports easier fitment in many vehicles. For buyers working with limited tunnel space, this design can reduce the need for major modifications.
The TKX platform also supports three shifter locations, giving installers more flexibility when aligning the shifter with the interior layout. For performance builds where driver comfort and precise shift placement matter, this is a valuable detail.
Ideal Buyers and Use Cases
The Tremec TKX Manual Transmissions TCET17765 is best for vehicle owners, mechanics, restoration shops, drivetrain installers, and performance builders working on compatible GM and Ford applications.
It is suitable for buyers upgrading from an older manual transmission, building a restomod, improving street drivability, or adding overdrive capability to a performance vehicle.
This transmission is also a strong fit for users who need a balance of strength and comfort. The 600 lb-ft torque rating, high-rpm capability, overdrive fifth gear, and included short-throw shifter make it suitable for performance-focused vehicles that are still driven regularly.
It is not intended for buyers who need a complete installation kit. The bellhousing is not included, and the yoke is not included, so these components must be selected separately.
The best buyer for this transmission is someone who has already confirmed vehicle compatibility, clutch requirements, bellhousing needs, output yoke fitment, and shifter location before ordering.

Ordering Support and Fitment Guidance
Before ordering the Tremec TKX Manual Transmissions TCET17765, buyers should confirm the full installation setup. Important details include vehicle application, engine, bellhousing, clutch disc, pilot bearing, flywheel, clutch release system, output yoke, driveshaft length, transmission mount, crossmember, tunnel clearance, and shifter position.
This transmission includes the shifter, but the bellhousing is not included and the yoke is not included. Buyers should select those parts based on the vehicle and drivetrain layout.
Because the TKX uses a 26-spline input shaft, a compatible 26-spline clutch disc is required. The 31-spline output shaft also means the output yoke must be matched correctly.
The built-in reverse light switch and cruise control safety provisions should be considered during wiring and installation planning.
For a complete drivetrain installation, buyers may also need clutch components, flywheel, pilot bearing, release bearing, bellhousing, yoke, driveshaft parts, transmission mount, crossmember, fluid, wiring connectors, and installation hardware.
The Tremec TKX Manual Transmissions TCET17765 is designed for buyers who want a compact 5-speed manual transmission with strength, overdrive, crisp shift quality, and proven Tremec engineering.
