Description
Richmond Gear Super T-10 4-Speed Transmissions 1304000072 – Product Overview
The Richmond Gear Super T-10 4-Speed Transmissions 1304000072 is a performance-focused 4-speed manual transmission from Richmond Gear. It belongs to the Richmond Gear Super T-10 4-Speed Transmissions product line and is supplied as a new, non-remanufactured transmission assembly sold individually.
This product is identified by Manufacturer’s Part Number 1304000072, Summit Racing Part Number RMG-1304000072, and UPC 698231769447. These identifiers help buyers, installers, and parts departments confirm the correct transmission during ordering.
The transmission uses a 1.125-inch input shaft diameter with 26 input splines. It also uses a 32-spline output shaft with a 1.375-inch output shaft spline diameter. These details are important because the clutch disc and output yoke must be matched correctly for the vehicle.
The Richmond Gear Super T-10 4-Speed Transmissions 1304000072 has a 12.000-inch tailshaft length, an aluminum case, and a slip-on yoke style. The yoke is not included, so buyers should select the correct compatible yoke separately.
This transmission does not include a bellhousing, does not include a shifter, and requires a Long-style shifter. Buyers should confirm the full installation setup before purchase.
Fitment and Application Details
The Richmond Gear Super T-10 4-Speed Transmissions 1304000072 is intended for performance-type automobiles and light trucks that require a compatible 4-speed manual transmission configuration.
Fitment should be confirmed by checking the original transmission type, bellhousing pattern, clutch disc spline count, pilot bearing, flywheel, clutch release setup, transmission mount, crossmember position, driveshaft length, output yoke, and shifter style.
Because the input shaft is 26-spline, this transmission requires a compatible 26-spline clutch disc. Because the output shaft is 32-spline, the output yoke must also be matched to the correct spline count and slip-on yoke style.
The transmission requires a Long-style shifter, and the shifter is not included. Buyers should confirm shifter compatibility, shifter position, tunnel clearance, and interior layout before ordering.
The 12-inch tailshaft length should also be checked against the vehicle’s drivetrain layout. Tailshaft length can affect driveshaft fitment, mount position, and overall installation planning.
For buyers browsing the manual transmissions category, this product fits naturally with related drivetrain components such as bellhousings, clutch kits, flywheels, pilot bearings, Long-style shifters, slip-on yokes, transmission mounts, and installation hardware.
Build Quality and Reliability
The Richmond Gear Super T-10 4-Speed Transmissions 1304000072 is built as a 4-speed countershaft helical gear transmission. Helical gear design supports smoother operation while maintaining the strength needed for performance driving.
The transmission is synchronized in all forward gears. This helps support smoother shifting and makes the transmission easier to operate in compatible performance vehicles and light trucks.
First and reverse are constantly meshed to help prevent gear clash. This design detail supports cleaner engagement and reduces the harshness often associated with poorly matched or worn manual transmission components.
Richmond Gear also uses strut-type synchronizers to support longer service life and easier shifting. Synchronizer performance is important because it affects gear engagement, shift feel, and overall drivability.
The transmission uses an aluminum case, which provides a practical balance of strength and manageable weight. Aluminum case construction is commonly valued in performance manual transmissions because it supports durability without unnecessary heaviness.
The Richmond Gear Super T-10 4-Speed Transmissions 1304000072 is listed as not remanufactured, meaning it is not supplied as a rebuilt used unit.
What Makes This Transmission a Strong Choice
The Richmond Gear Super T-10 4-Speed Transmissions 1304000072 is a strong choice for buyers who need classic manual transmission performance with clearly defined driveline specifications.
One important feature is the 2.88 first gear ratio. This gives the transmission useful starting leverage for compatible performance vehicles and light trucks.
The 1.91 second gear, 1.33 third gear, and 1.00 fourth gear create a traditional 4-speed manual ratio spread. The fourth gear provides direct-drive operation, which is common in classic performance manual transmission setups.
Another strong point is the combination of 26-spline input and 32-spline output. These specifications help buyers and installers select the correct clutch disc and output yoke during installation planning.
The synchronized forward gears, constant mesh first and reverse, and strut-type synchronizers also make this transmission a practical choice for buyers who want strength with smoother manual operation.
The aluminum case, 12-inch tailshaft, and slip-on yoke style provide additional fitment details that help professional installers confirm whether this transmission is right for the intended vehicle.
Ideal Buyers and Use Cases
The Richmond Gear Super T-10 4-Speed Transmissions 1304000072 is best for vehicle owners, restoration shops, mechanics, performance builders, and drivetrain installers working on compatible performance-type automobiles or light trucks.
It is suitable for buyers who need a 4-speed manual transmission with a 2.88 first gear, synchronized forward gears, and a direct 1.00 fourth gear.
This product is also useful for builds where the buyer wants a traditional manual driving experience with clear mechanical engagement and proven Richmond Gear transmission design.
It is not a complete installation kit. The bellhousing is not included, the yoke is not included, and the shifter is not included. The transmission also requires a Long-style shifter, which must be selected separately.
The best buyer for this product is someone who has already confirmed clutch spline compatibility, output yoke requirements, bellhousing fitment, tailshaft length, and shifter style before ordering.

Ordering Support and Fitment Guidance
Before ordering the Richmond Gear Super T-10 4-Speed Transmissions 1304000072, buyers should confirm the full drivetrain setup and intended application.
Important details include the original transmission configuration, bellhousing compatibility, clutch disc spline count, pilot bearing, flywheel, clutch release system, output yoke, driveshaft length, tailshaft length, transmission mount, crossmember, shifter style, and tunnel clearance.
This transmission does not include the bellhousing, does not include the yoke, and does not include the shifter. The required shifter style is Long, so the shifter should be selected carefully before installation.
Because the input shaft uses 26 splines, the clutch disc must match the transmission. Because the output shaft uses 32 splines, the yoke must also be selected to match the output configuration.
For a complete drivetrain installation, buyers may also need clutch components, flywheel, pilot bearing, release bearing, bellhousing, Long-style shifter, slip-on yoke, driveshaft parts, transmission mount, fluid, and installation hardware.
The Richmond Gear Super T-10 4-Speed Transmissions 1304000072 is built for buyers who want a traditional 4-speed manual transmission with synchronized forward gears, strong gear engagement, and clear fitment specifications.
