Description
Richmond Gear Super T-10 Transmission Overview
The Richmond Gear Super T-10 4-Speed Transmission 1304000070 is part of the Richmond Gear Super T-10 4-Speed Transmissions product line and is designed for builders who want a strong, traditional 4-speed manual transmission for performance-focused vehicles.
This transmission is listed under Manufacturer’s Part Number 1304000070, Summit Racing Part Number RMG-1304000070, and UPC 698231767474. It is sold individually and does not include a bellhousing, does not include a yoke, and does not include a shifter.
The transmission uses a 1.125-inch input shaft diameter, 26-spline input shaft, 32-spline output shaft, and 1.375-inch output shaft spline diameter. It also features a 12.000-inch tailshaft length and slip-on yoke style.
Richmond Gear Super T-10 transmissions are 4-speed countershaft helical gear transmissions synchronized in all forward gears. First and reverse are constantly meshed to help prevent gear clash, while strut-type synchronizers support longer life and easier shifting.
Vehicle Fitment and Common Applications
The Richmond Gear Super T-10 1304000070 is used in compatible performance-type automobiles and light trucks that require a strong 4-speed manual transmission with the correct input, output, tailshaft, shifter, and bellhousing setup.
Fitment should be verified by checking bellhousing compatibility, clutch disc spline count, pilot bearing, flywheel setup, driveshaft length, output yoke, shifter style, transmission mount, crossmember location, tunnel clearance, speedometer requirements, and intended driving use.
This transmission requires a Long-style shifter, and the shifter is not included. Buyers should select a compatible shifter assembly separately.
Because this transmission uses a 26-spline input shaft, buyers need a compatible 26-spline clutch disc. Because it uses a 32-spline output shaft with a slip-on yoke style, buyers must select the correct matching yoke and driveshaft setup.
The bellhousing is not included, so the correct bellhousing must be selected based on the engine, chassis, clutch setup, and installation requirements.
4-Speed Performance and Gear Ratio Value
The Richmond Gear Super T-10 4-Speed Transmission gives builders a classic manual driving experience with synchronized forward gears and a direct fourth gear.
The gear ratios for this model are:
| Gear | Ratio |
|---|---|
| First Gear | 2.43:1 |
| Second Gear | 1.61:1 |
| Third Gear | 1.23:1 |
| Fourth Gear | 1.00:1 |
The 2.43 first gear ratio provides a performance-oriented starting ratio, while the 1.00 fourth gear delivers direct-drive operation. This ratio set is well suited for compatible performance vehicles where rear axle ratio, tire size, vehicle weight, and engine torque curve are matched correctly.
For drivers who prefer a traditional 4-speed manual transmission feel, the Richmond Super T-10 offers mechanical engagement, strong power transfer, and straightforward operation.
This transmission can be a strong choice for muscle car builds, period-correct performance projects, light truck upgrades, street performance vehicles, and restoration applications where a durable 4-speed layout is preferred.
Helical Gears, Synchronizers, and Shift Quality
The Richmond Gear Super T-10 1304000070 is built as a countershaft helical gear transmission. Helical gears support smoother operation compared with straight-cut race gears, making this design suitable for performance street and light truck applications where drivability matters.
All forward gears are synchronized, helping support smoother gear changes during normal operation. The transmission also uses strut-type synchronizers, which are designed for longer life and easier shifting.
First and reverse are constantly meshed to help prevent gear clash. This is an important design detail for builders who want a stronger traditional manual transmission with better engagement quality.
Together, these features make the Richmond Gear Super T-10 4-speed transmission a practical option for buyers who want performance capability without sacrificing basic shift smoothness.
Input, Output, and Driveline Details
The Richmond Gear 1304000070 Super T-10 uses a 1.125-inch input shaft diameter with 26 splines. Buyers should choose a compatible 26-spline clutch disc during installation planning.
The output shaft uses 32 splines with a 1.375-inch output shaft spline diameter. The yoke style is listed as slip-on, and the yoke is not included.
The tailshaft length is 12.000 inches, which should be compared with the original transmission, driveshaft length, transmission mount location, and crossmember position.
Correct driveline planning is essential. Buyers should confirm the bellhousing, pilot bearing, clutch release system, clutch disc, slip yoke, driveshaft, transmission mount, and shifter setup before ordering.
Case Design and Build Quality
The Richmond Gear Super T-10 4-Speed Transmission 1304000070 uses an aluminum case, helping reduce weight while supporting the strength needed for compatible performance applications.
The Super T-10 design is known for combining classic 4-speed manual operation with performance-focused internal construction. The synchronized forward gears, constant mesh first and reverse, and strut-type synchronizers help support smoother operation and longer service life.
For builders working on performance-type automobiles or light trucks, this transmission provides a solid manual gearbox option with clear specifications for input shaft, output shaft, gear ratios, shifter style, yoke type, and tailshaft length.
Because this transmission is listed as remanufactured: no, it is not a rebuilt used transmission.
Included and Not Included Components
The Richmond Gear Super T-10 4-Speed Transmission 1304000070 is sold individually as a transmission assembly.
The supplied specifications state:
| Component | Included |
| Transmission Assembly | Yes |
| Bellhousing | No |
| Yoke | No |
| Shifter | No |
This transmission requires a Long-style shifter, which must be purchased separately. Buyers must also plan for the correct bellhousing, clutch disc, flywheel, pilot bearing, release bearing, clutch linkage or hydraulic system, transmission mount, crossmember, slip yoke, driveshaft, speedometer components, fluid, and installation hardware.
Key Benefits for Performance Builders
The Richmond Gear Super T-10 1304000070 gives builders a durable 4-speed manual transmission with traditional performance character and practical driveline specifications.
The first major benefit is classic 4-speed performance. The 2.43 first gear, 1.61 second gear, 1.23 third gear, and 1.00 direct fourth gear provide a proven manual transmission ratio spread.
The second benefit is shift support. Synchronized forward gears, strut-type synchronizers, and constant mesh first and reverse help support easier shifting and reduced gear clash.
The third benefit is fitment planning clarity. The listed 26-spline input, 32-spline output, 12-inch tailshaft, slip-on yoke style, and Long-style shifter requirement help buyers choose compatible supporting parts.
The fourth benefit is broad performance use. Richmond Super T-10 transmissions are designed for performance-type automobiles and light trucks, making them useful for restoration, street performance, and classic drivetrain builds.
Who This Transmission Is Best For
The Richmond Gear Super T-10 4-Speed Transmission 1304000070 is best for builders who need a traditional 4-speed manual transmission for compatible performance cars, muscle cars, restoration projects, light trucks, and high-performance street applications.
It is suitable for professional builders, restoration shops, performance garages, classic vehicle owners, street performance enthusiasts, and light truck builders who want a durable manual transmission with classic 4-speed character.
This product is a strong choice for buyers who need a 26-spline input shaft, 32-spline output shaft, 2.43 first gear, 12-inch tailshaft, slip-on yoke style, aluminum case, and Long-style shifter compatibility.
It is not intended for buyers who need a complete conversion package with bellhousing, yoke, shifter, clutch, flywheel, crossmember, mount, driveshaft, linkage, fluid, or installation hardware included. Those components must be selected separately based on the vehicle and drivetrain setup.
