It is sold individually and should be matched carefully to the correct vehicle before ordering.
This transmission is identified by Manufacturer’s Part Number SUM-700700X, Summit Racing Part Number SUM-700700X, and UPC 190861270664. These identifiers help Chevy owners, mechanics, repair shops, restoration builders, street performance builders, service departments, and drivetrain specialists confirm the correct Summit Racing automatic transmission before purchase.
The transmission features a 4-speed configuration, Chevy bellhousing bolt pattern, forward shift pattern, and automatic valve body. It is also listed as lockup compatible, making it important for buyers to confirm converter, wiring, and lockup-control requirements before installation.
This unit uses a stock-style polished aluminum pan, 30-spline steel input shaft, 3.06 first gear ratio, slip-on yoke style, and OEM-style gray aluminum case. It is remanufactured and built with replacement and street-use value in mind.
Summit Racing automatic transmissions are remanufactured with all-new clutches, thrust washers, seals, bushings, high-energy bands, and a hardened sunshell. Additional features include a rebuilt front pump, street performance valve body, and high-quality seals and gaskets.
Each transmission is dyno tested before shipping, giving buyers added confidence when ordering the correct model for their vehicle.
The torque converter is not included, the flexplate is not included, the transmission controller is not included, the wiring harness is not included, the transmission cooler is not included, transmission fluid is not included, and the dipstick is not included. The transmission is also shipped without the speedometer driven gear or its housing.
Fitment and Application Details
The Summit Racing SUM-700700X automatic transmission should be matched carefully to the intended Chevy 2WD application before ordering. Automatic transmission fitment can vary by vehicle year, model, engine, drivetrain, torque converter setup, flexplate requirements, speedometer setup, tailshaft housing, electronics, cooler routing, transmission mount, crossmember position, driveshaft length, yoke style, and fluid requirements.
This transmission is listed with a Chevy bellhousing bolt pattern, 4-speed automatic configuration, lockup compatibility, 30-spline input, 3.06 first gear ratio, and slip-on yoke style. Buyers should confirm the original transmission family, converter requirements, lockup-control setup, driveshaft/yoke compatibility, and tailshaft housing requirements before purchase.
This transmission will not fit 4WD applications, so buyers should confirm the vehicle is a compatible 2WD application before ordering.
Applications that use a torque arm will require changing the tail shaft housing, so buyers should verify chassis and suspension layout before purchase.
The transmission is shipped without the speedometer driven gear or its housing, so buyers should plan for the correct speedometer components based on tire size, rear gear ratio, vehicle setup, and speedometer system.
The throttle valve cable is included, which is an important installation detail. Buyers should still confirm throttle valve cable adjustment, carburetor or throttle body bracket needs, linkage compatibility, and correct setup before operating the vehicle.
Important fitment details to verify include vehicle year, make, model, engine platform, Chevy bellhousing bolt pattern, original transmission family, 2WD drivetrain layout, torque converter requirements, flexplate compatibility, converter bolt pattern, crankshaft pilot fitment, lockup-control requirements, speedometer gear and housing requirements, tailshaft housing requirements, transmission mount location, crossmember position, driveshaft length, slip-on yoke compatibility, cooler line routing, transmission cooler requirements, throttle valve cable setup, fluid specifications, dipstick setup, and installation hardware.
For a complete installation, additional components may be required, including a torque converter, flexplate, lockup wiring or control components, transmission cooler, cooler lines, transmission fluid, dipstick, speedometer driven gear, speedometer gear housing, tailshaft housing for torque-arm applications, transmission mount, crossmember hardware, driveshaft/yoke components, seals, and vehicle-specific installation parts.

The dyno testing before shipping gives buyers added confidence that the transmission has been checked before it leaves the facility.
The lockup compatibility supports converter lockup function when paired with the correct converter and control setup.
The included throttle valve cable is an important installation feature, but proper adjustment is critical for transmission operation and long-term durability.
