Description
Product Overview
The Summit Racing™ Automatic Transmissions SUM-700700X is built for buyers who need a dependable remanufactured automatic transmission with practical upgrades, street-friendly operation, and strong value. As part of the Summit Racing™ Automatic Transmissions line, this unit combines quality and economy for compatible Chevy applications where a worn transmission needs to be replaced with a properly prepared automatic transmission.
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, restoration shops, custom vehicle shops, street-performance builders, transmission installers, service departments, and drivetrain specialists confirm the correct Summit Racing transmission before ordering.
The transmission features a 4-speed configuration, Chevy bellhousing bolt pattern, forward shift pattern, and automatic valve body. This makes it a practical choice for compatible builds where fully automatic operation is preferred.
This unit is listed as lockup compatible, so buyers should confirm converter choice, lockup-control requirements, wiring needs, and application compatibility before installation.
The transmission uses a stock polished aluminum pan, slip-on yoke style, 30-spline steel input shaft, 3.06 first gear ratio, OEM-style gray aluminum case, and case-fill location. It is listed as remanufactured and sold individually.
The notes confirm that a throttle valve cable is included. This is an important installation detail for applications that require correct TV cable adjustment for proper transmission operation.
The notes also state that applications using a torque arm will require changing the tail shaft housing, and that this transmission will not fit 4WD applications. Buyers should confirm drivetrain layout and torque-arm requirements before ordering.
This transmission ships without the speedometer driven gear or its housing. If replacing the same model transmission, those components may be reused from the existing unit. If not, they must be purchased separately.
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, so buyers should plan all required supporting components before installation.
Fitment and Application Details
The Summit Racing SUM-700700X automatic transmission should be matched carefully to the intended Chevy application before ordering. Automatic transmission fitment can vary by vehicle year, engine platform, bellhousing compatibility, torque converter setup, flexplate requirements, lockup-control requirements, throttle valve cable setup, speedometer gear setup, yoke style, torque-arm use, tail shaft housing requirements, transmission mount location, crossmember position, driveshaft length, cooler routing, fluid fill location, and shifter compatibility.
Important fitment details to verify include vehicle year, make, model, engine platform, Chevy bellhousing bolt pattern, original transmission family, drivetrain layout, 2WD compatibility, torque converter compatibility, flexplate compatibility, converter bolt pattern, crankshaft pilot fitment, lockup-control setup, throttle valve cable routing and adjustment, 30-spline steel input shaft compatibility, slip-on yoke compatibility, speedometer driven gear and housing requirements, torque-arm requirements, tail shaft housing compatibility, shifter compatibility, transmission mount location, crossmember position, driveshaft length, cooler line routing, transmission cooler requirements, fluid specifications, dipstick setup, and vehicle-specific installation hardware.
Because this transmission will not fit 4WD applications, buyers should confirm that the vehicle is a compatible 2WD application before ordering.
Because applications using a torque arm will require changing the tail shaft housing, buyers should confirm the vehicle’s rear suspension and drivetrain configuration before purchase.
Because the throttle valve cable is included, proper installation and adjustment are critical. Incorrect TV cable setup can affect shift timing, line pressure, drivability, and transmission durability.
Because the torque converter is not included, buyers should select the correct converter for the engine, stall requirement, lockup needs, vehicle weight, rear gear, tire size, and driving use.
Because the flexplate is not included, buyers should confirm the correct flexplate for the engine, crankshaft, converter bolt pattern, balance type, and starter setup.
Because the transmission cooler is not included, a suitable cooler setup should be planned before installation, especially for performance driving, cruising, warm climates, or heavier vehicles.
Because this transmission ships without the speedometer driven gear or housing, buyers should confirm whether the original speedometer parts can be reused or whether new speedometer drive components must be purchased separately.
For a complete installation, additional components may be required, including a torque converter, flexplate, lockup-control parts, transmission cooler, cooler lines, transmission fluid, dipstick, speedometer driven gear, speedometer gear housing, shifter components, tail shaft housing for torque-arm applications, transmission mount, crossmember hardware, driveshaft/yoke components, seals, and vehicle-specific installation parts.
Build Quality and Reliability
The Summit Racing™ Automatic Transmissions SUM-700700X is designed for buyers who want a strong-value replacement automatic transmission with upgraded remanufactured construction. Summit Racing combines quality and economy by offering remanufactured automatic transmissions in many styles and options.
These units are remanufactured with all-new clutches, thrust washers, seals, bushings, and high-energy bands, plus a hardened sunshell. These components help support dependable operation and improved durability compared with a worn-out transmission.
Additional features include a rebuilt front pump, street performance valve body, and high-quality seals and gaskets.
All Summit Racing automatic transmissions are dyno tested before shipment, helping support buyer confidence and installation readiness.
The 3.06 first gear ratio gives this transmission strong launch and low-speed drivability potential when properly matched with the converter, rear gear, tire size, and vehicle weight.
The lockup compatibility supports converter lockup operation when properly configured with the correct converter and lockup-control setup.
The stock polished aluminum pan, OEM gray aluminum case, 30-spline steel input shaft, and slip-on yoke style provide important fitment and installation details for builders and installers.
Because this transmission is sold individually and does not include several supporting components, correct setup is essential. Buyers should confirm converter choice, flexplate compatibility, cooler capacity, speedometer gear setup, TV cable adjustment, lockup-control setup, fluid fill requirements, driveshaft/yoke compatibility, and vehicle-specific hardware before use.
