Summit Racing™ Automatic Transmissions SUM-700466

Description

Summit Racing™ Automatic Transmissions SUM-700466 – Professional Overview

The Summit Racing™ Automatic Transmissions SUM-700466 is a 4-speed automatic transmission built around an OEM-style aluminum case and designed for compatible Chevrolet applications. It provides the convenience of automatic shifting while incorporating components intended to support dependable street and performance operation.

Summit Racing positions these remanufactured automatic transmissions as replacement units that combine value with meaningful internal upgrades. The units are rebuilt using new clutches, thrust washers, seals, bushings, and high-energy bands, along with a hardened sunshell and rebuilt front pump.

This model also incorporates a street performance valve body and a high-performance Corvette servo. These features make it a relevant choice for buyers looking for more than a basic replacement transmission while still retaining an automatic configuration suitable for road use.

The SUM-700466 uses a Chevy bellhousing bolt pattern, a forward/standard shift pattern, and a 3.06 first gear. Its 4-speed design and lockup capability make it suited to compatible applications where a conventional electronically controlled automatic transmission is required.

Compatibility and Application Details

Fitment is one of the most important considerations when selecting a replacement automatic transmission. The SUM-700466 uses a Chevrolet bellhousing pattern and is designed around a one-piece case with a 13-pin connector.

The supplied application information specifically identifies compatibility with 4WD applications using a 1-piece bellhousing with an iron block. Buyers should therefore confirm the vehicle’s existing transmission configuration, bellhousing arrangement, drivetrain layout, and connector configuration before ordering.

The transmission has a 30-spline input and uses a slip-on yoke. Its 3.06 first-gear ratio provides a relatively deep starting ratio for a 4-speed automatic, while the lockup-compatible design supports applications requiring that transmission characteristic.

Because transmission fitment depends on the complete drivetrain configuration, the correct application should always be confirmed against the vehicle and existing transmission before purchase.

Construction and Performance Features

The SUM-700466 uses an OEM-style aluminum transmission case with a gray finish and a polished aluminum stock-style pan. The aluminum construction provides the familiar architecture expected from an OEM-based automatic transmission while maintaining the practical characteristics of a remanufactured unit.

Internally, Summit Racing’s automatic transmissions are described as receiving new clutches, thrust washers, seals, bushings, and high-energy bands. The hardened sunshell provides another important internal upgrade, while the rebuilt front pump contributes to the transmission’s overall operating system.

This model also includes a high-performance Corvette servo. Combined with the street performance valve body, this configuration is intended to provide a stronger performance-oriented specification than a conventional stock replacement.

The transmission is remanufactured and dyno tested before shipment, giving buyers an important quality-control reference when selecting a replacement unit. These characteristics make it appropriate for customers seeking a professionally remanufactured automatic transmission rather than an unverified used assembly.

What Makes This Transmission a Practical Choice

The SUM-700466 stands out by combining a familiar OEM-style architecture with several performance-oriented upgrades. For a buyer replacing a compatible automatic transmission, this provides a balance between everyday drivability and enhanced internal specification.

Its 4-speed configuration, 3.06 first gear, automatic valve body, and lockup capability make it suitable for applications that require conventional automatic operation with additional performance consideration.

The high-performance Corvette servo and street performance valve body are particularly relevant to buyers who want a replacement transmission with upgraded operating components. Meanwhile, the remanufactured construction and dyno-testing process provide additional confidence when choosing a replacement unit.

The polished aluminum pan also gives the transmission a finished appearance while retaining the stock-style pan configuration.

Who This Transmission Is Best For

The SUM-700466 is best suited to buyers who need a remanufactured Chevrolet automatic transmission for a compatible application and want a unit with performance-oriented upgrades.

It can be a strong option for:

• Vehicle owners replacing a worn or failed compatible automatic transmission
• Builders working with compatible Chevrolet drivetrains
• Customers requiring a 4-speed lockup automatic transmission
• 4WD applications matching the specified one-piece bellhousing and iron-block configuration
• Street-oriented vehicles where an upgraded automatic valve body and Corvette servo are desirable
• Buyers looking for a dyno-tested remanufactured transmission rather than a used unit

It is not intended as a universal transmission replacement. Application details should be checked carefully before ordering, particularly the bellhousing, drivetrain configuration, connector, input spline, and 4WD requirements.

Technical Specifications

Ordering and Fitment Support

Choosing the correct transmission requires more than matching the number of gears. The bellhousing pattern, input spline count, case design, connector configuration, drivetrain layout, yoke arrangement, and 4WD requirements should all correspond with the vehicle.

The SUM-700466 is supplied as a remanufactured transmission and does not include a torque converter, flexplate, controller, wiring harness, transmission cooler, fluid, or dipstick. This is important when planning the complete installation because these components may need to be retained from the existing setup or sourced separately.

The supplied information also states that this model includes a high-performance Corvette servo and uses a one-piece case with a 13-pin connector. Customers should verify these details against their vehicle before purchasing.

For buyers comparing options within the automatic transmissions category, related Summit Racing transmission configurations can also be evaluated according to gear count, drivetrain application, lockup capability, input spline, and performance specification.

Frequently Asked Questions

Is the Summit Racing SUM-700466 a remanufactured transmission?

Yes. The SUM-700466 is identified as a remanufactured automatic transmission. The supplied product information states that Summit Racing remanufactured units receive new clutches, thrust washers, seals, bushings, and high-energy bands, along with a hardened sunshell and rebuilt front pump. The transmissions are also dyno tested before shipment.

How many gears does the SUM-700466 have?

The SUM-700466 is a 4-speed automatic transmission. It has a 3.06 first-gear ratio and is lockup compatible. This configuration makes it appropriate for compatible applications requiring a four-speed automatic with conventional automatic operation.

Does the SUM-700466 include a torque converter?

No. The supplied specifications identify the torque converter as not included. Buyers should account for the required torque converter separately and confirm that its specifications match the transmission and vehicle application.

Is the SUM-700466 compatible with 4WD vehicles?

Yes, but only for the specified application configuration. The product information states that it fits 4WD applications with a 1-piece bellhousing and an iron block. Because 4WD transmission fitment can vary significantly, the bellhousing and drivetrain configuration should be confirmed before ordering.

What type of valve body does this transmission use?

The SUM-700466 uses an automatic valve body. The supplied product description also identifies a street performance valve body as one of the upgrades used in Summit Racing’s remanufactured transmission specification.

What is the first-gear ratio of the SUM-700466?

The first-gear ratio is 3.06:1. This provides a relatively deep first gear for the four-speed automatic configuration and is an important specification to consider when comparing replacement transmissions and drivetrain combinations.

Does the transmission include a wiring harness or controller?

No. The SUM-700466 does not include a transmission controller or wiring harness. It does, however, use a 13-pin connector as part of its one-piece case design. The vehicle’s existing electronics and control requirements should be checked carefully for compatibility.
