Elite Crate Motors offers ATI transmission options across established automatic transmission platforms, giving performance builders, mechanics, race teams, restoration specialists, and vehicle owners access to configurations designed for different power levels and drivetrain requirements.

About ATI Automatic Transmissions

ATI automatic transmissions are performance-oriented transmission assemblies developed for applications where power capacity, shift consistency, drivetrain configuration, and durability are important considerations.

ATI Performance Products produces automatic transmissions across several recognized transmission families. These include Powerglide, TH350, TH400, 4L65E, 4L85E, 6L80E, 8L90E, and ZF 8HP51 configurations, among other transmission products.

These transmission families cover a wide range of applications, from traditional performance street vehicles to purpose-built competition cars.

Powerglide transmissions remain particularly relevant in drag racing and other performance applications where a strong two-speed automatic configuration is desired. TH350 and TH400 transmissions provide three-speed alternatives, while later electronically controlled transmission families offer additional gearing for compatible modern drivetrain combinations.

Selecting an ATI transmission should always be based on the complete vehicle and drivetrain setup rather than the transmission family name alone.

Choosing the Right ATI Transmission

Start by identifying the transmission family, engine combination, vehicle application, drivetrain configuration, and intended use.

For performance applications, engine output is an important consideration. Horsepower and torque can significantly affect transmission requirements, particularly in modified, forced-induction, racing, or high-performance vehicles.

Vehicle weight, rear axle gearing, tire configuration, and intended operating conditions can also influence transmission selection.

Buyers should check bellhousing compatibility, gear ratios, input and output configurations, overall transmission dimensions, valve-body configuration, electronic requirements, and torque converter compatibility where applicable.

A TH400 built for a moderate street-performance application, for example, may have substantially different internal specifications from a TH400 configured for demanding competition use.

Electronic transmission families require additional attention to controls and vehicle integration. When considering transmissions such as later multi-speed electronically controlled units, buyers should verify controller requirements and compatibility with the rest of the drivetrain.

Matching the complete transmission specification to the vehicle provides a stronger foundation for a successful drivetrain combination.

Available Options

Our ATI automatic transmission selection may include configurations across several recognized transmission platforms.

Depending on current inventory, buyers may find:

• ATI Powerglide transmissions
• ATI TH350 transmissions
• ATI TH400 transmissions
• ATI 4L65E transmissions
• ATI 4L85E transmissions
• ATI 6L80E transmissions
• ATI 8L90E transmissions
• ATI ZF 8HP transmission configurations
• Street and street/strip transmissions
• Drag racing transmissions
• Performance transmission assemblies
• Different gear-ratio and internal configurations

Individual transmissions can differ considerably in their construction and intended operating range.

Certain configurations may incorporate upgraded internal components, specialized valve bodies, different gear sets, heavy-duty shafts, or other performance-oriented features. Exact specifications depend on the ATI transmission model and part number.

Buyers should therefore use the individual product listing as the primary reference when comparing available transmissions.

Supported Models and Applications

ATI automatic transmissions support a broad performance market rather than one specific vehicle model.

Depending on the transmission family and configuration, applications can include drag racing vehicles, muscle cars, street-performance cars, hot rods, custom builds, modified trucks, restoration projects, and other performance vehicles.

Traditional transmission families such as Powerglide, TH350, and TH400 are particularly recognizable within GM and performance drivetrain applications. ATI also offers configurations and components that extend into later electronically controlled automatic transmission platforms.

Compatibility should still be confirmed at the individual transmission level.

The engine, bellhousing, driveshaft, crossmember, output configuration, shifter, torque converter, electronics, rear gearing, and intended vehicle use can all influence whether a transmission is appropriate.

Why Buy From Elite Crate Motors

Elite Crate Motors offers ATI automatic transmissions for sale alongside automatic and manual transmissions, replacement engines, drivetrain components, and other automotive powertrain products.

Our product listings are designed to give buyers useful model, part-number, transmission-family, and specification information when comparing available options.

Performance drivetrain combinations can require more detailed compatibility considerations than standard replacement applications. Our customer support team can assist with available product information and specification questions when buyers need additional clarification.

Inventory availability, shipping conditions, included components, and warranty coverage may vary between ATI transmission products. Review the individual product listing and applicable order terms for current specifications and purchasing information.

Frequently Asked Questions

Does ATI make complete automatic transmissions?

Yes. ATI Performance Products offers complete automatic performance transmissions across multiple transmission families. Its lineup includes Powerglide, TH350, TH400 and several later automatic transmission configurations. Individual models are designed for different power levels, vehicle applications, and performance requirements.

What types of ATI automatic transmissions are available?

ATI offers transmission configurations based on platforms including Powerglide, TH350, TH400, 4L65E, 4L85E, 6L80E, 8L90E, and ZF 8HP51. Availability at Elite Crate Motors depends on current inventory, so buyers should check individual listings for exact models and part numbers.

Are ATI transmissions only for drag racing?

No. While ATI has a strong presence in drag racing and competition transmissions, its automatic transmission offerings can also cover street, street/strip, custom, and other performance applications. The appropriate configuration depends on the transmission model, vehicle setup, power level, and intended operating conditions.

How do I choose between an ATI Powerglide, TH350, and TH400?

The right choice depends on factors including engine output, vehicle weight, gearing, intended use, desired gear configuration, and drivetrain setup. These transmission families have different characteristics, so buyers should evaluate the individual ATI model and its specifications rather than selecting solely by transmission name.

How do I verify an ATI transmission before ordering?

Use the ATI part number and transmission family as starting points, then compare the engine application, bellhousing, input and output configuration, gear ratios, overall dimensions, torque converter requirements, controls, and vehicle drivetrain. Modified vehicles may require additional compatibility checks before installation.
