The GM 6L80E is a six-speed electronically controlled automatic transmission known for its wide gear range, strong launch performance, overdrive capability, and compatibility with many popular Chevrolet, GMC, Cadillac, and GM performance applications.

Whether you need a used, rebuilt, remanufactured, or performance-built 6L80E transmission, choosing the correct transmission specification is essential for proper fitment and reliable operation.

6L80E Transmission for Sale USA

The 6L80E is a popular choice for Chevrolet and GMC vehicles and is also frequently used in performance and engine-swap projects.

At Forged & Stocked Engines, customers can source 6L80E transmissions for applications including:

• Chevrolet Silverado
• Chevrolet Camaro
• Chevrolet Corvette
• Chevrolet Tahoe
• Chevrolet Suburban
• GMC Sierra
• GMC Yukon
• Cadillac Escalade
• LS engine swaps
• GM performance builds
• Custom transmission conversions

The exact transmission required depends on the vehicle year, engine, drivetrain, 2WD or 4WD configuration, electronics, transmission calibration, and other application-specific details.

6L80E Transmission Specifications

The GM 6L80E uses six forward speeds with two overdrive gears. Typical gear ratios are:

Gear	Ratio
1st	4.027
2nd	2.364
3rd	1.532
4th	1.152
5th	0.852
6th	0.667
Reverse	3.06

The deep 4.02:1 first gear provides strong acceleration from a stop, while the 0.67:1 sixth gear helps reduce engine speed during highway cruising. Chevrolet Performance lists a 650 lb-ft torque rating for its upgraded SuperMatic 6L80-E transmission.

A production 6L80E should not automatically be considered equivalent to a performance-built 6L80E. Internal upgrades, calibration, torque converter selection, and intended horsepower level can significantly affect the transmission’s usable capacity.

6L80E Weight and Dimensions

A typical 6L80E weighs approximately 195–230 pounds, depending on configuration and equipment. The aluminum die-cast case helps keep weight relatively low for a modern six-speed automatic transmission.

A commonly referenced 2WD 6L80E configuration has an overall length of approximately 30.5 inches, although dimensions can vary according to the specific configuration and tailshaft.

For shipping, customers should always confirm the exact transmission configuration and whether the torque converter, transmission pan, wiring, controller, and accessories are included.

Why Buy a 6L80E Transmission?

There are several reasons the 6L80E remains popular among GM owners and performance enthusiasts.

1. Six-Speed Performance

The six-speed design provides a broad range of ratios for both acceleration and highway driving.

2. Strong First Gear

With a 4.027:1 first gear, the 6L80E can provide strong initial acceleration and help keep an engine within its useful powerband.

3. Highway Overdrive

The 0.667:1 sixth gear provides a significant overdrive ratio for highway cruising.

4. LS and GM Compatibility

The 6L80E is widely associated with GM LS/LT applications and has become a common transmission choice for engine swaps and performance builds.

5. Performance Upgrade Potential

The 6L80E can be rebuilt and upgraded with stronger internal components, improved clutch packs, upgraded pumps, valve-body modifications, and performance torque converters.

Performance versions currently offered in the U.S. demonstrate the range of available builds. For example, Chevrolet Performance’s SuperMatic 6L80-E uses upgraded components and is rated at 650 lb-ft, while aftermarket performance builds are available for substantially higher horsepower applications.

6L80E Used, Rebuilt, Remanufactured or Performance Built

When shopping for a 6L80E transmission for sale USA, buyers generally encounter four categories.

Used 6L80E

A used transmission can be a cost-effective option for an OEM replacement, but its previous mileage and operating history should be considered.

Rebuilt 6L80E

A rebuilt transmission may receive new seals, bearings, clutches, bushings and other service components. The quality of the rebuild depends heavily on the parts and processes used.

Remanufactured 6L80E

A remanufactured transmission is generally rebuilt to specified standards with inspection and replacement of worn components. Some U.S. suppliers offer warranties on remanufactured units.

Performance 6L80E

A performance-built 6L80E is designed for increased horsepower and torque. Depending on the build, upgrades may include reinforced clutch packs, upgraded pumps, billet components, performance valve bodies, and specialized torque converters.

6L80E for LS Engine Swaps

The 6L80E is a popular transmission for LS engine swaps because of its six-speed gearing and electronic control system.

It can be found behind various GM V8 applications and is commonly considered for:

• LS3 swaps
• LS2 swaps
• LS1 performance builds
• LQ4 and LQ9 truck engines
• 5.3L LS engines
• 6.0L LS engines
• 6.2L LS engines
• Camaro builds
• Corvette builds
• Silverado performance projects
• Custom street cars

However, an LS engine swap does not automatically mean every 6L80E will fit. The transmission, torque converter, flexplate, electronics, driveshaft, crossmember, transmission mount, cooling system, and controller may all need to be matched to the specific vehicle.

6L80E 2WD vs 4WD

One of the most important considerations when purchasing a 6L80E is whether you need a 2WD or 4WD transmission.

A 2WD transmission and a 4WD transmission can have different tailshaft and transfer-case configurations. Chevrolet Performance, for example, offers a dedicated 4WD SuperMatic 6L80-E configuration designed to mate with a transfer case.

Before ordering, provide:

• Vehicle year
• Vehicle make
• Vehicle model
• Engine size
• 2WD or 4WD
• VIN when applicable
• Transmission identification information
• Intended horsepower
• Intended torque
• Intended use

This information helps determine the correct 6L80E configuration.

6L80E Torque Converter

The torque converter is an important part of a complete 6L80E transmission package.

Depending on the application, a buyer may require an OEM-style converter, stock replacement converter, or performance converter with a specific stall speed.

Performance 6L80E packages may include matched torque converters. For example, some aftermarket performance transmissions are supplied with custom-stalled or billet torque converters designed around the intended engine and vehicle combination.

6L80E Transmission Controller

Because the 6L80E is electronically controlled, electronics and calibration are important when installing one into a custom application.

For factory applications, the correct programming may depend on the vehicle and VIN. For swap applications, a standalone transmission controller may be required.

Before purchasing a transmission for a custom build, confirm whether the package includes:

• Transmission control module
• Wiring harness
• Programming
• Shifter compatibility
• Transmission connector
• Vehicle-specific calibration

6L80E Common Applications

The 6L80E has been used in a wide variety of GM vehicles, making it an attractive transmission for replacement and performance applications.

The 6L90E is a heavier-duty relative of the 6L80E. The two transmissions share many components, but the 6L90E incorporates additional strengthening and has a higher output torque rating. Advance Adapters identifies the 6L90E as approximately 1.375 inches longer than the 6L80E and notes its higher output torque capacity.

If your engine produces substantial horsepower and torque, choosing between a 6L80E and 6L90E should be based on the complete vehicle combination rather than transmission name alone.

How Much Does a 6L80E Cost in the USA?

The price of a 6L80E varies significantly depending on condition, application, warranty, torque converter, internal upgrades and horsepower rating.

Current U.S. market examples show:

• Remanufactured units around $2,700–$3,200
• Higher-performance rebuilt units around $3,500–$6,000+
• Specialized high-performance builds can exceed $6,000
• Chevrolet Performance upgraded units can be priced above $5,500
• Premium performance builds can reach significantly higher prices

These are market examples rather than a fixed selling price, and exact pricing changes by configuration and supplier.

Buy 6L80E Transmission in the USA

When purchasing a 6L80E for sale USA, don’t choose solely based on price. A lower-priced transmission may not include the same components, warranty, torque converter, upgrades, or testing as a premium unit.

At Forged & Stocked Engines, customers can request a 6L80E transmission based on their specific vehicle and performance requirements.

We can help identify the appropriate transmission based on:

• Vehicle application
• Engine
• Power level
• 2WD or 4WD
• Intended use
• Torque converter requirements
• Performance requirements
• Shipping destination

6L80E Transmission Shipping USA

A complete automatic transmission is a heavy freight item and should be professionally packaged for transportation.

Depending on the shipment, a 6L80E can be secured on a heavy-duty pallet or inside a suitable wooden shipping crate. The transmission should be protected against impact, contamination and fluid leakage during transportation.

For customers purchasing a 6L80E transmission online, we recommend confirming the shipping destination and exact transmission configuration before placing an order.
