Best Automatic Transmission For Ls Swap: Compare 10 Options

#1 · Best Overall

1. JEGS 4L80E HD 900HP

• Weight: 195 lb
• Dimensions: 34 x 22 x 20 in

Best for: 900-HP RWD LS Build.

Why it ranks #1: Explicitly fits 2000–2019 GM Gen III/IV LS and 2WD/RWD applications, with a 900 HP rating and 300M input and mainshafts.

A 900-hp rating distinguishes this JEGS HD 4L80E from lower-rated LS transmission options in the supplied lineup. It is remanufactured for 2000–2019 GM Gen III/IV LS applications, with a 7-bolt bellhousing and 2WD/RWD designation to focus its intended installation.

The 300M input and mainshafts, 6-clutch direct drum, and HD forward clutch hub specify substantial internal hardware for a high-output build. New overdrive/reverse sprags add another named internal upgrade, while the 900-hp rating establishes the advertised ceiling. Its 7-bolt bellhousing and stated 2000–2019 Gen III/IV LS 2WD/RWD application help define the installation target. Builders should keep that rear-drive application distinct from 4WD projects when selecting the transmission.

Skip it if you need a 4WD LS truck transmission; Stellar Automotive Group Rebuilt 4L60E is specified for GM LS 4WD vehicles.

Choose this HD 4L80E for a high-output Gen III/IV LS RWD build that needs the stated 900-hp rating and upgraded internals. Its 2WD/RWD application is the key boundary when planning installation.

#2 · Best Standard 4L80E

2. JEGS 4L80E 500HP

• Weight: 194 lb
• Dimensions: 34.5 x 20 x 22 in

Best for: RWD LS Swap Builder.

Why it ranks #2: Lists 2000–2019 GM Gen III/IV LS fit, RWD configuration, 500 HP rating, 35-spline input, and lockup-converter compatibility.

A 500-hp rating paired with a 4L80E platform gives this JEGS remanufactured transmission a defined target for a Gen III/IV LS RWD build. Its 7-bolt bellhousing and stated 2000–2019 GM LS application help narrow the installation match before planning the rest of the drivetrain.

The aluminum case and OEM steel pan identify the supplied construction, while the 35-spline input and 2.48 first gear ratio provide concrete drivetrain details for a builder matching components and gearing. Lockup-converter compatibility also matters when selecting the converter. Rated to 500 hp, this unit suits a project within that stated ceiling; its 2WD/RWD designation makes it a candidate for rear-drive builds, not the listed 4WD truck use case.

Skip it if you need a stated rating above 500 hp; JEGS 4L80E HD 900HP is rated to 900 hp.

Choose this JEGS 4L80E for a Gen III/IV LS RWD build within its 500-hp rating, especially when lockup-converter compatibility matters. The stated 7-bolt bellhousing and 2WD/RWD application are key boundaries to match.

#3 · Best LS 4WD Match

3. JEGS 4L70E 4WD

• Weight: 145 lb
• Dimensions: 33.5 x 22.2 x 19 in

Best for: Late-Model LS 4WD Truck.

Why it ranks #3: Specifically fits 2009–2012 GM 4WD trucks with LS engines and is rated up to 500 HP and 450 ft.-lbs. of torque.

A 2009–2012 GM 4WD truck application makes this JEGS 4L70E a narrowly specified transmission option for late-model LS swaps. The 500-hp and 450-ft.-lb. ratings provide clear limits, while its 17-pin wiring harness connector supplies a key electrical detail for planning.

The 4WD, 4-speed automatic layout and stated 2009–2012 GM LS truck application help keep this transmission focused on the correct drivetrain category. JEGS rates it up to 500 hp and 450 ft.-lbs. of torque, making those figures practical screening limits for a build. Its 17-pin wiring harness connector is another installation detail to account for when arranging the electrical side. The listing also identifies it as dyno tested, without giving further test data.

Skip it if you have a 2007–2008 Chevy 2WD LS truck; JEGS GM 4L65E lists that vehicle application.

This 4L70E fits buyers planning a late-model GM LS 4WD truck build within 500 hp and 450 ft.-lbs. Confirm that the 17-pin connector and stated 2009–2012 application suit the project.

#4 · Best LS 2WD Truck Match

4. JEGS 4L65E 2WD

• Weight: 145 lb

Best for: 2007–08 Chevy 2WD Truck.

Why it ranks #4: Listed for 2007–2008 Chevy 2WD trucks with LS engines, with a 500 HP and 450 ft.-lbs. rating and 15-pin connector.

A specific 2007–2008 Chevy 2WD truck application sets this JEGS 4L65E apart for LS swaps: the listing identifies both the vehicle range and LS-series engine use. Its 500-hp and 450-ft.-lb. torque ratings give builders defined performance limits for evaluating a truck drivetrain.

The 4-speed automatic layout and 2WD truck application focus this transmission on a particular rear-drive installation rather than a broad universal swap. JEGS lists it for 2007–2008 Chevy trucks with LS-series engines, so that stated fit window helps screen candidates. Its rating reaches 500 hp and 450 ft.-lbs. of torque, and the 15-pin wiring harness connector is a concrete electrical detail to account for in the installation plan.

Skip it if you have a 2009–2012 LS 4WD truck; JEGS 4L70E Performance Transmission lists that application.

This 4L65E suits a builder replacing or planning a transmission for a 2007–2008 Chevy 2WD truck with an LS-series engine. Keep the stated model-year, drivetrain, 500-hp, and 450-ft.-lb. limits central to the match.

#5 · Best Included Fluid Package

5. Stellar 4L60E 4WD

• Weight: 190 lb

Best for: 4WD LS Truck or SUV.

Why it ranks #5: Rebuilt for 1998–2006 GM LS 4WD applications, rated to 450 HP, and includes 12 quarts of Lubegard synthetic ATF.

A 4WD-specific rebuilt 4L60E rated for up to 450 hp targets GM LS-powered trucks and SUVs from 1998–2006. Its upgraded Monster Sunshell, high-energy 3–4 clutches, and Transgo HD shift kit make this Stellar Automotive Group unit a detailed option for buyers planning a four-wheel-drive installation.

The 4WD application and 1998–2006 LS vehicle range focus this transmission on a defined group of truck and SUV swaps. Internal upgrades include a Monster Sunshell, high-energy 3–4 clutches, a high-energy 2–4 band, and Corvette servo, addressing named components rather than leaving the build specification vague. A Transgo HD shift kit is included, as are 12 quarts of Lubegard Complete Full Synthetic ATF, supporting a more complete installation workflow. Its stated ceiling is 450 hp.

Skip it if you need a stated rating above 450 hp; JEGS 4L80E HD is rated to 900 hp for 2WD/RWD LS applications.

Choose this rebuilt 4L60E for a 1998–2006 GM LS 4WD truck or SUV within the 450-hp limit. The included ATF and listed internal upgrades suit buyers seeking a transmission package, not a 2WD/RWD unit.

#6

6. Shift Rite 4L80E

• Weight: 300 lb

Best for: 2WD/RWD 4L80E Replacement.

Why it ranks #6: Offers a 4L80E identified for 2WD/RWD and several GM engine displacements, but the listing does not explicitly identify LS-generation fit.

A 1999–2009 2WD/RWD application and 4L80E identification give this Shift Rite transmission a defined role in the supplied listing. It names 5.7L, 6.0L, 6.5L, 7.4L, and 8.1L engines, giving builders a specific engine-range reference when screening a replacement.

The 2WD/RWD designation immediately helps separate this unit from 4WD transmission needs, while the 1999–2009 range frames its stated application. The listing also names 5.7L, 6.0L, 6.5L, 7.4L, and 8.1L engines, which gives buyers concrete engine sizes to compare with their build. It identifies the transmission as a 4L80E, but provides no horsepower rating or internal upgrade details, so those performance factors remain unspecified in the supplied information.

Skip it if you need a stated power ceiling or 4WD application; JEGS 4L70E lists a 500-hp rating for 2009–2012 LS 4WD trucks.

This Shift Rite 4L80E is for buyers whose project matches its listed 1999–2009, 2WD/RWD application and named engine sizes. Its supplied details do not establish a power rating or internal build specification.

#7

7. B&M 4L60E

• Weight: 140 lb

Best for: 4L60E LT-Motor Replacement.

Why it ranks #7: The title identifies a GM 4L60E transmission and the description says LS motor, but the supplied listing gives no power rating or detailed fitment.

The 4L60E designation and LT-motor description make this B&M transmission a focused candidate for a build centered on that named pairing. The supplied listing identifies it simply as a B&M 117308 transmission for a GM 4L60E LT motor, giving buyers a concise application starting point.

This listing provides a 4L60E transmission designation and identifies an LT motor, which can help a buyer screen for that particular drivetrain direction. The B&M brand and 117308 model number give the item a clear identity for parts planning. However, the supplied details do not state horsepower capacity, gear ratios, wiring connector, or a specific vehicle-year range, so those aspects cannot be assessed from the listing information alone.

Skip it if you need a stated LS-series application and power rating; JEGS GM 4L65E lists both for 2007–2008 Chevy 2WD trucks.

This B&M unit may suit buyers specifically evaluating a 4L60E for an LT-motor project. Its available listing details are sparse, so it is a poor choice when a stated power limit, connector, or vehicle-year application is essential.

#8

8. Speedmaster Universal V8

• Weight: 215 lb
• Dimensions: 40 x 28 x 28 in

Best for: Race-Only Universal V8 Build.

Why it ranks #8: Its rebuilt automatic has heavy-duty internals and a stated 400+ HP capability, but LS compatibility and street use are not established.

A heavy-duty internal package combining upgraded clutches, a hardened pump, and a performance shift kit gives this Speedmaster transmission its clearest purpose: V8 applications seeking a stated 400-plus-hp capacity. Its OEM bellhousing pattern offers a defined mounting reference, but the listing restricts use to racing.

Upgraded clutch packs and a hardened pump address internal durability, while the performance shift kit is specified to deliver firm shifts. Those features accompany the stated capacity for 400-plus-hp applications, giving a race-oriented V8 builder useful limits to consider. The OEM bellhousing pattern supports installation planning, but the input shaft spline count must match the application. The torque converter is sold separately, and the product is explicitly not for street use.

Skip it if you need a street transmission; JEGS 4L80E 500 HP is listed for GM LS RWD applications.

Consider this Speedmaster for a race-only V8 build where the 400-plus-hp capacity and OEM bellhousing pattern fit the plan. Verify the input spline count and source a separate torque converter before installation.

#9

9. Speedmaster TH700-R4

• Weight: 180 lb

Best for: Race-Oriented 700R-4 Build.

Why it ranks #9: This rebuilt overdrive transmission is identified as a GM TH700-R4, but the listing does not establish LS fitment or a power rating.

The Turbo 700R-4 identity makes this Speedmaster transmission a distinct overdrive choice for builders considering that named GM transmission family. Its listing marks it for racing applications only and not street use, an important boundary that immediately narrows its fit to race-focused projects.

The model designation PCE432.1028 and Turbo 700R-4 name provide a specific reference for a build organized around that transmission family. Speedmaster identifies the unit as a performance rebuilt overdrive transmission, which frames its intended role without supplying detailed ratios or power capacity. Its racing-only disclaimer is decisive for use planning: the listing says it is not for street use. Buyers should treat the supplied product images as the reference for included components, since the listing describes them as pictured.

Skip it if you need a street transmission; JEGS 4L80E 500 HP is listed for GM LS RWD applications.

This Speedmaster is for race-focused builders seeking a rebuilt Turbo 700R-4 overdrive unit. Its street-use exclusion is a firm boundary, and detailed power capacity or gear-ratio information is not provided in the listing.

#10

10. JEGS Powerglide 1200HP

• Weight: 126 lb
• Dimensions: 31 x 21.25 x 21.25 in

Best for: High-Power Powerglide Racing.

Why it ranks #10: The 1200 HP rating and SFI-approved case suit a specialized performance build, but the listing does not specify LS compatibility or vehicle fit.

A stated 1200-hp capacity and SFI-approved case put this JEGS Powerglide in a high-power, race-oriented category for LS swap planners. Its Prolite transbrake and 1.80 gears add specific hardware details that help buyers evaluate whether this transmission suits their intended setup.

The SFI-approved case and Prolite transbrake are prominent race-focused features, while the stated 1200-hp capacity sets a clear power target. Internally, the listing specifies an 8-clutch pack, high-flow pump, and new 9310 1.80 gears, giving builders concrete components to consider in the drivetrain plan. A deep pan is also included, and the turbo spline input shaft is an important interface detail for matching the transmission to the rest of the build.

Skip it if you want the listed 2.48 first gear; JEGS 4L80E 500 HP specifies that ratio for a GM LS RWD build.

Pick this JEGS Powerglide for a high-power build that can use its 1200-hp rating, SFI case, and transbrake. Its 1.80 gears and turbo spline input are important fit considerations before committing.
