GM 6L80E Stage 1 Performance Transmission
2WD & 4WD Applications
3-Year Warranty* • Unlimited Mileage
Street Performance Build • Super Duty Billet Cover Torque Converter Included
The Step Above Our Stock 6L80E
The Transmission Depot Stage 1 6L80E is our street performance build
for daily-driven GM cars, trucks and SUVs that need more than a
factory-style replacement without turning the transmission into an
aggressive race build.
Every Stage 1 is completely torn down, cleaned, inspected and built
in-house. We address the known 6L80E clutch, converter, pump and
hydraulic wear areas, build the clutch assemblies with
high-energy clutches and steels, and pair the transmission
with a Super Duty billet cover torque converter at stock stall speed.

Super Duty Billet Cover Torque Converter
Stage 1 includes our Super Duty billet cover torque converter.
The billet cover provides a stronger foundation in one of the most
critical areas of the 6L80E while retaining a
stock stall speed.
Keeping the factory-style stall characteristics maintains predictable
engagement and daily-driver behavior. This is a street transmission
and converter package built to work together — not a high-stall
converter added simply because the transmission is labeled performance.
High-Energy Clutches Still Need Proper Apply Pressure
A stronger friction material does not correct a worn hydraulic circuit.
Wear in the 6L80E pressure regulator, boost, TCC and related circuits
can reduce clutch apply pressure, create converter clutch concerns
and contribute to premature clutch failure.
Stage 1 addresses the pump and valve body along with the clutch packs.
Proper hydraulic operation and clutch clearance are part of the build,
not something we try to compensate for with friction material alone.
OE Hard Parts — Inspected, Measured and Reused When They Meet Spec
Drums, shafts, planetary assemblies, hubs, stator support and one-way
clutch are cleaned and inspected for wear or damage. Serviceable OE
hard parts are retained when they meet our build requirements.
Anything that does not meet specification is replaced.
What Stage 1 Is Built For
• Daily-driven GM cars, trucks and SUVs
• Stock and mildly modified engine combinations
• Common bolt-on modifications
• Street-driven LS applications
• Stock and mildly modified 5.3L, 6.0L and 6.2L combinations
• Customers wanting a step above our stock replacement 6L80E
Vehicle weight, engine torque, tire size, tuning, towing requirements
and intended use all matter when choosing the correct 6L80E build.
Stock vs. Stage 1
Stock 6L80E
Remanufactured factory-style replacement for stock-powered
and standard-use applications.
Stage 1 6L80E
High-energy clutches and steels, Super Duty billet cover
torque converter at stock stall, and a street-performance
build for applications needing more than our stock replacement.
6L80E Fitment Must Be Verified
GM used the 6L80E across numerous cars, trucks and SUVs with important
differences by year, engine, drivetrain, output configuration and
electronic calibration. Have your
VIN, year, make, model, engine size and 2WD/4WD configuration
available when ordering.
TECHM Electronics Package — Selection Required
Every Stage 1 6L80E order requires a TECHM electronics selection.
Fully Programmed TECHM by VIN — +$399
Provide your VIN at checkout and we will supply the TECHM programmed
to your vehicle before shipment. This eliminates the need for full
dealer VIN programming after installation. Required setup, reset
or relearn procedures must still be completed when applicable.
Blank TECHM — Included in Price
Decline the pre-programmed option and the transmission will be supplied
with a blank TECHM at no additional charge. The TECHM must be programmed
to the vehicle VIN after installation by a GM dealer or qualified
repair facility using proper GM-compatible programming equipment.
VIN MUST BE PROVIDED AT CHECKOUT WHEN SELECTING THE
FULLY PROGRAMMED TECHM OPTION.
3-Year Warranty / Unlimited Mileage*
Installation, activation and warranty requirements apply.
See complete warranty terms for coverage details.
