The 10L80 is a GM 10-speed automatic used in late-model Chevy/GMC trucks, SUVs, and performance platforms. Verify fitment by year, drivetrain (2WD/4WD), and your existing transmission model before ordering.
Yes—this RoadReady package includes a remanufactured torque converter.
After install, it’s normal to perform the appropriate programming and an adaptive learn/relearn procedure so shift timing and converter lockup settle in correctly.
Use the OEM-specified 10-speed transmission fluid for your application and follow the correct level-check procedure for your year/model.
Confirm strong cooler return flow, flush/replace contaminated lines, and keep temps under control—especially for towing or hot-weather use.
*Fitment and capacity depend on vehicle configuration, tuning, tires, and use. When in doubt, call Monster tech support before ordering.

The GM 10L80 (also commonly searched as 10L80E) is a modern 10-speed automatic built for strong acceleration and efficient cruising. With closer gear spacing than older 6-speeds, it helps keep your engine in the powerband while reducing RPM on the highway—great for daily driving, towing, and performance-oriented trucks and SUVs.
Many 10L80 shoppers land here after feeling delayed engagement, hard 1–2/2–3 shifts, gear hunting, or converter shudder. The fix isn’t just “a transmission”— it’s the full system: healthy hydraulics, correct converter behavior, clean fluid, proper cooler flow, and correct calibration.
The 10L80 relies on refined lockup control for drivability and heat management. A matched OE-style converter helps maintain factory-smooth apply feel and reduces unnecessary slip—especially under load. That’s why Monster’s RoadReady package includes a fully remanufactured torque converter.
Heat is the enemy of clutch life. If you tow, run larger tires, drive in high ambient temps, or do spirited driving, prioritize cooler return flow verification and consider a low-restriction auxiliary cooler. Clean, correct OEM-spec fluid and stable temps are the easiest “mods” to extend 10L80 life.
After installing a fresh 10L80, it’s normal to complete the appropriate programming and then an adaptive learn/relearn drive cycle. This helps the transmission dial in shift timing, pressure control, and converter lockup behavior—protecting the new clutches and improving shift quality.
Both are GM 10-speeds, but they’re not interchangeable. Fitment depends on application, case/output configuration, and calibration. Always verify the exact transmission model before ordering.
Yes—Monster’s RoadReady 10L80 package includes a remanufactured converter.
Use the OEM-specified 10-speed transmission fluid for your year/model and follow the correct level-check procedure.
If you tow, drive in heat, run bigger tires, or want maximum longevity—yes. Stable temps and strong return flow are key.
In many installs, yes—follow the correct programming and relearn steps for your vehicle so shift quality and converter lockup settle in correctly.
