Do I need programming after install?

Yes. Perform a full reprogram/relearn. 6L80E/6L90E typically require TEHCM/strategy updates and an adaptive drive cycle. Verify connectors and sensors match your application.

Chevy/GMC Transmissions

Q: Which tier fits my Chevy/GM build?

Stock/commuter → RoadReady. Daily/towing with a mild tune → StreetMonster. Street/track or added load from tires/gearing → SportMonster. Competition or 700+ HP → TrackMonster.

Programming & electronics—anything special for GM?

Plan for a full reprogram/relearn after install. 6L80E/6L90E typically need TEHCM/strategy updates and an adaptive drive cycle. Confirm connectors/sensors by year and application.

What should I do during install?

Flush/replace the cooler & lines, use the correct fluid (e.g., DEXRON-VI where specified), verify output/driveshaft compatibility, and complete the adaptive learn. Skipping these steps risks contamination and may void coverage.
