Description
Take full control of the GM 6L80 / 6L80E 6-speed automatic behind your LS or LT V8. With HP Tuners, N2 Speed delivers a custom transmission calibration that transforms shift quality, power delivery and drivability — whether you are stock, cammed, boosted or towing.
We recalibrate shift points, shift firmness and shift time, line pressure, torque converter lockup and torque management so the trans holds gear where you want it, shifts crisply under load and stops slipping through the factory soft-shift strategy. Every tune is built for your combination, not pulled off a shelf.
Key Benefits:
- Optimized shift points for performance & drivability
- Firmer, faster shifts with corrected line pressure
- Torque management reduction for stronger power delivery
- Torque converter lockup tuning for cruise and WOT
- Improved towing and hauling performance
- Calibrated using HP Tuners for precision and reliability
Fits: GM vehicles equipped with the 6L80 / 6L80E (and 6L90) 6-speed automatic — Camaro, Corvette, Silverado, Sierra, Tahoe, Suburban, Yukon, Escalade, CTS-V and more.
What you need: An HP Tuners MPVI2, MPVI3, MPVI4 or RTD device. The 6L80 / 6L90 TCM requires no additional HP Tuners credits — it is licensed with the ECM, so there is nothing extra to buy. GM ECMs are not locked, so no unlock service is required.
Once purchased we will send instructions on how to proceed. Any questions please email us sales@n2speed.com
HP Tuners RTD / TDN Network: We can also work with the HP Tuners RTD interface and the TDN (Tuner Dealer Network) — if you already run an RTD or are set up on TDN, we can deliver and revise your calibration through the network instead of emailing files. Email your VIN and setup to sales@n2speed.com and we will get you linked up.
