GM 10L80 / 10L90 transmission tune
2017+ Silverado, Sierra, Tahoe, Yukon, Escalade; Camaro ZL1
What we change on this platform
Skip-shifts reduced with the gear spacing kept sequential, firmer upshifts, converter locked in the gears you actually cruise in, and sport-mode scheduling in normal mode if you want it.
What your truck needs first
By model year, from HP Tuners' current support list. This is the owner's side of the job — interface, licensing credits, and any one-time module upgrade.
| Model years | Module | Status | Interface | Credits |
|---|---|---|---|---|
| 2017–2018 | T87A TCM | Ready to tune No unlock service needed since Nov 2025. | MPVI2 or newer | 4 |
| 2019–2024 (Global A) | T93 TCM | Direct OBDII upgrade first One-time Direct OBDII upgrade done in VCM Suite at the truck. No shipping. | MPVI3 or MPVI4 | 4 |
| 2021+ Global B models | T93 TCM (Global B) | Send-in service first Send-in Global B service for the TCM; MPVI4 only. Engine-side tuning on these trucks needs a separate ECM service ($999.99) — not required for a transmission-only tune. | MPVI4 | 4 |
What you send us
