T93 TCM Unlock Options
In order to start tuning your 2019+ GM vehicle's 8 or 10-speed transmission, its T93 TCM must be unlocked to accept tunes using VCM Suite. HP Tuners offers three options to choose from depending on your needs.
T93 TCM vehicle support includes, but is not limited to:
- 2020+ Chevrolet Camaro
- 2019-2022 Chevrolet Silverado 1500/GMC Sierra 1500 (5.3L/6.2L Gas/3.0L Duramax)
- 2020+ Chevrolet Silverado 2500HD/3500HD (6.6L L5P)
Only non-Global B vehicles
Note: T93 TCM support covers 8 and 10-speed-equipped 2020+ GM vehicles as well as some 2019+ GM vehicles.
Unlocked T93 TCM Purchase
Instead of sending in your original TCM for servicing, you can purchase a brand-new T93 TCM that is already unlocked and ready for tuning. This option is ideal for users who want their vehicle up and running as quickly as possible.
- New T93 TCM Purchase: $399.99
- T93 TCM License for tuning: (4) Universal Credits (sold separately)
- "Replace TCM" function in VCM Scanner is required.
Note: HP Tuners also offers support for the following GM controllers:
- GM E46 ECM found in 2020-2022 Chevrolet Silverado 1500/GMC Sierra 1500 3.0L Duramax (LM2)
- GM E90 ECM found in 2019-2021 Chevrolet Silverado & GMC Sierra, 5.3L & 6.2L V8
- GM E41 ECM (L5P) found in 2017+ Chevrolet Silverado and GMC Sierra 2500/3500 6.6L Duramax
Note: The T93 TCM is GM's replacement for the T87A TCM found in GM vehicles prior to 2020. If your vehicle is equipped with the T87A TCM, please see our T87A TCM service options.
Note: Universal Credits for licensing are not included in the cost of any unlock service or purchase. Credits must be purchased separately.
Service Notes
- The TCM you send in should already be programmed prior to the unlock service. If you choose to send in a spare TCM, you are responsible for providing us accurate vehicle information at the time you place your order and for later having the TCM programmed via a J2534 tool or OEM Dealer Diagnostic tool to your vehicle.
- After the TCM arrives at HP Tuners, an HP Tuners engineer will unlock the TCM so it can then be licensed, edited, and flashed with HP Tuners software. This is a one-time unlock that will not affect other operations of the TCM. The factory tools will still work for service and HP Tuners will then work for tuning.
- Once you receive the TCM back from unlock, re-install the TCM back into the vehicle, and then you may tune the TCM with HP Tuners' VCM Suite BETA by licensing the TCM for (4) Universal Credits (sold separately).
- If you're swapping to a new T93 TCM, the "Replace TCM" process is VCM Scanner is required. However, the IMMO relearn is NOT required.
- Once the upgrade is complete, users must license their TCM for (4) Universal Credits (sold separately) using the latest version of VCM Suite BETA and an MPV2, MPVI2+, or MPVI3 interface.
