GM T93 TCM Purchase - New Upgraded TCM

A brand-new GM T93 transmission computer, upgraded and ready to tune. Built for 2019 and newer GM vehicles with the 8-speed or 10-speed automatic, it arrives ready for custom tuning and diagnostics with HP Tuners.

You may not need this. A stock T93 can now be upgraded for free through the OBDII port. If your original TCM works, simply license it with 4 Universal Credits and tune it. Buy this only if you want a new TCM that's already upgraded.

Will it work on my vehicle?

Non-Global B vehicles only, including:

• 2020 and newer Chevrolet Camaro
• 2019-2022 Chevrolet Silverado 1500 and GMC Sierra 1500 (5.3L, 6.2L and 3.0L Duramax)
• 2020-2023 Chevrolet Silverado and GMC Sierra 2500HD/3500HD 6.6L Duramax (L5P)

Not sure which TCM you have? Look at the label on your current TCM, which is mounted on the transmission: it shows the TCM type (T87A or T93) and its service number. You can also connect your HP Tuners interface and read the vehicle in VCM Scanner, which shows the TCM in the vehicle information. Global B vehicles (2021 and newer Tahoe, Suburban, Yukon and Escalade, refreshed 2022 and newer Silverado and Sierra 1500) need the GM T93 TCM Service (Global B) instead, and 2019 and older vehicles with the T87A use the GM T87A TCM Purchase.

What else you'll need (sold separately)

• 4 Universal Credits to license the TCM.
• An HP Tuners interface such as the MPVI4.
• The latest VCM Suite BETA software (free from HP Tuners).
