GM T93 TCM Purchase

Upgrade your GM T93-Equipped Transmission for Tuning!

In order to start tuning your 2019+ GM vehicle’s 8 or 10-speed transmission, its T93 TCM must be upgraded to accept tunes using VCM Suite. You can now uprade directly via the OBDII port if you are using the stock GM T93 TCM. However, if you want to purchase a brand-new, already upgraded GM T93 TCM, you’re in the right place!

T93 TCM vehicle support includes, but is not limited to: (Only non-Global B vehicles)

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

Note: T93 TCM support covers 8 and 10-speed-equipped 2020+ GM vehicles as well as some 2019+ GM vehicles (non-Global B). To confirm if your 2019+ GM vehicle has the T93 TCM requiring this upgrade service for tuning, please contact [email protected].
