GM T93 TCM Service (Global B)

Prepare your GM T93 TCM-Equipped Vehicle for Tuning

In order to start tuning your GM (Global B) vehicle’s T93 TCM (10-speed transmission), it must be upgraded to accept tunes using VCM Suite (BETA) software. This controller can be found in the following vehicles:

Note: HP Tuners also supports the GM Global B E99 ECM found in these T93 TCM-equipped supported vehicles. See our GM E99 ECM Service (Global B) here.

This one-time service upgrades your original T93 TCM that’s returning to the same vehicle it came from. Our expert team will perform the TCM upgrade without pre-programming it with a VIN. Users must physically remove the T93 TCM from their vehicle and ship it to HP Tuners’ headquarters for servicing. Once upgraded, users have full access to calibrate, log, and scan via the OBDII port.

Everything you need to tune your T93 TCM vehicle with HP Tuners:

• This one-time, send-in GM T93 TCM Service (Global B) (upgrade service).
• Download the latest version of VCM Suite BETA for free here.
• Once upgraded, purchase (4) Universal Credits to license your T93 TCM.
• GM Global B vehicle support is only compatible with our MPVI3 and MPVI4 interface.

Note: Universal Credits for licensing are not included in the cost of any upgrade service or purchase. Credits must be purchased separately.
