T93 TCM Upgrade Options

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. 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 (non-Global B). To confirm if your 2019+ GM vehicle has the T93 TCM requiring this upgrade service for tuning, please contact sales@hptuners.com.

T93 TCM Upgrade Only Service

This option upgrades your original T93 TCM that is returning to the same vehicle it came from. Our expert team will perform the TCM upgrade without pre-programming it with a VIN.

  • T93 TCM Upgrade Only Service: $199.99
  • T93 TCM License for tuning: (4) Universal Credits (sold separately)

Note: If you are removing the T93 TCM from your vehicle and plan to reinstall it in a different vehicle, this is NOT the service for you. Please select “Unlock & Program Service” instead.

T93 TCM Upgrade & Program Service

If you want to upgrade a T93 TCM (new or old) for a different vehicle (not the original vehicle it came from), this Upgrade & Program service will do just that. Our team will upgrade and pre-program the TCM for your specific VIN, so it’s plug-and-play—no need for the GM factory tool. When adding this service to your cart, you MUST enter the VIN of the vehicle you plan to install the TCM in.

  • T93 TCM Upgrade & Program Service: $299.99
  • T93 TCM License for tuning: (4) Universal Credits (sold separately)
  • “Replace TCM” function in VCM Scanner is required. See instructions here.

Note: If you are removing the T93 TCM from your vehicle and plan to reinstall it in the same vehicle, you do not require this service. Please select the “Unlock Only Service” instead.

Upgraded T93 TCM Purchase

Instead of sending in your original TCM for servicing, you can purchase a brand-new T93 TCM that is already upgraded 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. See instructions here.

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 upgrade service or purchase. Credits must be purchased separately.



  • These GM T93 TCM Services do not apply to Global B vehicles. We do not accept T93 TCMs with Serv #24049788 as this means it’s a Global B vehicle. Please check your T93 TCM prior to purchasing any of these services to confirm your T93 TCM is accepted. Please see this photo to locate the Serv# on your TCM to verify.
  • The TCM you send in should already be programmed prior to the upgrade 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 upgrade the TCM so it can then be licensed, edited, and flashed with HP Tuners software. This is a one-time upgrade 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 upgrade, 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. Find the instructions here. 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.

Should you have any further questions, please email sales@hptuners.com. If you experience any issues with licensing, submit a support ticket.

If you select the Purchase option, these steps do not apply to you.

Step 1: Once you’ve confirmed your vehicle’s support (2019+ GM vehicles equipped with 8 and 10-speed transmissions and T93 TCM), select what service best fits your needs.

Step 2: After placing your order with the necessary information, see the “Shipping” tab for a shipping form and address. Fill out and print this form to place in your shipping box. You will also receive an email immediately after placing your order with this shipping form and address.

Step 3: If you purchased the Upgrade or Upgrade and Program service, remove the TCM from your vehicle and safely package it. If you purchased the Upgrade and Program service, make sure you first perform the “Replace TCM” function. This is not required for the Unlock service as long as the TCM is returning to the same vehicle it came from. Then, package your TCM safely with the shipping form.

Step 4: Write your order number on the outside of the shipping box.

Step 5: Ship your TCM to HP Tuners using any carrier you prefer. The shipping address can be found on this page and in the email discussed in step 2. Shipping costs are the responsibility of the customer.

Step 6: HP Tuners will upgrade and/or program your TCM for tuning and diagnostics. Then, we’ll ship it back to you.

Step 7: Once you receive your upgraded TCM, install it back into your vehicle. If you selected the Unlock and Program option, you must perform the “Replace TCM” function again. Then, license the unlocked T93 TCM for (4) Universal Credits (sold separately) and start tuning with your MPVI2 or newer generation device and the latest version of VCM Suite BETA.
