PLEASE READ ENTIRE DESCRIPTION TO UNDERSTAND ALL OPTIONS
This is a service for you to send your T87A controller to us to be unlocked as well as programmed to your vehicle. This allows you to take a unit that hasn't been programmed to your specific vehicle yet, and have us program it to be repurposed for your application as well as unlocked for tuning. After unlocked your transmission controller will be able to be tuned with HP Tuners. THIS DOES NOT INCLUDE THE CONTROLLER ITSELF. If you want us to supply you with a TCM you want this service here: T87A Programmed and Unlocked for HP Tuners
This service option will upgrade your T87A TCM to enable tuning. Send us your TCM and we’ll send it back to you fully upgraded for tuning. Make sure to include your VIN when checking out. This service takes 1-2 business days to complete.
Note: If you only need the unlock service and don't need your controller repurposed for your vehicle (meaning the controller you wish to send is the original from your vehicle) Then you want to use this service here: HP Tuners T87A Unlock Service
