Do you accept gm t87a tcm clone / unlock modules from Tennessee?

Is there a gm t87a tcm clone / unlock shop in Nashville I should use instead?
Most Nashville shops don't keep the bench equipment for gm t87a tcm clone / unlock — they'd forward the module to a specialist anyway, which adds a markup and a middleman. Going direct to us is usually faster and cheaper. Cross-region northeast — about 2 days each way.
Does Tennessee vehicle inspection or emissions testing affect this service?
Tennessee discontinued its county emissions testing programs and has no statewide periodic safety inspection. Our service is bench module programming only — you remain responsible for your vehicle's compliance with all Tennessee and federal requirements.
Will a clone need a dealer relearn?
No — that is the point of cloning. The donor carries your T87A's identity and adaptations, so the vehicle sees the same module and no SPS session is required. A raw used T87A would need dealer programming; a clone does not.
Which transmissions does this cover?
The 8L45/8L90 and 10L80/10L90 automatics with the T87A controller across ~2015-2021 Silverado/Sierra, Camaro, Corvette C7, Escalade and more (Global A era). The newer Global B trucks use the T93, which is a different locked platform we do not cover. Send the part number off your module and we confirm before you ship.
