Is there a gm t87a tcm clone / unlock shop in Manchester I should use instead?
Most Manchester 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-country northeast — about 3 days each way.
Does New Hampshire vehicle inspection or emissions testing affect this service?
New Hampshire requires an annual safety inspection statewide, with OBD-II emissions testing for newer model years. Our service is bench module programming only — you remain responsible for your vehicle's compliance with all New Hampshire 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.
