Is there a gm t87a tcm clone / unlock shop in Detroit I should use instead?

Does Michigan vehicle inspection or emissions testing affect this service?
Michigan has no statewide periodic vehicle safety or emissions inspection program. Our service is bench module programming only — you remain responsible for your vehicle's compliance with all Michigan and federal requirements.
Is this on-car or bench?
Bench. You ship the module (and donor for a clone); we do the work and ship it back. There is no OBD/SPS session involved on our end — that is exactly what this service exists to avoid.
Clone or unlock — which do I need?
Clone if you are replacing a failed T87A or moving one into a swap and want your transmission's learned adaptations to carry over plug-and-play. Unlock if the module is fine and you want a tuner to be able to write calibrations to it. Tell us which at order time; they are different bench operations.
