Need a GM ignition key relearn procedure

Macon GA

Description

Based on the the background below, I was told I needed a new TCM/transmission (powertrain) control module.To àvoid involving a dealer, I found a company on the internet that manufactures TCMs specific to your vehicle. To do that, they needed the vehicle vin and the TCM part number (located on the part itself). I had the old control module removed, located the needed part number, and ordered the new module. The new module arrived and was installed. While I was off at AutoZone having my battery recharged, my mobile mechanic fled, apparently not wanting to perform the GM key relearn procedure despite the clear instructions that came with the new module. So, I am now looking for a new mobile mechanic to perform this key relearn procedure. If you send me an email, I can email you the instructions that came with the new module. BACKGROUND Gears had been slipping, RPMs racing with little or no motion, dash light indicating automatic transmission fluid overheating. Garage diagnosis reads "TCM/ transmission internal failure, pressure control solenoid/TCM failure." I am a relatively poor uber Lyft driver. Texts (preferred), emails; NO CALLS PLEASE!. Thanks in advance for any help you can provide! - Andrew
