    17 Camaro A8 unlocked TCM codes

    I have a 17 Camaro that I ordered an unlocked tcm and after following all the directions for the program and install it throws codes, almost stalls when it goes into gear and the gear indicator on the dash keeps flashing in drive or reverse. Anyone seen this issue? The codes are...

    0x7E8: P0700 - Transmission Control System (MIL Request) (Pending, Current)
    0x7EA: P16F0 (Pending, Current)

    Did you order a brand new TCM? If so, it has to be programmed first.
