I have a bunch of A50 and T14 TCM's, presumably from working trucks or these were tossed as cores. Each one appears to have an LMM (...459) cal file or LML (...880) cal file, but each one has a garbled or nonsensical VIN when I check the status.

1. Does anyone know if this is normal, or what may cause it?
2. Does it indicate another problem with the TCM?

Thanks for whatever contribution you can make. Times are TOUGH in the module world right now, especially A50/T14 modules. Thousands of unrepaired trucks are stacking up. I pulled these TCM's out of deep storage and trying to do something with them.
