Bricked EGS52 ?

Something happened last night during a flash that seemed to brick my TCM / EGS52. 2006 Jeep Commander 3.7

Internal ROM error faults stored. Immediate transmission overtemp errors on startup, shift selector doesnt work, transmission limp mode etc etc. I tried battery reset. Tried re uploading my factory tune. No luck. The write process completes without any errors. Help ticket already sent.... but any ideas or am I replacing a module?

HP support said flash back to stock with Dodge Scan tool. That would have meant a trip to dealership in my case.

I purchased a new reman TCM and installed as that was the cheaper and easier option. Errors all gone now at this point.


HOWEVER, when i read out the new module all the TCM functions were blank in VCM Editor like the tables didnt read. I repeated the read and now they are there and populated. Followed up with HP support, but something is screwy when reading and writing these. Use caution
