Problems reading the tcm on DSL 04 LLY

[ls1pr]

I have Duramax 2004 E60 LLY, reading the ECM and TCM, the app reads the PCM but when goes to the TCM does not read nothing and jumps to the save the file with out the TCM readed.

Can i just select read the ECM? I'm afraid to brick the TCM..

Any ideas?

Thanks

i had problems reading in "high speed", it did fine once i unchecked the two boxes. id give that a try. I also had the same high speed problem on my 2005 ls truck.

the 05 lly i tuned had to have 5 fuses pulled from under the hood. radio amp, info, tbc batt, tbc ign 1, and radio. pull those fuses and see how that goes. i think theres a thread in the stickies about the 05 llys but it may apply to the 04s as well
