Hello,

Just say thank you for everything, for help.
In hope that draws its help another person

I finally found the lead that was cut,
was the leading No. 16 out of PCM that went EATX relay internal filaments was cut inside and outside the sheath was well full, not possible to see that the file is divided.
After repair of the cable and any other cable removed,
Blanked defects with the suitcase Altar Elite MD802,
speeds normally spend very soft, no default

No disrespect to Chrysler engineer beams are very poorly done inside
all queues are folded ised,
normal they cut withdrawn when the transmission or engine vibration or ground

thank you again
Happy New Year 2015 to all of you and your family in this forum and out
best regards
