It's possible that the connector board in the trans is bad because of a overly "helpful" mechanic (see above mentioned post) and the TCM is still good so installing a new TCM will only result in damage to the new TCM and you will be back at square one.
Fortunately I had access to another SRT and was able to verify it was bad by swapping it.
Easy test is to install your TCM in a another SRT. If you don't have any near you then you can send me yours and I'll check it on my car.
If TCM is good I would inspect the trans connector board (PITA/messy) next. That would be the part the mechanic messed up.
Man thats so crazy Ive had the same problem for more then a year coming and going with no mechanics having any idea what was up where you able to replace the tcm yourself or did you have to take it in to a tranny shop
