alright, i have an 06 r/t and sometimes when i go to start it, the abs, esp, check engine, and a few other lights come on, then when i try to drive it wont shift out of 2nd gear and wont go above like 4k rpm. It will shift into park, reverse, neutral, etc all really hard. The only way to fix it is to reprogram the vehicle with the superchip flashpaq, or let it sit for a while. this problem has been getting more frequent and is starting to scare me. Could it be the superchip, cause i read online it has something to do with the CAN something? Please help

Mine does this when I throw my Codes

I have not yet fixed whatever issue is causign my u1121,u0121,p0645, and p0681 codes.

Communication with the tranmission has ceased. because of the codes thrown.... it will go in gear but not shift or rev anywhere near a shift point.
so far thats what i have learned.
