The P0605 indicates that the Transmission Control Module (TCM) is faulty.
Replace the Transmission Control Module. The fault is for a internal Transmission Control Module failure. There is nothing external that can cause this code.

installed new tcm from dodge dealer and set same code. then tried tcm for another 2001 intrepid from my used car lot same thing.
Expert:  Amedee replied 7 years ago.
Then a power or a ground to the tcm is the problem. Just be sure that no other modules are shorting out causing the tcm to go down or off line.

Hello and welcome to Just Answer. My name is Denny; now let me see if I can help you with Dodge question

P0605 is for internal PCM failure, not TCM.

You need to replace the PCM. You say you already did, but it must be a new one from Chrysler, or you will get this code from a used or rebuilt unit..
