When this code is triggered, it means that there is a communication error or malfunction within the control module, which can lead to significant performance issues and potential safety concerns.

Tech Notes for P0605 Chrysler
P0605 Indicates that the programming for your transmission functions has become corrupted. In your 2008 Jeep, you should have one module (PCM) that controls the engine & transmission, and most likely needs to be replaced. If you have a individual TCM, it will be a little black box (a bit bigger then a credit card) under your dash on the DRIVER SIDE.
Note to some readers: If you are getting this code on an older vehicle (before 2003), especially Chrysler products, and you are getting this Code your TCM needs to be replaced. Flashing the TCM will not resolve this issue (maybe for 2 weeks at most). I say this because the info provided in the description of the Code is geared towards newer vehicles that use a PCM (or ECM as commonly referred to still).
