    The P0700 just means that there is a code stored in the transmission control module (TCM), and the P0605 is the one actually stored in the TCM module. P0605 is an internal failure in the TCM module. It has failed one of its own self tests in its ROM memory and needs to be replaced. Once the TCM module is replaced, in some cases it has to be calibrated with a dealer scan tool before the speedometer will work correctly. Good luck and let me know if you have any other questions.

    Thanks for the answer. I can't find any reference to the TCM in my Chilton manual, or on any how-to website. Where is it and what does it take to replace it?

    The module is located on the front L/H side of the engine compartment. It has one connector on the front side of it. To get access you must take off the L/H head light housing. With that removed you can get a 5/16 socket on the connector. There is hole cut for the socket. You should be able to remove it then. Putting it back on, you will have to remove the back side of the connector. There are 4 tabs, just pull them out two at a time ( each side) and pull on the back side of the connector.
