    Pulled TCU and fairly easy to do with only 2 screws holding the kick plate, pulling up the plastic sill plate and prying up the carpet enough to pull the plastic TCU box. Take the plastic cover off and pull 2 more screws to get the aluminum TCU cover free. Connector is a cam over lock that rotates off. Now when I took the plastic cover off, the top of my TCU cover fell off. Apparently, it has been apart before as the tabs are all broken off. Can anyone look at the TCU board and tell me if it is stock or has a chip? The chip in the upper left has a label on it and doesn't appear to be a factory solder job. I pulled the TCU because of shift problems (coming out of gear under WOT).

    905084, I don't know if you're chipped or not -- hopefully someone else will recognize that label -- but could you do me a favor while you have the TCU out? Assuming you have an meter that can measure resistance, otherwise never mind.

    I am curious to know what the resistance is between the two CAN bus pins on the TCU. This can be done with the TCU on the bench and unpowered. The two pins are 85 and 86, which are most likely labeled on the connector with very small numbers.

    Sorry kday, just chucked it back in to take for a spin and see if the contact cleaning helps my shifting problems. I'm sure it will be out sometime i the near future though. What do those pins do? Don't want to ohm out something a fry a chip, but happy to help if I can.
