How to remove the bolts on a 2006 Suzuki Firenza transmission converter

I can't find that code anywhere online. Guess it's time to call a Suzzuki maintenance dept. See if they will give you some idea of what's going on. I do see that error code listed for other cars. Most seem to be transmission fluid level indicators. Auto Zone may be able to tell you more or at least reset the codes. Check the fluid and maybe change it, then have them reset it and see if it returns.
