The code is for the 3-2 shift solenoid. The solenoid resistance spec is 20-32 ohms. I attached a pic to help locate it.

If the only code is the one listed above then there is only 1 wire to worry about. The power for the solenoid is the same wire for all so if one works then power is good. The control wire from pin 34 at the pcm is all you would have to check.
