The code is related to the torque converter clutch. It is stuck in the off position. This could be a wiring issue, low line pressure, or the TCC clutch solenoid.
I attached directions below related to the code. The attachments include a description of the code and how to diagnose the problem.
Let me know if this helps or if you have other questions.
Take care,
Joe
