Thanks for the answer. You are very kind.
According to your answer below, I should try and find if something's wrong with the Torque Management Serial Line.
Question: Is there a way to identify this line? Color or something?
Thanks again.

Your answer:
the tranny control module (TCM) is behind the left side of dash, above kick panel.

code 37 : Torque Management Serial Line Faulty

Check wiring to the PCM and TCM. if OK suspect faulty TCM.
