My 2006 Lexus IS250 has been displaying VSC, TRC and engine check light on for about 2 months now. I have read the discussion about the same problem from other members here on this forum. OBD check accuses the famous Shift solenoid C as the main culprit. the local dealer does not seem to settle for anything less than a new transmission set altogether but i am not prepared to spend that much. Can someone please help me with an online supplier of the solenoid C so i can have it changed. Thank you.
