Posted: Sun May 30, 2004 4:19 pm Post subject: does anyone know what this code means?
I have a 2002 TLS, and I took it to autozone to get the code pulled. It came back as P0740 TCC Circuit Malfunction. I looked it up online, and all I came up with was that TCC stands for Torque Converter Clutch. Anyone know what this means? anyone know how to fix it? do I need to take it to the dealer, because my warranty just ran out 3k miles ago. Any help? thanks!
Possible cause for the DTC code: faulty lock-up control system!
A little background info courtesy of Honda: "By adopting the clutch pressure direct control system and a new logic control system, precision of the transmission control has been drastically improved and optimized. Also, the lock-up control system for a wide range of transmissions, from 2nd gear to 5th gear, the highly efficient and ultra thin torque converter, and the low friction clutch all contribute to higher fuel economy."
Your problem could come from a leak in one of your hydraulic pressure lines, or lack of pressure to any of your clutches. If not that, you may need to replace your lock-up control solenoid valve assembly, torque converter, or if you are really unlucky your entire tranny.
As a general rule of thumb if it deals with your transmission take it to a pro. Internal tranny problems are the most complicated repairs. Unless you feel up to the job _________________ If you feel like you're in control, you're not going fast enough. ~ Mario Andretti
I don't mean to bring a topic up from the dead. But I am having this same code. My mechanic has swaped the solinoids. And swapped the transmission. Everything works fine it just throws this code after about 50 sec of driving any idea's?
If you have access to an ECU you know to be good, try swapping it out. If the ECU is messed up it could just start throwing out random codes at random times. That is the only thing i could think of if you already replaced the entire tranny. _________________ If you feel like you're in control, you're not going fast enough. ~ Mario Andretti
