I have been getting the code p0740 it says something about the torque converter clutch circuit. it doesn't seem to be going into over drive. dose anyone have any suggestions I can try.


On some cars, there is a TCC solenoid in the transmission which can be replaced by removing the bottom pan. In some cars this solenoid can't be accessed without major disassembly.

P0740 T Converter Clutch Circuit Malfunction


The transmission fluid could be in need of a change, certain parts in the transmission depend upon clean fluid to move properly, this could cause the pressure sensor to fail and engage the torque converter to lock up at the right time. Timing is counted with the computer and it will flash lights when there is a problem.

I have a 20001 Odyssey with 70,000. The check engine light and TCS light both came on. The TCS light has since gone out but the check engine remains. I went to an auto parts store and their computer came...


unfortunately it is. Contact your local dealership to see if it may still be covered under a warranty or not.

Customer Concern: The check engine light is on with the trouble code P0740 present. Tests/Procedures: 1. Test drive the vehicle and watch the tachometer. See if the automatic transmission locks up. If unable to see the RPM change, and the Engine Control Module (ECM) is turning on the lockup solenoids, then the problem has to be internal to the transmission. The transmission has an extended warranty from Honda for 7 years or 100,000 miles. Potential Causes: Automatic Transmission
Lock-Up Solenoid
Torque Converter
Tech Tips: TSB #02-062 Diagnostic Codes: P0740

Honda torque converter clutch solenoid circuit


P0740 is a Torque Converter Clutch Circuit Malfunction, you will need to have just this circuit tested, it is mostly just a defective Torque converter clutch solenoid in the trans or a defective connection to the trans, u do not need another overhaul.

2000 Honda Accord Check Engine light on p0740


YOU HAVE A TORQUE CONVERTER PROBLEM. TORQUE CONVERTER CONTROL CIRCUIT MALFUNCTION CODES CAN COME FROM ELECTRICLE TO INTERNAL MALFUNCTION. IF YOU START EXPERIENCING A HARD SHIFT OR FREE SPIN TO HARD SHIFT DON'T BE SURPRISED. TRY CHANGING FLUID. THIS MAY HELP. HONDA WOULD HAVE REPLACED TRANS IF UNDER 105 k FOR FREE. IF YOU HAVE TO REPLACE TRANS. BUY ONE FROM HONDA, 3 YR WARRANTY AND AS CHEAP AS A REBUILT TRANS. HAVE A QUALIFIED PERSON INSTALL, YOU WILL SAVE ABOUT $500 DOING IT THIS WAY. GOOD LUCK
