DTC P0740 - Torque Converter Clutch Circuit Malfunction


my 98 honda accord has the check engin light on n  - 2_23_2012_5_15_10_pm.jpg


It sounds like you need new solenoids in valve body you have a open circuit in the T/C clutch solenoid valve in valve body, I would replace the solenoids to fix your problem and inspect all connection to transmission valve body.

The valve body will need to be removed to get the valves replaced This can be a little hard if you have not done this before it comes with harness and solenoid pack together.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

I am sorry to bum you guys out, but this usually means the piston in the torque converter is bad. The converter needs to be replaced along with a transmission flush.

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

Horsecrap...go to an independent transmission dealer after you call the extended warranty folks and complain!
I can count the number of Honda transmissions that go bad before 300,000 miles on one hand.
Good Luck

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.

98 honda accord how to clear check engine light car is fixed


You need an OBD-II scantool to reset the Check Engine light. Places like Autozone will read your codes for you but most will not reset the Check Engine light because of liability issues. You need to either purchase a code reader with reset capability or find someone who has one to do it for you.

P0740 honda odyssey


P0740 Honda - Transmission Lock-Up Control System Fault Possible causes
- Low transmission fluid level
- Dirty transmission fluid
- Faulty torque converter clutch solenoid valve
- Torque converter clutch solenoid valve harness is open or shorted
- Torque converter clutch solenoid valve circuit poor electrical connection

Tech notes
On some Honda vehicles the P0740 code may be set by an overheating torque converter problem which is caused by an insufficient flow to the torque converter release circuit.

P0740 Honda Description
The torque converter clutch solenoid valve is activated, with the gear in D4, by the Transmission Control Module (TCM) in response to signals sent from the vehicle speed and the Engine Control Module (ECM). Lock-up piston operation will then be controlled. When the torque converter clutch solenoid valve is activated, the torque converter lockup clutch will engage creating a 1 to 1 RPM ratio between the transmission input shaft and the rotational speed of the torque converter.
Lock-up operation, however, is prohibited when A/T fluid temperature is too low.
When the accelerator pedal is depressed (less than 2/8) in lock-up condition, the engine speed should not change abruptly. If there is a big jump in engine speed, there is no lock-up.

There could be a million different causes. I recommend taking to Reillys, Autozone or another of the myriad of places that will code read your computer to find the 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
