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.

0700 codes after replacing speed sensors


Hi there:DTC P0700 is a generic warning code that advice about a transmission fault specific code stored there. In this case, your addicional specifi code is P0740.
DTC P0740 - Torque Converter Clutch control circuit (A/T Torque Converter Clutch - No RPM Drop At Lockup)

This can be caused from as little as a blown fuse or bad ground to a bad valve body in the transmission. I would suggest a transmission shop to further diagnose since there are pressures that need checked and circuits that will need checked with diagnostic equipment. Here is a description and the testing procedure for DTC P0740. Keep in mind that there is a good chance the trans will need rebuilt.



Possible Causes:

Internal transmission component fault (Input or Reaction shaft) Internal transmission leakage (valve body leaking or seal rings) Converter clutch valve or clutch timing valve is sticking TCC assembly has failed.



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.

My 2002 pt cruiser check engine light came on today i took it to auto zone they hooked up a computer and it came back with 2 codes wrong a p0700 and a p0740 what does this mean and is it expensive to fix


P0700 simply means there is a fault code present in the transmission module (TCM). P0740 Torque converter clutch circuit. This is usually caused by a worn out torque converter clutch which would involve replacing the torque converter and yes it would be expensive to repair if that is the cause. Diagnosis is usually made with a scanner and other equipment.

P0740 code on 2000 Honda Odyssey


Code p0740 is a problem in lock up control solenoid assembly, Check whether scan tool indicates another code. Does the scan tool indicate another code? YES - Perform the Troubleshooting Flowchart for the indicated Code(s). Do not continue with this troubleshooting until the causes of any other DTCs have been corrected. Measure the line pressure. Is the line pressure within the service limit? Repair the hydraulic system as necessary. Replace the Lock-up Control Solenoid Assembly set lock-up control solenoid valve/shift control solenoid valve A assembly and the A/T clutch pressure control solenoid valve A/B assembly. Turn the ignition switch OFF, and reset the PCM memory by removing the BACK UP fuse in the passenger's under-dash fuse/relay box for more than 10 seconds . Using the scan tool, check to be sure that the engine coolant temperature is 176°F (80°C) or above . Drive the vehicle at 55 mph (88 km/h) for more than one minute . Recheck for code P0740. Does the OBD II scan tool indicate code P0740? YES - Remove the torque converter and inspect for a missing torque converter O-ring. If the O-ring is damaged or missing, replace the transmission and torque converter. NO - The system is OK at this time.
