Po740 is possible bad torque converter or sometimes the o-ring around the torque convertor is not sealing around the torque this is what honda says about the code

It means you have an internal transmission problem. Your vehicle may fall under an extended warranty from Honda. Honda extended the warranty to 100,000 miles because they have alot of trans failures.

Code p-0700 / p-0740 how to clear code

To clear the codes is the easy part, you can use a scan tool or remove the battery neg terminal for 5 mins but the codes will come back.

the PO700 is a code that tells you there is a ****** code which is the PO740 code. the PO740 code means the TCC circuit has a problem. this could mean there is a bad tcc solenoid or wire to tcc.

I would have this problem checked out asap. these vans have a lot of problems with the transmissions . your problem may be as simple as a solenoid pack problem. these vans with transmission problems can get costly, having it checked now would be wise. if you had a scan tool to get all ****** switches and solenoid value readings i would be able to help you check it but a ****** shop can check it with in an hour. good day.

PO700 PO740, check engine light on. Run a test on

PO700 is a code telling you there are codes in the TCM of some late model cars where the Transmission control module has lost connection to the PCM the vehicals main computer , And basically it happens when the TCM has a issue within itself or the transmission that sets a code and it sends a request for the PCM to illuminate the SES or CHECK engine light.
PO740 is a chrystler specific code that involves your Tourqe Converter Clutch Circuit (specifically The TCC solenoid) this code if not repaired quickly could cause major transmission problems....slipping out of gear....not shifting from first to second properly and just all around trans problems...eventually leading to no shifting at all...I highly recommend fixing it soon.

Code PO740 and PO700 show on scanner for 2002 Chrysler Sebring LX. What's going on?

Best to have a transmission place work on this.
Here are the meaning of the codes:
P0700 Transmission Control System Malfunction
P0740 Torque Converter Clutch Circuit Malfunction

It maybe cheap to fix like a bad sensor. Or it maybe something serious going on. Best to have a transmission shop check it out.
Good luck.
