700 tells you that there has been a "transmission control circuit malfunction", and 740 basically pinpoints the possible culprit, which is "Torque converter clutch control circuit malfunction". If you don't notice any difference in the way the transmission is shifting, especially when you are at cruising speed on highway, or you've basically reached the speed your going to travel at, and are no longer accelerating, your converter normally goes into "lock-up" and your engine RPM's will drop by approx, 200-300 RPM's. When your driving it basically feels like transmission shifted again, slightly. If all feels well, it may just be a one time thing, but being how transmissions are somewhat temperamental, as well as expensive to repair when big problems occur, I would certainly consider getting it in to a dealer for diagnosis at least, and see what they come up with, as it may only be a bad switch, or bad, corroded connection causing the codes. Remember, if it sounds like an expensive,extensive repair, then simply get all the info, and either stop elsewhere for diagnosis of same problem, (without telling them it's already been diagnosed) and see what second opinion has to say. If in doubt after that, get back to us, with diagnosis results, and we'll be glad to help you decide from there. One thing you may want to consider though, is a transmission service, (oil and filter change) if it hasn't been done in a while, just as a preventative maintenance thing. Changing of oil and filter in those transmissions at regular intervals, is a good way of extending the life of them. I recommend the new ,Autopar ATF4 transmission oil, which is more expensive, but guaranteed to last for lifetime under normal driving conditions. Chrysler/Autopar products tend to work better with it, and new filter, although there are many mechanics that will argue that fact, there are just as many mechanics and owners who have seen other oils cause problems, and when they switch to Autopar, those problems disappeared.

It means the body computer has found a problem in the transmission or the module that controls the transmission.

Both codes are for transaxle problems.
Code 740 is the torque converter and code 700 is a general fault with the controller.
You'll need to take it to a shop that works on transmissions.

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.

Check engine light is on 3 codes p0740,p0601,& p0700 what do they mean


P0700 - Transaxle Control System Fault Conditions
The P0700 code is for information only and the next step is to check for transaxle codes in the Transaxle Control Module (TCM). So you'll have to have the dealer or another qualified shop/technician pull the transaxle codes from the TCM and go from there.

P0740 - Torque Converter Clutch Circuit Malfunction

P0601 - Internal Control Module Memory Check Sum Error
What does that mean?
Basically that means that there is an interal fault in the Powertrain Control Module (PCM). There have been many reported PCM failures on Chrysler/Dodge products although it is possible for this to happen on any vehicle. In Dodge/Chrysler products, a P0601 trouble code means that a serial communication failed inside the computer at least 6 times.

Symptoms
Likely, no symptoms will be discernible to the driver, other than the illuminated Check Engine Light. Typically the engine runs fine, gauges work, etc.

Causes
A code P0601 in most cases means the PCM has gone bad. This is possibly due to a short-circuit inside the PCM. Or, if you disconnect the wires/connector from the PCM while the battery is still connected, that may also cause this code.

Possible Solutions
With a P0601 OBD-II trouble code, the most common fix is to replace and reprogram the PCM. In a few cases the dealer may be able to reflash the PCM and get it working. But more than likely the PCM will need to be replaced and reprogrammed (we recommend you take it to a dealership for this). The good news is it *may* be covered under your emmissions warranty. So even if you're out of bumper-to-bumper warranty or powertrain warranty, check your warranty guide or dealer to see if this is covered.

Other people have reported that they cleared the code only for it to return again and again. Keep in mind that most shops can replace the PCM but not all can program it.


Good luck!

MY 2004 CHRYSLER 300M CHECK ENGINE LIGHT CAME ON AND A P1776 AND P0700 CODES CAME UP, WHAT DO I NEED TO DO??? DEBBIE


p0700 indicates you have trans fault present..p1776 is a trans fault which means solenoid switch valve is latched in low/reverse position..solenoid switch valve is located in valve body of transmission,but for 2001-2004 LH vehicles you need transmission event data read to find out what TRS position the fault set..recommend chrysler dealer for this fault..also build code on solenoid pack in trans must be checked..if in a certain build code range,you replace solenoid pack..not the valve body..valve body must be removed to check build code on solenoid pack..i have seen this problem before..i am a dealer technician, and had one of these fault codes last week and solenoid pack was the problem..solenoid pack is about 375 dollars..total time with diagnostics was about 3 hours..

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.
