I HAVE A 98 AVENGER WITH 71000 MILES 2.5 V-6 AUTO TRANS, THE CHECK ENGINE LIGHT CAME ON, AUTOZONE READ CODES (TRANS FAULT 700) AND (TCC CIRCUIT, I THINK 740, 743, OR 734), BUT I KNOW IT SAID TCC CIRCUIT FAULT. TOOK IT TO THE CHRYSLER GARAGE, THEY CHECKED CODES, COULDN'T FIND ANYTHING WRONG, CLEARED COMPUTER, LIGHT CAME BACK ON TWO DAYS LATER, SAME CODE. DOES ANYONE HAVE A CLUE WHAT COULD BE THE PROBLEM? THE CAR RUNS FINE, NO TRANS PROBLEMSOUT ON THE ROAD. I NEEDS TO BE INSPECTED BY THE END OF AUGUST, IT WON'T PASS WITH THE CHECK ENGINE LIGHT ON. THIS IS A GREAT CAR, PLEASE HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!

 

True Dodge codes are 2 digits 11/71 ... The three digits you give I can not cross to ... From a quick look I see NO TCC codes ... Sure they are not TPS ???

 

THE CODE CAME ACROSS PO700 AND PO734 TCC CIRCUIT, THIS IS ACCORDING TO AUTOZONE AND CHRYSLER/JEEP DEALER. THE SHOP FOREMAN SAID IT COULD BE THE TORQUE SOLENOID PACK OR THE TORQUE CONVERTOR ITSELF. THE CAR DRIVES JUST FINE, ANYBOBY ELSE WITH THIS PROBLEM?? CHECK ENGINE GOES OUT ONCE CLEARED, COMES BACK ON THREE DAYS LATER.

 

P0740 is a torque converter control code and could be an internal problem, and P734 is gear ratio error in 4th gear. If you would like PDF file for your codes, just send a pm.

 

Sorry it took so long to get back to you, on vacation all last week. Dealership said it could be the torque converter going bad, but it doesn't act like it is, it shifts fine. They also said it could be the input and output speed sensors or solenoid pack. I don't want to just chase parts, can you buy the solenoid pack from someone?? Autozone, advanced auto parts?? Etc... I can buy the speed sensors, about $30.00 for the pair. Could it be anything else??? Like i said, it doesn't have any shifting problems, very smooth, no noise!!! Thank you for your help

 

If it's the output speed sensor the speedometer dies ... You never stated that ...
