Ford code p0743 and code p0700 what is most likely the best way go about getting to the real problem FIRST... PLEASE HELP.

IT IS INSIDE THE PCM NOW FOR 10YEARS +
P0700 I JUST A PLACE MAKER FOR WEAK SCAN TOOLS. IT MEANS ONLY TRANNY ERROR!
AND MEANS THE SCAN TOOL YOU USES IS TOO OLD
OR CHEAP AND CAN NOT SEE THE REAL KIA TRANSMISSION ERRORS.
FIND REAL SHOP WITH REAL TOOLS TO FIND THE REAL DTC ERRORS.
BEST OF ALL IS A SCAN TOOL MADE AFTER 2008 YEAR
AND IT STATES. CAN_BUS CERTIFIED.

spectra not spectra5

USA
left hand drive LHD, #23is OBD2 scan port #1 is ECM

means using wrong old and lame scan tools
p0700 means transmission error GENERAL( uSA fed code)
means others are there but not using 2008 or newer scan tools
means missing all those better DTC errors
get the car scanned in a real shop using real tools
no kidding.

missing p17xx codes and more.

P0743 Torque Converter Clutch Circuit Electrical
P0760 Shift Solenoid C Malfunction

This indicates a faulty Transmission Torque Converter Clutch (TCC) circuit (0740) or TCC solenoid (0743)

From what I have read about those 2 error codes you are probably best off taking it to a transmission shop.
You'll find information about the P0743 code here http://www.obd-codes.com/p0743 P0743 is a generic error code for all Ford trucks. The P1747 is specifically for the EPC Solenoid Short Circuit
Electronic Pressure Control (EPC) Solenoid, which is inside the transmission. You have to drain the fluid and open the bottom cover pan. Replace the EPC and the filter at minimum; once you have it open you'll be able to find out more.
Good luck with this, it's not going to be a simple fix.

P0700 is a generic ECM/PCM code stating that there is something wrong with the transmission. To get the actual code for the transmission you will need a real scanner to pull the transmission codes. Basic scanners that you can get from parts stores and/or online only read global codes and data, but not vehicle specific codes.

Your best bet is to take it to an actual automotive shop and ask them to pull the transmission codes.

I’m happy to help further over the phone at https://www.6ya.com/expert/jason_00b31cc8f593773a

This code can be caused by low or dirty fluid I would start with a flush and a filter . If not you need a new valve body in the transmission .

P0700 is a request for the check engine light to come on. P0743: Torque converter clutch solenoid circuit problem. Circuit open, circuit shorted to ground, short to another circuit, faulty solenoid, or transmission control computer faulty. Most likely problem is TCC solenoid is faulty. Test solenoid out of vehicle if possible. Replace and retest.

According to the manual

P0700 = EATX Controller DTC Present

Discription= An automatic transmission input DTC has been set in the transmission controller.

.

P1733 no listing in manual

P0743 =Torque Converter Clutch Soleniod/Trans Relay Circuits

Discription= An open or shorted condition detected in the torque converter part throttle unlock solenoid control circuit (3 speed auto RH trans. only).

hope this helps
