Hello, So I have a 2007 Kia Spectra with 145,500 miles on it and my check engine light will go on and then off a few times a month. I went to several places and did a test for the check engine light and it came up with 6 codes. P0700 = Transmission Control System Malfunction. P0743 = Torque converter clutch circuit electrical. P0750 = Shift Solenoid A P0755 = Shift Solenoid B P0760 = Shift Solenoid C P0765 = Shift Solenoid D The check engine light off again, but the codes above are the only codes that will come up. Kia said I need a new tranny, but when I took it to a tranny shop they said its electoral. The tranny will downshift once or twice a week. When this happen the engine light will come on. The car will accelerate slowly and would not shift. I will turn the car off and 2 mins later I will turn it on and it will drive normal
RepairPal Certified shops can diagnose and repair your 2007 Kia Spectra. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
It's going to be hard to diagnose without a hands on inspection. But I agree that it sounds electrical. If you can restart the car and it works ok for a while that doesn't sound like a hard mechanical fault.
At this point I recommend a second opinion. Here is a link you can use to find another shop near you.

Hey Alex, yeah once in a while when I'm driving it will downshift , start to accelerate slow and the check engine light will come on. I would then pull to the side of the road, turn off the car and then the car will start and drive fine. Most of the time, I will turn the car of put the car in the lowest gear move it up to park and then start the car and its fine.
