I took my car to a transmission repair guy and he noticed that I had my muffler welded close to to trannie because of a leak. He said that they probably didnt dis connect the positive terminal on my battery before welding and cause my (TCM) trans control moduel to fry causing the false codes. He also tryed different silonoid packs and notice that the computer read out was picking up that there was closed circut in drive. Then He told me to go to ford and have them flash the (TCM) or PCM and see if a boot would fix it. Ford told me there is no TCM on my car only a PCM and charge me $95 to flash and still the problem occurs. I for got to mention that the car is in limp mode but just now started to be a consistent thing daily. Before it would happen weekly. Any info would be great. Thank you so much

P0743
TCC solenoid control circuit is open
TCC solenoid control circuit is shorted to ground
TCC solenoid wiring harness connector is damaged
TCC solenoid is damaged or it has failed
PCM has failed
The Torque Converter Clutch (TCC) Solenoid controls the lockup and release of the torque converter clutch. Problems here can make the transmission feel jerky at low speed if the torque converter locks up too soon or fails to release soon enough, or cause a drop in fuel economy if the converter never locks up. Causes here include a faulty lockup solenoid, a sticking lockup valve, grounded lockup solenoid wiring or a missing lockup solenoid spacer plate screen.
Solving this problem may solve the transmission issue.
Yes Ford is right there is no tcm, only the pcm controls the transmission (4R70W transmission)
Don't worry about the other codes, just focus on fixing this one.
Here are the transmission controllers
