2015 JK in limp mode. Code was P0743. One transmission place said it was an electrical problem and would not give me a price to go through the whole electrical system. Took it to another transmission place and had transmission fluid and filter changed and torque converter clutch solenoid circuit replaced but that did not fix problem. Told me I needed a rebuilt transmission. Told me parts were on back order and they are not nice at all when I call and ask about the Jeep. Help! I am worried that a rebuilt transmission won't fix the problem either-is it electrical or is it the transmission?
