Check engine light is on and code scanner shows codes P0743,P0750, p0755, p0760, on 2000 Ford Taurus

respectively torque converter clutch solenoid circuit electrical,and shift solenoids A, B. and C malfunction. I hope there is a relatively inexpensive fix that will turn off the check engine light and eliminate the codes. The transmission shifts ok and I get 28 to 30 mpg on the highway. It will not presently pass an emissions test with the check engine light on.

You will need to rectify the problems with these shift solenoid circuits and the TCC circuit as well. You may even need to replace some of these solenoids. This should not be too expensive, as long as you know how to remove the transmission pan and access the valve body.
