Do I need a new transmission or can I replace the shift solenoids in question.

Or does it have a transmission module that could be bad? My car is very sluggish taking off, like it is taking off in high gear. I do not hear it or feel it shift, even if I do it manually. And going down the highway @ 60 mph, my tach is showing over 3000 rpm's. Which I know that is high for that speed. My overdrive button does not work at all. I bought a obd2 Diagnostic tool(INNOVA 3100). Which gives me 5 codes. Codes as followed: (P0743) Torque converter clutch solenoid Circuit electrical, (P0750) Shift Solenoid A, (P0755) Shift Solenoid B, (P1744) Torque Converter Clutch Solenoid Circuit Performance, (P0190) Fuel Rail Pressure Sensor. Then on the KOEO test it shows as followed: (P1519) Intake Manifold Runner Control Stuck Closed (Bank 1), (P0713) Transmission Fluid Temperature Sensor A Circuit High Input, (P0743), (P0750), (P0755), again. Then (P1746) Pressure Control Solenoid A&B Open Circuit, and finally(P1000) OBD Systems Readiness Test Not Complete.
