PO715(Input turbine speed sensor malfunction, circuit A)
PO743(Torque Converter circuit electrical)
PO750(Shift Selonoid A Malfunction)
PO755(Shift Selonoid B Malfunction)
PO760(Shift Selonoid C Malfunction)
Vehicle drives, yet while in drive, takes off sluggish and will not go into overdrive.
After clearing codes, check engine light and OD light are on, with the OD flashing. Have mechanical knowledge and experience, but this has stumped me, not sure how to proceed. Any help would be greatly appreciated.

Vehicle drives, yet while in drive, takes off sluggish...meaning exactly what? Like it is starting in a higher gear than 1st? Or does the eng. rev. higher than seems normal? and will not go into overdrive.Is this the main concern with malfunctioning?
After clearing codes, check engine light and OD light are on, with the OD flashing. Have mechanical knowledge and experience, but this has stumped me, not sure how to proceed. Any help would be greatly appreciated.My guess is, that the computer is confused by issues creating improper internal shaft speeds comparison, possibly due to 2 concurrent mechanical failures. The OD light flashing indicates shaft speeds are not as they should be for the given operating conditions. For example, if the Torque Converter Clutch fails to engage, the engine speed (which PCM knows at all times) is different from the trans. input shaft speed: those speeds should be identical, when the clutch is ENGAGED. This condition of shaft speed inequality is revealed by the PCM causing the OD light to flash; a trouble code may be read using the appropriate code-reader. Most after-market check engine code readers will not respond to the OD flash codes.
