    Have you tried disconnecting the batteries for 30 min? If no help then the solenoid may be shot. No shifting issues? usually the flashing OD light is an indication of a failing tranny or torque converter.

    The OD light flashing means you've got stored codes. Unfortunately I'm not familiar enough with transmissions to tell you if anything in the trans is messed up but a reputable transmission shop should be able to help you.

    i went down to a shop right when it started to flash 8 months ago they said i need to rebuild the trans it felt fine so i did not have it done and really did not have the money so i ran it plowed every storm and towed 5000 miles since

    Do you run a trans temp gauge? If so does it get hot, say over 180?

    If nothing feels funny shifting-wise I wouldn't do anything so long as it is always the code for the solenoid and the fluid is red and doesn't smell burnt. ATF always smells, but it doesn't always smell burnt.

    the od light is the check engine light for the trany,the ecm knows the trany has a problem i dont know the definition of code 1754 but can look it up later.it could be the lock up solenoid circuit.you would not notice the converter not locking up,usually when the ecm notices a circuit problem or a ratio problem it sets the light,puts the trany into a fail safe mode ;limits lock up,raises line pressure, possible no overdrive depending on what the code is.the only way to diagnose this is to get the diagnostic routine for the code and follow it.you may only need to replace the solenoid pack,or have a poor connection at the case connector.dont guess,use the diag routine for the code.good luck.
