Default Transmission issues

Hey guys I recently changed out my radiator and in the process I didn't screw the transmission line into the radiator all the way and the fluid leaked everywhere on the way to work this morning (Totla bonehead move I know). When I got it home I noticed it wasn't shifting into third gear... I figured it was a fluid issue so i filled her up with tranny fluid. After I filled her up it still wasn't shifting into 3rd. Reverse was fine, 1&2 were good and then it would just rev up and never get to 3rd. I put in my scan tool because the engine light came on

code 0756

any thoughts?? Says shift solenoid B?

Could a dysfunctional shift solanoid be doing this to my car?? Do you think the lack of fluid caused the Solenoid to go bad??

it sounds like a shift solenoid and they are a easy fix just have to pop the pan off and its right there. but i might be wrong running a tranny low is pretty bad for it

The fluid helps cool the solenoids which are continuously engaged (in different combinations of course).
Keep your fingers crossed.

I just replaced both solenoids (1-2.2-3) took her for a test drive and I still have the same problem. The car shifts fine from 1st to 2nd, but wont shift from 2nd to 3rd. Any suggestions?? I am afraid im screwed and may need to rebuild the tranny.. sighh

Toasted 3-4 clutch pack. Lack of fluid will likely fry clutches before burning out solenoids.
