I did not use the override switch as the coach was new to us and was not aware of it existence.  Lets compare your situation with our experience.  Your slide is retracted at the top and the locks are extended thinking its stowed. The bottom has not completed its retraction sequence. i.e. retraction switch not pressed.  That switch is in the lower basement overhead about the center of the slide I am thinking if you wedge a shim into the gap engaging the stowed switch the HWH logic board will now think all is retracted.  May not solve you transmission problem but you will know its not the slide.  Feel free to call me at 352-245-1808.
