for a few months i have been struggling with an overdrive that fails to engage with the solenoid (new one) but will engage if 
i push on the right side setting  lever.  made many different adjustments and none worked.  solenoid will instantly lift the 
left side adjusting arm as long as there is no oil pressure.  it will not lift the adjustment arm more than a few millimeters 
when car is moving.  we had removed the solenoid bracket and replaced a gasket.  not sure what could have happened but 
trans and o/d are now separated on my workbench and i can see nothing wrong anywhere.  checked and reseated ball on 
oil pump and found no grit or dirt.  small accumulator piston moves up and down inside housing assembly.  there were no 
problems with overdrive until gasket change.   any help appreciated.
