Fluid ok, PNP seems ok but about once a day while driving at different speeds the arrow will come on (limp mode) and I pull over and turn the ignition key on and off 5 times and the arrow resets and arrow doesn't come back on the rest of the day. Auto Zone pulls code P0750 solenoid 1 or A. First of all, I,m having a hard time locating this part and was really hoping that someone would have replacement instructions for this part.

Note: Sometimes the arrow comes on while slowing down to a stop light and sometimes while crusing at 70 on the interstate. Could it be the kickdown switch? It's hard to check because it's on the firewall and not sure how to do. There's some info on replacing the solenoid on some Volvos but not the S90.

Any help would be great, Scott.............................
