This is a factory, stock EPC solenoid, from what i gathered it is the solenoid that provides fluid to all the other solenoids, hence the additional pressure and volume. From what others have said, it provides a hard 3-5 shift that some do not like. I have not noticed any additional benefits, leading me to beleive that maybe my EPC solenoid (the one in the stock location above the valve body is worn. I may by another EPC and remove the valve body and install it to see if that helps crispen up my shifts.
Sinner, thanks for the input, I'll change the external filter this week. Does that have anything to do with line pressure? I would think so since the oil cool is not high pressure.
Check out "shift Flare 3-5" thread in general forum for additonal input on this.
