The valve body does not need to come out. You just drop the pan and remove three screws from the end plate of the K1 accumulator. Pull out the piston with the spring assembly, replace the two springs. Check your seal rings while your in there and put it back in. Put the end plate and the pan back on and the install is finished. I went further and made sure the pressure to the vaccum modulator was what the book called for and had the cable adjusted. At near two hundred thousand miles, this car shifts better than any of my vehicles!
