Here are the instructions for a little bit more of a visual.
Here is where you can see that I use the spacers as directed but use Plain, White, Red for both accumulators. This helps firm up the 1-2 shift just a little. You can also order the 2-3 spring that goes above the piston and use that for the 1-2. GM part number 24203977 is for the spring and will also help firm up the 1-2 shift.
Since I used the Red spring in the 1-2 accumulator what I do is leave the 2 yellow springs that come stock in the 4th accumulator and then add the last remaining yellow springs that comes with the kit. There will end up being 3 yellow springs all said and done.
Here is another good resource if you wanted to go the DIY way.
