Got this covered with a recap of my install:
Step 1: remove vb
Step 2: place vb on bench
Step 3: seperate vb and leave screws and all in top half
Step 4: with VB apart, foolishly lean the top half against crap on your work bench.
Step 5: allow above scenario to lead to everything falling all over the place
Step 6: reassemble
Step 7: notice accumulator spring across the bench after reassembly
Step 8: disassemble hold down and see both acc springs missing
Step 9-12 involve language not suitable for the general audience
Step 13: enjoy better shifting and holding
