Brian,
Here's a list of the 930 transmission tools off the top of my head.
synchro hub removal tools
These are thes only "special" tools. Pelican sells them.
1st gear tool PEL-TOL-P224
3rd/4th gear tool PEL-TOL-P223
You can get by without these rather expensive tools, they just make things much easier/quicker.
Note: These tools are weaker than there 915 equivalent. I found it necessary to heat the dog teeth in order to pull them off without damaging the tool.
gear puller You will need a puller with long arms. The one I use is made by Kukko, I have a 2nd set of longer arms (not pictured) that I use.
hydraulic press to R&R the synchro hubs (aka dog teeth)
hope that helps
-Chris
