Already had that, thanks to my Dad who used to use it on olde Beetle rear hubs. Was the first time I'd used that, though!
You will need an assortment of internal/external ring pliers and an assortment of pics (think dental instruments). Used some pipe fittings to compress the ~ 16 springs that are part of the front pump. While this was all on a 722.4xx box I don't think the .3xx is much different, other than in how the governor locking mechanism works- a rotating paw in the .3xx, an internal clip on the .4xx There are special tools to establish proper gaps in each of the clutch packs. The new friction discs are a set thickness but you set the exact gap by replacing the steels- these are available in variable thicknesses. On mine the B3 discs (reverse) were the most worn. In that set there was perceptable wear in the steels- of the total increase in gap of the whole set about 15% was due to wear of the steels. But since there was no excessive discoloration of the steel I reused them. My thought was that OK this time the tranny may only go another 200k instead of the 300k it went the first time. And there was a differance- reverse took about a half second to engage instead of being nearly instantaneous. But given that it USED to take 3-5 seconds I was OK with that!
