The 4HP22 was used until replaced by what I believe is called the 4HP22E, which is the electronic version of the same box, and is externally pretty well identical. They both fit in a RRC, but I guess you need to be an electronics engineer with DIY tendencies to use the 22E. (Ask me how I know all this!) ;>)
I'm fairly sure the change to electronic came with the Disco II. You can distinguish the two by the fact that the electronic has no kickdown cable, and a multiway electrical connector in the casing near the selector shaft. Hope that helps!

There are some great articles on the magazine section, especially servicing the ZF 4 speed slush box.
