Btw

This is not a ZF transmission, its a mercedes benz transmission and if it tickles your fancy its very close to a GM in design.

That aside, the atsg guide is a good start point, but snap a million pics of parts as you remove them and keep them in order as the arangement of some are unique in every submodel and the only way to get that information is from the factory manuals, none of the automatic transmission chapters were ever translated, there are close to 8 books of it.

Best of luck.
