What is it that you need to know?
Its basically the same as some middle 80's MB sedan tranny. |

Your early 3 speed would be a Porsche A22, with internals of a MB 722.2 transmission. If you search online you can find mercedes manuals and transtar has parts. Even better, buy the CD's with WSM + separate manuals on the A22 and later A28 transmissions.
A28 is same as 722.3 Mercedes internals, specifically a subversion W4A040, where the 40 designates the higher-torque capacity of the transmission, usually for V8 Mercedes sedans it appears. (This is what I've found in researching it, trying to fix 722.3 4 spd transmissions).
