Congrats on your successful auto trans overhaul! Sounds like you found the needed info and professional help to ensure the trans worked the first time (nothing like the frustration with a failure and the subsequent R&R to correct the problem).

I found a wealth of info on the M-B auto trans. servicing/testing/internals/overhaul procedures in the Mitchell Automotive Service Manuals. I found the Mitchell manuals at my library for my 1977 W123 and other models, but how far up in model years covered by the Mitchell manuals is unknown to me - I do recall seeing info into the mid 1980's. The trans manual I copied covered the W 4B025, W 3A040, and W 3B050 auto trans. Include are: trouble diagnosis info, road test info including shift points in MPH for various loads, stall speed specs, hydraulic pressure tests, removal and disassembly info with lots of pictures of various sub-components including an exploded view of the valve body assembly/governor assembly/etc., special tools, clearance and band adj. specs., torque specifications, and more.

I do not know if the Mitchell manual is as complete as the info you have, but it is certainly worth a look for those that do not have the info you have and are wanting to see what the overhaul procedure is before deciding to dive into it. Also, I found lots of other great info about maintenance/repairs on other components that I have not found in the official M-B service manuals (print & CD), the Haynes and Chilton manuals. Plus, the info is free from the library (at least our libraries in San Antonio)!

My, very cheap, $0.02 worth!
Tom
