92 300E transmission service question.

[Bob G]

My 1992 300-E has 37,000 miles on it and is due for its first transmission filter and fluid replacment. What specific tools will I need Torx or metric sockets? I cannot fine any good information even in the Haynes manual this subject is breifly shaded over but not discussed.
I wish to do this service right and would like to know as much as possible . The engine is a M103-983 single cam 6 cylinder with an automatic transmission. I have the sport line models and am not sure that that changes any of the service requirements any but I thought it should be mentioned .what are the tork valves for the drain plugs and tighting of the pan bolts with a new gasket?
Is there a manual I can buy that covers the transmission serving and repair.

Thank you
