Automatic transmission service confusion

I want to check and service the automatic transmission in a 1994 525it. According to Bentley it is A4S 310R. Bentley suggests that an authorized BMW dealer with the appropriate temperature measuring equipment is the only one capable of checking the ATF level.
I have to assume that one of you know a way around that requirement.
Is the ATF fluid strainer the "filter"? Do you simply clean it and replace it?
I have read some interesting DIY transmission fluid changes for the e34 but they are vague in some change the filter. Bentley does not mention a filter that I can find.
RealOEM. does not show a filter.
The transmission is fine but I want to do some preventative maintenance.
Does anyone have a procedure?
Some sites suggest that one should just change the ATF if there is any doubt about service history.
