Yep, but it's also interesting that even when removed on my '87, the tranny still shifts fine either on boost or off. I think it was an over-complicated solution to a problem that existed in the early/mid 80's where they had the tranny valve body programmed to shift excessively firm, and the BFS was an attempt to soften it. Maybe it worked better with new transmissions, but with our old/used ones, the BFS appears to be unnecessary. Further proof is that the transmission, and valve body, is the same for 90-93. That seems to indicate that MB finally decided the BFS simply wasn't needed anymore, without any change to the trans.

It is tight in the tunnel, but until I know what I need to get it out I'm not sure how nasty it will be.

The modulator replacement is not in the FSM, at least not in the CD-ROM version. It's in the WIS, but the procedure is painfully simple (see attached).

Nope, the pan can stay attached. I vaguely recall that some fluid would dribble out so have some rags or paper towels handy. It's not necessary to drain the pan.

Probably a good idea, but since it's so simple to just swap some tubes, you could test both before & after if you want...
