No warning needed? On this thread alone there are two people who did it; and for some reason you yourself thought to warn another poster on this site in another thread about doing it.
"The B2 and B3 servo springs push against the interlock cover so before unbolting the interlock, the B2 and B3 adjusting screws have to be backed out to relieve some of the spring pressure. The risk there is that the band actuating struts will fall out of place if the adjusting screws are backed out too far. Each strut is a small, approximately square part that's the final bit of linkage between servo and brake band. The struts aren't pinned or held in any way - they're loose. Servo spring pressure keeps them in place. There's no access to replace a strut without taking the trans apart."
