Re: 71 BW Auto Tranmissions

[farna@xxxxxxx]

The old Ford Cruise-O-Matic (and Merc-O-Matic) and the FMX are all versions of the BW trans. Originally BW and Studebaker pooled resources to develop an auto trans, then were joined by Ford. Ford manufacturerd theirs rather than buying complete units from BW -- there may be actual BW parts in the Ford units though, not sure. I do know that they are pretty much the same EXCEPT for the valve body, and maybe some of the passages in the trans case. Ford uses their own design valve body, so shift kits won't work. The clutches and bands will interchange though. 

Volvo used a BW 55 and 65 through the late 70s. If you need a BW trans built check for shops familiar with older Volvos. US Post Office Jeeps used the BW 35 through the mid 70s, so shops that worked on them a lot will have some BW knowledge as well.
