Re: [AMC-List] BW M12 tran question

["RetroRalph" <retroralph@xxxxxxxxxxx>]

Here is an article on the M-11 and how B&M beefed up this transmission.  I 
don't know how close it is to the M12.  but maybe there is some info there 
for you.

Go to this web page link and look on left sidebar for the newsletter.  It is 
about half way thru the newsletter page...

I heard of local trans shops replacing BW autos with FMC autos.  Don't know 
if was entire Transm or if just the FMC guts in the AMC case.
