Chevy 341 transmission (muncie 3 speed)

Good morning to all. Could someone please direct me to a webpage were I can figure out all of the ins and outs of the 341 tranny behind my 56 235? I'm needing to find a manual online or where I can buy one. I would really appreciate it. All I'm finding online is pictures of a bare 3 speed and the swap information. Thanks andGod bless

 

Go to Ebay etc and get you a 55-60 copy of a "Motor's Manual" . Will answer many ??? now and later.
