I'm working on a BW-35 (T35) 3 speed auto trans (flashomatic to be specific) and what it does is to ocassionally 'drop' out of gear - always when cold - does it ONE time and then it's fine for the rest of the time I drive it - until the next time that is - what I am thinking is that it is sucking air - or leaking fluid internally when parked so as to put a air bubble - servo? - anyways there's about 4 EXTERNAL lines to the valve body that seem like a good candidate for this to occur at - they are aluminum - and appear that they have had a nitwit or two fiddle with them already - so I am thinking they no longer fit snugly for a perfect seal - is this reasonable - I am contemplating making a small swedging tool to try and resize the ends - is this a waste of time or worth the effort - what would you "normally" do to fix this???? Thanks
If it was mine Id adapt a modern something to it before it dies altogether and you have to find a $$$$ rebuild kit. Bentdsens and Wilcap would be places to start. Motors Manuals of those years had excellent tranny sections also. Iffn I remember Nash used a GM Hydromatic before the BW; if it has the same pattern as a GM then adapters already exist.
Yes we used to do that all the time in the old days Also check to see if O ring on tube under valve body is intach.It is oil pick up to pump.
Fair enough - I'll rig up something to resize them - I'm thinking making them .001 or .002 too big would be about right - do you recall how much interference you'd shoot for??? As for that O-ring - yes I did look to make sure it was intact and it was, but it was a square cut O-ring and I wondered if the "nitwit factor" struck again - so I was contemplating stuffing a fresh round one in there. Didn't make sense to me that it was square, but then again I have no experience with these so maybe that's right. Thanks for your thoughts.
We used to expand them with a tappered seal pick .Remember o ring being round but have not did one in 15 years.Did lots in the 70s .
