Re: [Amc-list] the strangest things....

[Frank Swygert <farna@xxxxxxx>]

Mark could be on to something there! But as I recall, there was a problem with the rear servo building up and holding pressure in high mileage BW transmissions. The fix was to drill a tiny hole in the servo then put a small cotter pin in the hole, mostly blocking it. That would let pressure bleed down unless the servo was applied directly. So what may have happened is the servo built up pressure, then it went down as the car sat. Could be the fix has been made and the hole was blocked, or the servo seal softened, and the servo "clunked" when the pressure dropped. 

In any case, drive it carefully for a while. I'd definitely consider getting a rebuild kit and going through the trans. It's not a hard to build auto, just one or two tricks to it -- the main one I recall is getting the center sealing rings in place without breaking one. New kits have Teflon rings instead of the original cast iron, so they aren't as hard. I'll see if I can locate that servo fix info. -- exactly what size hole and exact location. Andrew, you wouldn't have that info handy, would you?  

I do know one thing -- don't fix it and the rear band will drag while the car is moving. That will eventually burn up both the band and the drum. The band can be replaced and is easily found, the drum isn't. It's always better to go through something like this BEFORE a major part breaks. Parts are hard to find, and you don't send bits of metal through the entire trans, clogging small passages or tearing something else up.

Perhaps the newer fluid worked into a varnish ring and softened up until the seal released.
I'd be very careful on that first drive.
Get it up to full operating temp. Then drive it gently till I was sure all as well.
A soft parts kit is probably in order. A full rebuild to be safe...
