Re: Rattle in automatic transmission

["jtrealty@xxxx " <jtrealty@xxxx>]

There is no "O" ring or other seal for the trans dipstick at the top 
of the tube. There should be no clacking noises comming from the
front 
of the trans. At the extreme front of the trans is the fluid pump 
which is turning all the time, It is driven by a shaft from the
engine 
and always turns at engine speed. It would either always make noise
or 
not.This is a good time to take the car to someone who is familiar 
with the trans in the car to look at and can better tell what the 
noise is before ripping into the transmission. I think there is a
shop 
in florida that has worked on "D"s.Taking the pan off is a good idea 
but you may have trouble getting a filter.Chances are if there is a 
problem inside then the damage is done just don't wipe out the case.
