I have been looking around for Type A and I guess it is no
longer made.  I called a major tranny shop and they do not go back that far and
NAPA has only
the current stuff.
 
What is an acceptable solution?  I have no idea what is in
the tranny now.   It shifts just fine but does have a little leak in the front
seal.  If the answer is Dextron, do I have to do a total purge because of any incompatibilities? 
Thanks.
