[Shop-talk] Changing transmission fluid

[David C.]

I believe the thinking is that a flush may push crap back into the 
transmission where it could clog oil passageways and cause more damage 
than it might prevent.

I have a couple of Subaru Forresters.  The older one had about 100K 
miles on it when I had a timing belt/head gasket service done.  When I 
asked my Subaru service guy about a 100K transmission service, he 
suggested that I just do a drain/fill when I did my next two or three 
oil changes.  I did this two or three times and at 125K I am not having 
any problems.

Don't know anything about Accords other than that they are (or at least 
were) pretty good cars.
