OHHH...that is a sketchy question. I'd do a whole bunch of research and decide for yourself. Many legit transmission people will say that swapping everything over 100k miles is dangerous because the clutch particles will be removed and reduce the friction on the plates and cause slipping of the transmission..."if it ain't broke don't fix it." Others say it's okay to just swap the fluid or swap fluid and filter...definitely don't do a flush. The question is likely to start many arguments. I'm surprised no one has chimed in yet.
