Auto transmission flush

[t5_jim]

ok last job on the agenda for my 850 t5 auto is going to be the transmission flush. Reason being is that there are no records of it in the service history, the car is now 19 years old and its the only fluid in the car I have not yet changed.
Should I go for dextron 2 or 3? Im thinking dextron 3 as it superseded dextron 2.
will probably flush it 3 times.

Thoughts?
Thanks peeps

I would put either in mine it won't hurt it - I used that Carlube ATF-U

For flushing I did a change and am running it a bit, i.e. using the car on the road in all gears, then changing again
