'95 Honda Rafaga (Ascot) ATF change

Hi all.

Own a '95 Honda Rafaga (aka Ascot) 2.0CS, Automatic Transmission, G20A
engine.
Overal distance on the odometer is over 150K km.
The Automatic Transmission Fluid (ATF) has never been changed.

Right now the Transmission is starting to overheat, thus I assume that
it's
about time to change ATF.
I have almost no information about this car in English, as it was made
primarily for domestic market only, neither have car repairers in the
area
(I am from Kyryz Republic, part of former USSR).
Questions:
1. What are the general steps to change ATF in Hondas w\AT overall and
in
Rafaga(Ascot) in particular? Any manuals\FAQ's online?
2. What are possible troubles to face during this procedure?
3. How much of Honda ATF should I buy to completely change the fluid
in
transmission?

Thanks beforehand.
