Xsara Automatic transmission oil change;

[micha]

Pls help: Should I change oil in my AL4 automatic gear box? The garage
explained to me that according to Citroen's instructions, this box should
stay closed unless something went wrong or the indicator tells us that the
oil is tired… But I think, way waiting for something to go wrong? If oil
change (& filter) can prevent rapid wear – way not do it initiated? The
car has now 57000 km on the clock (about 35500 miles) and gives no problem
with the box. A friend explained to me way not change the oil: "If you
will
change oil & filter now, the box which is used to run with the dirty used
oil will start to give trouble, slip and maybe even burn the inside
entireties because it has build up tolerances and spaces on the pads which
were compensated with the old oil that was thicker then the fresh one,
adsorbed with the wears parts".
So it’s a conflict: Or changing oil now, taking the risk that the box
will go nuts, or change in a few years, and then it will not help either
and the box will need a rebuild.
What should I do? Any reply will be appreciated.
