Hi everyone;
Is it necesary to change the manual transmission fluid, or just refill
when low?
If necessary, after how many Km (or miles)?
Thanks in advance for all your answers.

The early years of the S series mfgr manual called for an early change at
approx 10,000 km and further changes at ???100,000 km???? intervals. The
later years (with the same manual trans) did not call for these changes. I
can only speculate as to why the reduction in oil change recommendations.
I found that with both of my cars that the oil from the first change had a
very silver metallic sheen and appeared to contain a large amount of very
fine metallic material which I concluded came from the break-in wear. This
caused me to shorten the second change interval and to continue to change
the fluid regularly afterward. The trans only takes about <3 liters of
fluid and the drain plug is in an easy location (much better than the engine
oil filter) and the drain part is easy. Use sealer on the plug and DO NOT
over-tighten. Refilling is also easy if you have a funnel with a long hose
that will fit inside the dipstick hole.
IMHO transmissions are expensive to repair and clean oil, and gentle
shifting at reasonable engine speeds, are the cheapest way to extend their
service life. The cost of clean trans fluid is so low that in the big
picture it is almost zip. If you are a handy guy you will probably have
many uses for the almost clean oil that you drain.
