Bakit pag manual trans simula nung 80s 90s ilan klase kotse na dumaan eh hindi pinapalitan gear oil.... No problem....

Meron time pala na nagpalit nung nagkaleak lang. Bumili lang ako gasket/oring eh ayos na ulit..

Pero ngayon mga current user manual iniidicate na palitan mt fluid?????? May pinagbago ba components mt or kailangan lang quomota ang casa?

Kaya natutuwa ako sa mt eh good for the environment..... You dont throw oil.....pang lifetime na gamit..
MTs are built to larger tolerances, compared to ATs. someone once said, "ATs are built to swiss-watch-like tolerances". overkill description, maybe, but google some pictures, po, and you will get the general idea.
as such, ATs are more sensitive to lubrication issues.

some of today's casas do have this reminder to "change this... change that..." as part of their customer service. they even call or text me, as reminder! it's easier now for them to keep track, because of computers. there are many car owners, kasi, whose idea of car maintenance, is to replace the pine-tree car freshener hanging under the rear view mirror. heh heh.

yung ibang kotse naman, ay naka-program na sa car's computer, to remind owners that it is time to change this or change that. hindi ito casa-level decision. manufacturer's decision level ito. casas are simply "benefiting from the situation", if one would like to put it that way.

the only time i replaced my MT's gear oil, was after ondoy. i had it checked, and it looked like coffee latte. definitely water-contaminated!

and yes, oil does not die. but it does get contaminated. and its additives that make it a better oil, do deteriorate.
