same as muffler bearings... why not find where it leaks first. i guess its and automatic, transmission?and has 4wd and with a transfer case (it too can leak)imagine its box. a box has 6 sides.one cleans it and then drives, and find which side leaks.only evidence works here, clean, drive , find. location.the other way, is to use the dye, kit and light.add dye to oil/lube, then drive, then come homeand use the light (comes with the kit) and find it.or get the car fixed, this is what they will do..... pay them.leaks have many causes.1: bad gaskets. or vents blocked,2: loose parts.3: bad o-rings, seals.4: bad castings, called porosity failures.
https://en.wikipedia.org/wiki/Casting_defect5: and more, cracks.? warpage,,,, ext, dampageeven road collision damage . or things you hit in the road.we can't just guess , any of this, only tell you , the car needs service. and why ask the blind? I find all my leaks, by , clean,drive ,look repeat.works every time, but takes hard work.SELCO. my wild guess, that is someone told youin a wild and useless guess, not inspected.the shift selection shaft seals leaks. good luck and remember you never told us what drive line is in your car. not one word, all we know is the body shell name. (mostly useless)nor if in usa, they have rodeo's in Australia too.some there chock full of HOLDEN parts.ALL car work, diagnosis , is a hand on deal.using real mechanics and all that.Many cars leak oil, and is ignored.Some are very hard to find,.may are cause by lack of service. when you service a car the mechanic's looks overthe whole car (you didn't) and he sees,omg, the trans tail shaft leaks oil. (only it is wet) so tells you, that it leaks, ATF fluid. (pink ,/red)and needs a new seal, see? then you ask how much is that?,then he or she says.if just seal, it's $15+ 1hr laborif the yoke is damaged, and 1hr, and $100if the last joker damaged the tail other housing at the seal, the cost is a new housing.that joker never heard of proper seal puller.not any of which can be guessed at. ever.one must take it apart and see what is up.that is what the mechanical world is like.unless a new $3000 tranny is in the cards, just for one leak.the common leaks (means nothing really)are:tail shaft seal.front seal.pan gasket leaks due to last service, done wrong.pan drain, if it has one, the seal ring bad. o(front ,rear, bottom are the common sides.)and the shift manual selector shaft seal bad.
