GEN 2 Transfer Case Transmission Diffs Oil Changes. When?

[thatJeepguy]

Prolly got the trans flushed and not changed the filter.

FordTechMakuloco says rear diff 30k - 60k depends on towing/hauling etc.

Front diff every 60k depends on how much 4X4

Tcase every 30k

I adjust depending on my own use and conditions

Looking at about $120 in fluids so not too bad.

yeah i figured id do tcase every 25k-30k with the trans, but changed it @ 15k after some offroading the oil was black so doin mine every 10k.
Interesting on the rear diff, i change mine every 50k, but fluid still looks good. Im all for maxin out the lifespan of my stuff so interested on your take on 30k intervals, may start doin that too. Also, whats your take on friction modifier? Its not needed per say but read/heard its not bad to add.

Friction modifier is for clutch type limited slip differentials.

Gen 2 has electronic locking, Friction modifier is a waste of time and money. Although some gear lube comes with it added already.

Yeah only asked cause the amsoil version comes with it. Usually stick to the mercons for everything past the motor. Thanks
