Black "grease" on bottom of tranny..

[Shekina]

so i was changing my oil today and noticed the entire bottom half of my tranny was coated in this black grime stuff. its pretty thick and im like 90% sure its not tanny fluid as its not low and teal in color (redline mix). car dont drive wierd or anything, but it looks like it might be maybe a cv boot leaking a flinging grease down there. they looked fine but mybe i should look closer.

what does it feel like when an axle needs replaced?


any suggestions on what it could be?

they go wump wump wump faster with speed not RPM. I doubt it is from that, it is probably motor oil that got heated up on there.

This is for an older legacy (I found it when investigating an oil leak on our outback), but the basics still apply -

hmmm...well thank for the reply. im not TOO worried about it as i think its been like that for a while but i never paid any attention to it. i swear it looks like it coming outta the tanny drain plug, but oh well. ill just take another looksee and try and locate the problem.

posted thinking someone might of had a similar issue.

Maybe it is just some especially nasty road grime. Clean it up real well and see if it comes back?

5 speed or 4eat? I've noticed the same thing you're talking about on the bottom of most 4eats. it's an undercoating of sorts is what i've been told.

its a 5-speed. will prolly just clean it up real nice and call it a day. then ill check and see if it comes back.
