Why Does ATF Smell So Bad?

[JasonC]

It's the smell of failure. 3 pedals FTW.

That's odd... Seeing there is manual transmissions that do use ATF...

Rear diff fluid is WAY worse than ATF.

Even new diff oil makes me wanna puke. Smells like rotten eggs.

Dead flora and dinosaur diahrrea.
Don't expect that to smell like CK One.

qft...it's even worse when burning it!

I had an 86 Nova with a 1.6 carb'd motor that used to burn oil like CRAZY. Some was leaked but most was burnt

To thicken things up in the crankcase I commonly added gear oil to the engine so as to slow it's oil consumption. Boy did I get a lot of dirty looks in traffic. I pissed off so many drivers with that cars' exhaust. Kinda funny when I think about it tho

Sulfur-based compounds in gear and AT fluids are what give them their characteristic smell.

Here is a direct quote from wiki, "Gear oil is a lubricant made specifically for transmissions, transfer cases, and differentials in automobiles, trucks, and other machinery. It is of a higher viscosity to better protect the gears and usually is associated with a strong sulfur smell."

To a man with a 318is...

It also can be used in a pinch for fox urine to attract slatternly women such as Threehz's mother.

Says man who then talks about the belly buttons of tranny men...

Corrected. I don't have a problem with new stuff. But fuck man, old stuff that's been in use for even a month is the fucking worst.


And I ALWAYS step in the pan, or spill it, or get the used oil on me. It never fails.

Even the new stuff is absolutely fucking terrible.

My old diff tipped in the back of my truck one time and the bed smelled like fish ass for 2-3 months.

Diff fluid is a truly awful smell. Rotten fish seems like a good enough description.

Used Gear oil is the worst smell ever.

yeah don't spill any of that stuff, smell never comes out.

[rasputin]

What do you mean by "bad". I never thought of ATF as smelling bad... Unless it is burned, which it will smell burned. If it does, then you have a problem.

As said above, gear oil just sucks.

same, i can run the machines to flush atf and powersteering no prob, but a new tech doused me in gear oil few months back, he got a black eye and had to clean that shit up.

[Galactodactyl]

Atf is bad, gear oil is worse. I replaced the original gear oil out of a 30 year old shaft drive motorcycle and I had to toss the clothing I was wearing.

The old school Rando 32 hydro fluid is the absolute worst
