Heavy for max durability

 

Mine just recently stopped making this smell.
I wonder if I should be worried?

 

Mine didn't stop but rather faded away. Its not that bad any more almost unoticable, it just comes up every now and then when im making hard turns.

But then again we might be getting used to the smell...

Interesting find on Redline Australia's site:

I've had this problem since last June. I've never removed my console or shifter. The mechanic at the dealership can smell the gear oil, but finds no leaks and has no answer to fix it. The smell virtually went away during the colder parts of winter, but as soon as it got warmer it came back.

I'm planning on changing my gear oil in a month or two. Mabe I'll try the stuff that Team was talking about.

 

^^ What does that have to do with gear oil smell?

 

Two questions:

Can I use this in my 8 if it's my daily driver? What do you mean despite adding the AFSTS?

 

Who, me?

 

I think he was referring to my post. If you click the link it recommends the Shockproof lightweight for our tranny if you race. This is the product Team is using except that he is using the heavy version. I'll tie it all together here: The Shockproof is said not to smell.

 

I got it.
The shockproof smells the same to me (in the bottle).
I've had more recommendations against the stuff over the years than for it. No science to back that up, though.

 

With the distinction between cold and warm weather driving and the odor's occurence, I am still tending to think that my theory about flow channels and the technology of clinging fluids are somehow the cause(?).

 

I changed my tranny fluid out about a month and a half ago with RP75W90 and I know I spilled some so I thought that is why I am still smelling the gear oil. After reading this thread I wonder if I have the same situation. I'll crawl under there and look this weekend. Put mine in the fill hole till it started to come out. I smell it when I get into the car in the garage. Don't notice it while driving.

 

I have a slight smell in mine for the same reason, but it was much stronger than that after warming up with the old sulphur based oil. That's gone now with the Shockproof oil change.

I'll check again, but at the time I installed it the Shockproof smell was significantly less than the other gear oils I've used in the past

 

Response from an email sent to Redline:
I just compared the smell of the
MT-90, the ShockProof , motor oil and 75W90. If owners are
experiencing gear oil smell in the interior it may be coming from the
differential rather than the transmission. The MT-90 smells similar
though not quite as strong as the motor oil, the ShockProof is a
little stronger, the gear oil has a very strong sulphur smell. I
would be surprised if you could smell the MT-90 in the car,
differentiate it from general smells.

Well, I changed my own gear and diff oil to Royal Purple last week and I don't have a single smell of it anywhere.

 

Bump
Took the 8 in for an oil change, new headlights (film issue), and the gear oil smell.
My dealer couldn't find the source of the odor. They've fixed everything else to date. Anyone else found the source yet?

 

I replaced mine a week ago. I measured out the 1.8qt and poured exactly that in - new drain and fill gaskets. No smell but much smoother shifting <crosses fingers>. Did not alleviate my high RPM 1-2 shift though. Grrrr.

Doing the diff tonight. I wanted to do them separately to see if maybe it was one not the other - or hopefully none.

 

I wonder if Royal Purple is just smelly. The dealership changed my shifter, and my leather shift boot, but not the rubber shift boot. My instinct tells me it'll return even though I tried to clean the rubber shift boot as well as I can do it. I lost one of the nuts into the area underneath handbrake assembly in the process too. DOH!

 

That nut can be fished out. Try a chopstick (or something similar) and duct tape on the end of the stick. I had to do this for that stupid "fragile clip."

 

It's really really in there. I'm going to pick up a magnet on a wand from Sears after work today.

 

Currently putting in the Redline diff fluid - man is that stuff stinky and SLOOOOOOW. Much smellier than the trans fluid.

 

fwiw, it's not how it smells at room temperature, It's how it smellls once it's up to operating temperature. That's when the the real sulphur smells get released

 

Kinda like your underwear.

Sorry...

 

Yup. When the car is cold there really isn't any smell. After a 30 minute drive though, it can get much worse.

 

what exact brand does mazda use stock??

(oh and add me to the list, RP stink.)

I may try shockproof shortly before the real summer heat kicks in here the the northeast.
