Tranny smell...
 

This could be a stupid question, but I wanted some other ppl's opinions.

Vehicle: 2000 SiR coupe.

Every now and then (maybe once a month or less I'll notice this), under normal driving conditions, I can smell a gear-oil smell (manual tranny fluid). It's not strong, kinda faint, but I can smell it. I've looked for leaks numerous times only to find the bottom of my car bone dry. Tranny fliud is full, topped it up a short while ago. No leaks from the axle seals either. The tranny shifts fine. Sometimes crunches into 5th (I hear thats normal for an SiR 5 speed tranny). Original clutch (starting to slip under hard shifting).



Just curious why I would smell it time to time....I can't figure it out.

Any thoughts?:shrugs:


Thanks.:)

maybe its not MTF....could be power steering fluid, i don't have the greatest sense of smell, but they sort of smell the same to me....check out the pump, resivoir, lines and rack.

I smell that at various times on highways or in the city around trucks...gear oil stinks...mtf doesnt have a smell really cuz motor oil I dont generally smell unless its burning...but gear oil f'in stinks

MTF definately has a smell, and i've got a crappy sense of smell, so does oil though.
But i'd agree some 75W80 (or similar) definately has a very pundgent smell.

gear oil does NOT smell like MTF.

I'd say old cv grease smells more like it. Give your boots a good luck over, just run your fingers against all the creases along the boot see if you can pick up any grease. If not.. the drain plug uses a crush washer that could cause a tiny leak, but not one strong enough for you to smell, but doesnt hurt to look.

If that both checks out.. do what zeeman suggested about the p/s system

Everything looks good....I think it may just be because I commute where there are alot of big trucks and I never thought it could be coming from one of them, I think that is the case.

Thanks for all the help non the less!:thumbup:
