Contour Enthusiasts Group Archives Forums Modifications Transaxle Watch out

THat may explain it, someone adding more modifiers to the mtl to the fluid in the trans in question I mean.
From the smell that Terry described it sounded like standard gear oil. MTL doesn't smell like that, mostly GL-5 oils seem to smell like that!

The MTL fresh from the bottle that I remember was very mild in smell. Do you recall what yours smelled like?
Does anyone with a fresh bottle who also knows what a hypoid gear oil smells like, think it smells like that?

When I used ATF + friction modifier I had the most intensive wear in my transmission! It was for about 3 weeks to a month and of course the Torsen was breaking in, but it was significant in the metal particles. When I dumped the fluid it totally REEKED of the type of smell that Terry described! I changed it out because of poor performance and switched to MTL. My transmission never worked better than when I had MTL in it. I ran it for over a year and then switched to Royal Purple. Not satisfied with that I'm now turning to MT90 and I found that even MT90 doesn't stink like what is described!

I also ran Torco synthetic a long time back and that may be what protected my stock diff from blowing up as that is the last fluid I ran before putting in the LSD. I ran that for about 1.5 years. No wear from it either. Of course the shift forks were binding like hell from the previous factory lube but I got all that fixed up and its been shifting smooth as silk for over two years.
