Tranny fluid smells terrible

LOL...yeah, friction modifier smells like a mix between body odor, antifreeze, and fried onions. It is literally nauseating.

95gts- consider this before you add it:

Friction modifier is what allows the clutches in your differential to slip when turning, allow different wheel speeds. It is not conducive to locking up your differential, it is conducive to allowing it to slip.

What kind of fluid are you putting in? Most modern differential fluid you buy already has some fricition modifier added into it, enough to allow your clutches to slip while turning.

Adding extra friction modifier can contribute to your clutches slipping when you don't want them to, ie off the line at the drag strip.

I thought I needed to rebuild my traction-lok a few months ago because it was slipping. I changed the fluid, adding friction modifier, and it began working again, only to start failing a few weeks later. I changed the fluid again and did not add friction modifier, and it locks up beautifully now.
