I've got a haines built tranny with Quaife. Ran MTL since installing it about 2 years ago. Drained and filled with MTL during the engine swap in the spring of '04, didn't notice any funny oder. Just drained and filled with regular ATF before I put in Honey and noticed no bad smell. Actually, I thought it smelled pretty good. I've never noticed a nasty smell from the MTL during the last 2 years of using it, either during fill or drain of old fluid.

Now my power stearing fluid, that REAKS.
