Be aware that too much modifier may glaze the friction plates and they start to slip.

Thanks for the post on "too much" lubegaurd VTL. I was wondering about that. Someone was talking about adding a little REDLINE after a full flush.

Yikes...I thought 1 bottle was, more or less, recommended or an 1 oz per liter of atf.

Mine started slipping slightly after about 4 oz into original 1161640 ATF, which I'm suspecting for having extra modifiers compared to other T-IV like ATFs.

Glazing is easy to fix: replace ATF, let HFM wear out. It is naturally wears out along with the friction material, and is replenished from ATF.
