The people that may not now use it don't get the considerable benefit that it offers.

Those of us that have used it are left wondering what harm it will cause and who will pay for it. Ford must have found it harmful, why else would they have discontinued it? It certainly helps. My transmission is night and day better with it

Explanation please.

I'm not going to get too bent out of shape over this latest announcement.

I figure I have nothing to lose by swapping it out again.

As per current work shop manual and service publications, the XL-18 is no longer used. The mentioned chart has not been updated on the site since June (as per the bottom right corner of such: Version 3.7 / Published 6/2013).

You may all breathe again. I hope this helps.

Hey guys,

The change to the XT-11-QDC fluid occurred on 8/15/2011 the XL 18 additive began on 7/9/2012. Keep in mind that all manual transmissions will be more difficult to shift when cold and the transmission should be allowed to warm up bit (a few minutes of driving depending on the temperature) before attempting to shift the transmission aggressively.

The info I posted above was to clarify, the previous statements regarding XL-18 “must” be added when replacing the transmission fluid.

Once again, if you’re experiencing any concerns with your vehicle, be sure to visit your dealer for full diagnosis and let me know the outcome.
