My dealer just did the TSB11-11-1 on my 2012 Mustang V6 because I was having issues trying to get into 1st gear. This TSB in Canada replaces the transmission fluid to XT-11-QDC but doesn't include nor have they heard of the XT-18 Additive. This TSB has improved my shifting greatly but I'd like to have this XT-18. Anyone know anywhere where I can order a bottle?
