Synth is good for helping 'cold shift' issues but does nothing to help the syncros which need friction to work,hence the friction mod additive.Ford synth is way too expensive and a good brand of non Ford atf will do the job.The key to all these 'fixes' is the internals of the trans and the 'latest revision' levels of components.For example the latest MTX's in the Focus & Mondeo have many changes from transmissions fitted to current Cougars and even 'the last' Contours..my take on the whole tranny issue is the lubes alone will not save you from some of the early trans problems it just buys a bit of time.Ford would not have redesigned many of the internal components if it was not an design/engineering issue with this trans.At the moment I have 20 MTX's on hand and in repair in the shop...read into that what you will!
