we tow a certified used 2014 Fiesta with 30k existing miles, sister to the Focus, I purchased last year -
and now 32,000 of towing, just put it in neutral and go - no issues whatsoever
about a month after purchase, Ford had a paper out to dealers that explained a need for a update to the computer to solve some 'hesitation' issues, which we had done. I know that these 6 speed 'automatic' transmissions, like on mine, have had some issues with the 'grinding sounds' or 'hesitation', but the dealer said that they are actually designed to perform this way(?), and it does not impact the transmission or it's performance. I guess I've proved them right - 10k driving, 32k towing - and no issues.
