2013 Ford Focus cruise control problems

erratic shifting and eratic slipping gears , first happened while on highway and then it wouldnt go in any gear besides reverse and would say transmission overheat wait 5 min . caused another veihcal behind me to slam on there brakes and they ended up getting rear ended from the car behind them ..... all becouse of my cars tcm or transmission issues>!!!! also not too mention ` random unusual noises coming from clutch or shifter when not even start car yet _delayed start and delayed shifting ..

May 0f 2015 on a highway car lost power even though I did not take my foot off accelerator then it bucked back and forth as I made my way to breakdown lane took it to ford service and no incident was reported in computer. Car had given me the message "engine fault service now!". This has since happened in sept., october 2 times, december and now january 2016. Ford has refused any action or compensation. Dangerous situation as car slows right down and could cause bad accident. I have 2 little children.
