Excuse my language. I have a buddy with a cummins who made the terrible decision of putting an ats trans in his truck. I followed him down to ATS's headquarters yesterday (150 mile trip for me and it was my fourth time down there for this same thing). Anyway this was the 5th time he had to take his truck to ATS for warranty and repairs. He has had 3 BRAND NEW transmissions from them. So we took a tech on a drive and showed him all of the problems... a couple recurring from the last trip down there even. Tech took notes and seemed to understand the issues. So my friend gets a call this afternoon saying its done. He triple checks with the techs that everything is fixed so we head back down there. Upon arrival, we drive the truck and NOTHING changed. Literally the exact same very apparent issues are still happening! Mike from ATS (who is a piece of ####) was an incredible prick and told my friend he was stupid and there were no problems and to "Get that #### out of your head". Mike honest to god walked away while we were talking to him mid sentence. Pretty professional. So my buddy said screw you guys I want my money back! And the other idiot, Jason handed him ATS's lawyers card. Thats when you know your company is terrible and tries to screw people. Be careful what you get from them. Im ashamed for them and will never go back again.
