Ok...I have had issues with Ford drivetrains in the past and recently...CD4E Transmission (Google it)......on my third such tranny on a 2006 Merc Mariner 4WD with a mere 70k miles...had it from new...no towing no abuse...have a 2006 Ford Explorer 4.6 V8 4WD that is showing signs of transfer case issues...had it from new no towing or abuse...I now have my hot rod stock 2015 SHO non-PP got it new and I am reading these PTU horror stories....my SHO has just over 10k miles on it..I will say I hear a suspicious drone noise seemingly from the front end at speeds below 30mph but I have put it off thinking it is just tire noise....So I am wondering if Ford actually did anything to correct the 2010-2012 SHO PTU issue or just added a drain plug and drain interval? I am guessing I am best off changing this fluid asap and the every 10k miles? Any advice and direction would be appreciated ...and I buy Fords because I am loyal and used to be an employee....so I get them cheap..I know u gotta be asking the question...I keep asking myself the question....but when one gets 20% off sticker it is an easy answer! Thanks
