w102acd Posted 19 hours ago Report Share Posted 19 hours ago All, I'm looking to service the rest of my drivetrain on my 2019 Edge ST. I did service the transmission several months ago so good to go there. It looks like the PTU needs to be sucked out of the fill and replaced with 12.7oz of 75W-85. It looks like the RDU has a drain and fill plug and replaced with 28.1oz of W75. Dumb question: Does this vehicle have a transfer case? I can't seem to find any details on it if it does. I have a 2020 Explorer that does have a transfer case that I'm going to swap the fluid on. Thanks! Quote Link to comment Share on other sites More sharing options...
fishx65 Posted 18 hours ago Report Share Posted 18 hours ago No transfer case, the PTU handles these duties in all wheel drive vehicles. Quote Link to comment Share on other sites More sharing options...
