Here is some interesting information: A big thank you Haz for this! Power Transfer Unit - Description and Operation - 2.7L EcoBoost - 2022-2024 Edge Workshop Manual.pdf

This is from Ford: It applies to the 2022-2024 ST There are two different models of the PTU. The low torque PTU is paired with the 8F35, 8F40, and MMT6 transmissions. The high torque PTU is paired with the 8F57 transmission. The low torque and high torque PTUs are similar in design and operation. The ST has the 8F57 transmission

Thank you chr8990 for the pdf on the ptu/rdu. I believe the ST's use a high torque ptu ? Other than a cooler there must be some stronger internal components.

garycrist. do you have a recommendation on what fluids to use in the PTU and RDU? I know they each use a different fluid and there are some good choices including the OEM. I have heard about Redline shockproof for the PTU and not sure about the RDU. Thanks for any feedback.

From what I know is you definitely want the PTU and RDU fluid changed. I would make sure that the dealership actually knows what you are trying to get serviced. Seems like some of them are in the dark on the PTU fluid change as it is not listed as a routine service. I think the transmission could be at a later time interval but not sure. I too would like more info on this as I will be taking mine to the dealer when the time comes for me.

I can't speak for all models, but my 2024 Edge ST did come with the for/aft up/down headrests. The driver seat is still 10 way but the passenger is now 6 way adjustable. Used to be 10 way on my 2021

A very big thank you, Haz. Not the first time you have helped me out. Very much appreciated!!

Well an update- I verified the noise we are hearing is coming from that side of the vehicle where the rear cargo vent is. I verified that it is 100% speed related and most likely wind too. I don't think it is related to the seatbelt, but possible the fuel fill/door/compartment. It doesn't seem to be there when everything is cold. I also seems to be getting worse- as in happening at lower speeds. I am tempted to pull that drivers side rear cargo area trim panel off and have my wife drive while I sit back there again. I am not sure exactly how that trim panel comes? Looks pretty basic. As for my other little rattle- seems to be coming from the cargo hatch, down by the automatic locking mechanism. I will have to do more research.

Never go aftermarket. Go OEM and you won't have issues. I know this from experience.

Thank you Haz! Much appreciated. Jim

Ok I have a 2024 Edge ST. For some reason I could not find it in the digital owner's manual in the vehicle, but I will check again. Sure miss the 'old school' printed manual ! Thanks for the help

OK. I am going to use Amsoil for both. But are they different? Which one do I use in the RDU? PTU? Thanks so much guys for all your help.

Just curious to know what fluid is used in the RDU and is there a better aftermarket alternative. I plan on doing mine soon. Also the same question for the PTU. I think they are different fluids???

Thanks for the clarification. Based on that, my 2024 Edge does have hill start assist. It does not have auto hold. I am positive that my 2021 also had the same. It seems like there is some confusion regarding auto hold which is a physical button and not an option on the Edge?

I can confirm that my 2024 Edge ST has auto hold. I can't remember how to turn it on and off, but it does exist. It also was active on my 2021 Edge.
