PTU hose down flush - what flushing fluid?

I'm changing my PTU fluid this weekend, wondering if there is a solvent I could put in to do a quick clean out (Seafoam)?

What model year?

Does it have a drain plug?

 

I prefer not to use anything else buy the normal operating oil to flush and then final fill.

Drained PTU got about 350 MLS, which doesn't seem like that much. A quart has 946 MLS in it. Fluid was dark and stinky but shavings were at a minimum. Used a magnet in the cup and only found very very small metal shavings.

my 2016. 2.0 shows the rear has 4 x the fluid capacity as the PTU.... too bad they didn't add more capacity to PTU, it certainly could use more IMO

If anyone wants to reference, here's a post I just documented my 2016 eco PTU fluid change.

Draining my PTU, exactly 400ml came out. Manual says should've got 530ml.

When filled, could only get 400ml in.

3.5L v6
