Sport RDU oil change - what's the true capacity?

2017 Sport with 28K miles.

 

Today I did a lube service, changed engine oil, PTU and RDU.

 

I've done a few PTU oil changes, so its expected that its oil still looked very good, and the first oil change on the RDU, which also looked good (yes I know, its way early for t he PTU and RDU).

 

I had to extend my oil extractor using a small silicone tube, but still got less than a quart out of it, and it took just less than a quart of Red Line 75W90.

 

The owners manual states 2.4 pt for the RDU - is there a special technique to extract more?

 

Also, the manual lists the PTU capacity at 11.8 oz , and I add about 85% of a quart jug.

Check online for the latest revisions, I believe it was 24 oz for the PTU last I saw. They have a handy dandy HTML version now!

Where is the filler/dipstick for the automatic transmission on my 2018 Edge Sport?

Is it under and hidden by the aircleaner ?

Not directly below the air cleaner.

 

See attached photo - its under the pipe below the red dot.

 

Going to be a helluva task to check it with the engine running and hot.

These capacities are consistent with the html version of the manual for my 16 as well. I find it interesting that even the most current printing pdf version has the old quoted statistics on it. It seems such an easy thing to edit and recompile for accuracy sake. These updated statistics also verify what MACT has said previously about the increased fluid capacities on the PTUs.
