Scanning old Ektachrome

I am scanning some 35 mm Ektachromes which my grandfather shot in 1956. As you can see from the attachment, the colors have faded and, possibly shifted (Is that the right term?). I have a copy of Photoshop Elements which came with the Epson V700 scanner that I am using. The Auto Color Correction option on the "Enhance" menu helps somewhat.

Is there anything better?

I would go, after in PSE, go to enhance and reduce to 8 bit, and then find color cast and try to find something that would be white in the scene and then click on that to get something close and then further tweak.

Frankly I'm a little surprised at the color lose. This really seems extreme.

Here is a version I ran though a program I have for this. But this is probably a very under exposed slide with a lot of time poorly stored, this is what I got from a quick rework.

You probably won't be able to color correct to any acceptable degree. The magenta, cyan and yellow layers fade at different rates creating something you can't correct. You probably will get good results if you scan them as B&W or convert to B&W.
 
This is what can be done with just two clicks of the mouse with Kodak Digital ROC & SHO plugins.

I'm still flummoxed by the way your Ektachromes have survived. I have many many that are as early as yours, but this is from, (it was easy to find), 1964:...

There is a MASSIVE difference in the dye stability between the Ektachromes of the mid-'50s and those of the early to mid-'60s.

Most of my family slide collection shows significant color fading and/or color shift in all E-2 class films, Kodak and others, that were shot in the '50s. By the early '60s the films became more stable. Pictures from 1962 onward in my collection show little shift. Kodachromes show very little or none all the way back to my earliest from 1948, and those are Kodachrome dupes as my mom's uncle kept the originals from that set.
 
Here's what I get from your example using levels and curves in Gimp.

I've done scans of 70s vintage Ektachromes and had reasonably good results, on both those which have faded to magenta and faded to cyan.

Your example appears to be very weak on the cyan side. I tried to compensate by bumping up the green saturation but it had very little visible effect. The best I seem to be able to do lacks any blue in the sky and still leaves the trees dark greenish-grey.

Each successive iteration of the Ektachrome process, ending at E-6, improved stability, but of course storage conditions and processing quality has a big effect. Some finishers used reduced wash cycle length or exhausted stabilizer. E-6 processing is relatively simple so was carried out by many labs and individuals, with varying quality.

Kodachrome is an entirely different animal, complex enough that few labs beyond Kodak's own could process it. The resulting transparencies were far more color-stable, especially when dark-stored than were Ektachrome of any variety. The dye layers of E-films are incorporated in the emulsion at manufacture, whereas Kodachrome consists of color-sensitive individual monochrome layers that are dyed with very stable dyes.

I agree here with processing... most my Dads Ecktachomes where done by Kodak... those held up better than those at local labs...
He also shot Ansco Slide film, in the 60's, they seemed to fad more to the blue side...

Kodachrome's held up very well...

all where stored in closets in a air-conditioned home, and later after his retirement, in boxes in air-conditioned indoor storage units.

You are probably right; here is a 1937 Kodachrome from my father-in-law straight scan:

and just color correction with PSE;

Also, just a few years later from him again in 1941; Kodachrome (straight scan):
