I think there is a lot of confusion. MB and Chrysler developed ATF+4, and used it as PSF, as far as I know. That means any good ATF will substitute. BUT mixing ATF with Pentosin means disaster, they are the one truly incompatible fluid combo in auto industry.
Best method is to smell or inspect the current fluid. Red and smelly = ATF
The following product list should help you to select the correct operating fluid for your vehicle/major assembly from the variety of products in the market.
We are recommending to use exclusively the products listed in the following overview, because only these products have been tested and approved by Mercedes-Benz.
We recommend using only products
which are distinctly marked with the label indicating the approval of Mercedes-Benz, e.g. “MB-Approval 229.51”. Labels referring e.g. to “MB 229.51” don't have an approval of Mercedes-Benz.

It looks like CHF 11S or similar "synthetic" PSF is required. My 2007 had ATF in the reservior, so kind of confusing. I have to flush it back to CHF 11S, and do it completely as the fluids are not compatible. Not "miscible", they don't dissolve in each other and cause poor lube conditions. It will kill the system.
