Does anyone know if this is the right fluid for my 2009 XKR 4.2? It says for the XK but I'm not sure is the missing XKR is an oversight. I bought my XKR a month ago and just want to get the fluid changes baselined.

Also, do I need to replace the mechatronic sealing sleeve too?

Yes, that is the correct fluid, ZF Lifeguard 6. Yes you should always replace the mechatronic sealing sleeve when changing the oil. The pan they are using is the ZF pan so all should be good.

 

It's an easy way to buy, but not quite double what I paid for a pan, sleeve and 12 quarts of SPEC fluid on Amazon. Oh, and six quarts won't be enough. Mine took 9-1/2 quarts on a pan replacement.
I got the pan and bolts for $42, the sleeve for $9 and the case of fluid was $92.
Of course, it is easier to buy one thing than three.

You really will need more than that six quarts though. It'll be a pickle if you get it drained and don't have enough on-hand to fill it up.

What I bought:
Pan and bolts at Amazon


Not the exact one I got, cuz zero balance;
Sleeve at Amazon

Spec Fluid at Amazon
According to the Australian Petroleum Institute: Key To Lubricants their ASP15 classification includes the following fluids:
-Ford Specification No. M2C 919D
-Mercon SP Fluid Part No. XT-6QSP
-Shell ATF M-1375.4
-ZF 6-speed Automatic Transmission Fluid, (Shell M-1375.4)

Mercon SP Fluid is a newer transmission fluid made by shell for Ford dealers. Its easy to find online, and it retails for around $4:00+/quart. Things get really interesting when you look at the specs of lifeguard 6 found in the MSDS:
http://www.tsgparts.net/images/pdf/Lifeguardfluid6.pdf and compare them to the specs of Mercon SP:
http://www.fcsdchemicalsandlubricant...ERCON%20SP.pdf and http://www.fcsdchemicalsandlubricant...us175325us.pdf

Yes, some people will yell and scream because the fluid "isn't OEM, DAMMIT!" Well, too bad, it meets specs and is 1/3 the price of the exact same liquid in a different bottle that has a fancy label on it.

 

I appreciate the fast answers.

 

Are these also good for the 2010 and up 5.0L XKR tranny?

 

If it has the 6 speed transmission, then yes.
