Would someone kindly share the repair manual page for replacing motor mounts?
I am pretty sure I need to do mine and don’t have access to my e-copy anymore. Am thinking there are two mounts for motor and probably at least one for transmission. May as well replace them all at same time right?
Also, has anyone come up with alternatives for the mounts (other than from JLR?) I’d like to keep the car as OEM as possible but am not sure I need a mount that will last another 115k miles (the car will be dead by then I’d guess.) If one costing half of what JLR charges lasts 50k miles, I’d make that trade.
Thank you in advance for the help. Or…the guidance if you tell me that I’ll regret getting a second-tier mount.

I had posted about this recently. The rubber Hydro part is starting to perish and there are signs of leaking below them.
Two motor mounts and one transmission mount.
I got all three for $190 from IBSpot.
Caveats: I have not had them installed yet. Which will be $800. They are for another model but the same part and all of my research says they will fit.
I looked into installing them myself. No go for me.
Blockers:
I do not have extra jacks or a lift. You need to support things while the car is on jackstands. I don't trust myself to do this properly.
For the trans, that's obvious.
The driver's side mount requires you to support the steering rack. Could easily go south for an amateur. Not willing to risk it.
Hope that helps!

Yep, @Bill400 , I was also unable to find anything on the 4.2L install. I'm fairly certain is is very similar but the mounts and brackets are different so there may be variation.
To further expand on my purchase above, I had done extensive forum research and my JagX150 LLM (not your run of the mill AI) confirms 90% chance the XF mounts I bought will fit.
Parts I bought: 2009-2013 Jaguar XF and XJ 5.0 and 4.2L part numbers C2P17845 and C2D38505
Analysis:
Engine Mounts:
Your X150 4.2L OEM: C2P20052 (superseded from C2P8855; no further supersession found).
Part (C2P17845): OEM for 2009 XF 4.2L and 2010-2013 XJ/XF 5.0L; also listed for 2010-2015 X150 XK/XKR 5.0L models in some catalogs.
No direct supersession from C2P20052 to C2P17845, but they share the same Ford/Jaguar Worldwide Engineering Release System (WERS) code (6W83-6A003-AE), indicating identical physical design across 4.2L applications in XK, XF, XJ, and even older S-Type models.
Transmission Mount:
Your X150 4.2L OEM: XR849534 (superseded from XR837771; no further supersession found).
Part (C2D38505): OEM for 2009-2013 XF/XJ 4.2L/5.0L; broadly listed for XK/XKR (including X150), F-Type, XJ8, XJR, and Super V8 in aftermarket catalogs.
Some sources confuse it with rear engine mounts due to similar hydraulic design, but it's specifically the rear transmission support.
I obviously will not know until my Indie installs them early next Spring. But I'd say 90% confidence level is pretty good.
The workshop manual for the 5.0 is the same from VIN B32753 0nward. Differences are minor if any and certainly the engine mounts instructions are the same.

Update: headed home down a dark side street, emerging onto a major road...and you all know where this is going...drove smack into a curb that wasn't there a month ago nor was it marked...yet, it was built right under a traffic light and didn't have signage/painted lanes indicating you must go left/right and not thru. My poor front spoiler is no longer with us and the under tray is somewhere on that road.
Yeah, I am beyond annoyed at myself.
Off to Marketplace to find me a new front bumper cover, lower grill and trays. If anyone has spares for a facelift XK, I am a ready buyer.

Very sorry to hear of your misfortune.
In case you are not familiar, there were two "face lifts": 2010 and 2012.
The under tray for the 2010-11 is different from the 2012-15.
The chrome trim and side reflectors (all of the small parts) should be salvaged if you can find them.
Everything is quite expensive, not available and/or hard to find.
