Just changed mine this morning, took about 1.5 hours. Absolute piece of cake up till reinserting the fill plug while running lol. All my bolts and drain plug came right out with no issues.I do think it has been changed prior. (Not certain but everything came out to easy). Shifts better yada yada, I give this a 2 out of 10 in difficulty up until you start the fill process while car running, then a 6 out of 10 just for the difficulty in getting the fill plug started while exhaust is hot.
Thanks for all the tips in above posts!

Soooo.., did we ever figure out what needs to go back in? With or without the friction modifier? I'm confused.

I'm going to use a F-M, as it doesn't hurt if it isn't required. That, plus the word "clutches" I saw in that one post.

From what I have read so far there seems to be 2 different Gear Lubes, 2010 Shop Manuals shows one for normal Diff, Castrol SAF–XO 75W–90, and one for XKR E-diff Castrol BOT 720 75W–90.

EDIT: Further research found the Jaguar Part # C2D3650 and it is $36.38 so for $7more than the LR Fluid more I know I am getting the right stuff, plus you only need 2 quarts and it is not changed that often.

I would also assume this different E-Diff fluid probably has the Friction Modifiers, will read up more at Castrol to confirm (or not). So I am not sure adding more Friction Modifiers when the lube already has the recommended amount is going to be the best idea.

Hope that helps,

Dave

I guess I would need to understand if the LR diff is the same as the XKR e-diff. Somehow I don't think so but others should chime in with their knowledge.

Good point, I am sticking with the Jag Fluid.

Cheers,

Never mind about the LR fluid, after finding the Jag part number there is only $7 or so difference per quart and you only need 2 and rarely change it so it makes no sense to take a chance on the LR fluid. I edited the original post above to reflect this.

Just Chiming in on the need to replace e-diff fluid. My Jag dealer (Rosenthal Jaguar) actually included e-Diff fluid change for the 5th year annual maintenance ! Its a low mileage car. I thought this was actually recommended by Jaguar

I don't remember the exact mileage and don't have the receipt handy .
I think it was around 20-22K miles

Thank you for the info on fluid specs.

Do not fill the differential with lubricant up to the filler plug. The filler plug is only used to fill the differential with lubricant, and not to act as a level indicator.

Make sure the correct specification and quanity of oil is used.
So, we need 1.25l, but by reading this thread I get the feeling that I also need to move the back wheels?

One hint, since I was once on the receiving end of this...
MAKE SURE that the Filler Plug comes loose and EVERY system you will drain BEFORE you drain from the Drain Plug. For obvious reason, of course.

Also...

As a follow up on the Jag v LR E-Diff Fluid, I am confident now they are the same and ordering with either part number will net you the exact same quart of fluid.
The Jag part #C2D3650 @ $36.38 a quart is and the LR Part # is LR019727 @ $31.88 a quart , pretty silly for the same Quart of Fluid.







Happy Saturday,

Dave

Hi Dennis,

Hope you are doing well! I look forward to the time when we can get together and talk XK.

I haven't notice an issue with mine, but I have no record showing it had been done, it just makes sense to do it.

Enjoy this beautiful weekend we are having, sure is nice outside!

Cheers,

Dave

Trans and e diff change. I called Jaguar in Tampa today to see what they would charge me to change the transmission fluid and do an E Diff change. It took some time for them to get back with me and they told me they were both closed systems. I asked, what if you had a transmission leak? They said they would replace the gasket and the filter and put in about 8 quarts of oil at $60 a quart. He said there is no scheduled maintenance change for either of those areas from Jaguar. He said that if there is a problem with either one of those, they normally replace them. I told him, that’s not a great option if you’re an owner who’s car is out of warranty. Hey said, I see what you mean. But I checked with the master mechanic here and that’s what he said.
So my question to the forum is Jaguar says neither one of those should ever need replacing. How do you feel about ? A partial tranny change by dropping the pan replacing the filter versus a complete flush? (for a car with 67k) In the old days they said to never do a complete change. My Jag has 67k miles and my was a preventative measure.
What are your thought about this unspoken maintenance need?
2. And if you moved forward, how do you know how many qts does it take for a full change vs just dropping the pan and doing a partial? And how do you check what is in there? Thanks

Hi Dennis,

Watch this video direct from ZF, should be the last word on this. Tampa Jag should watch this video.

While informative, that video was painful to watch.
