I just drained my 2011 XKR transmission. I was only to get 4 1/2 iters after letting it sit for a day.
I did empty it when it was cold
I've read that it's supposed to take 5.2 L to fill
Is it supposed to run out the drain plug when it's full? I don't want to overfill.
i'm going to fill it again when it's hot.

 

Are you letting it sit with the sump/pan removed or with just the drain plug removed? You need to unbolt the sump to change the filter (integral with the sump) and get the maximum fluid out.

You can only refill it to the correct final level with the new sump/filter bolted into place and the engine running and the fluid between 30 and 50 degrees C.

I don’t have the manual with me at this moment. Both the ZF manual and the Jaguar manual have very clear instructions.
As suggested by @RichardS , proper instructions must be followed.

1. with the engine (and transmission) at proper operating temperature, and with the engine running! And the transmission in Neutral, Fill via the fill port until the fluid starts to drip from it.

2. following the change, there are specific instructions running the transmission through its gears, then as above, checking the fluid level again.

3. The ZF manual is readily available at zf.com.

I personally don’t understand changing fluids without changing filters. Dirty filters result in reduced fluid flow.

I took off the pan to drain. I'm going to run it again until it is warm. I will then add to it slowly until it flows out the fill plug. I've gotten back in about five. I like the idea of drive and dump two more times to dilute the old fluid in the torque converter

 

Is it the first time that the fluid has been flushed? Man oh man, the task of getting my fill plug removed was an absolute adventure.

 

Yes, it was 48K miles. Wait until you try to find the differential fill plug.
I have a trick get a 8 mm Allen wrench cut the short end to about a half inch and the long end to about 6 inches and you could get in there
It is still a challenge

 

Thankfully for me, finding/draining/refilling through the plug on the diff was at least 10x easier for me, but not without reason. Not entirely sure if the diff oil had been changed and/or when, if it ever had - but the transmission fill plug had never once since factory been removed. 18 years in place, 100k miles of pure stuck. As black as oil can get. Broke an open-ended wrench straight in half trying to torque the plug out. I know the fill plug is rather girthy, but I would have swore that it'd strip the allen in the fill plug or break the fill plug LOOSE before it ever would break my wrench. Ended up having to drop the exhaust to get the absolute best handling on the plug that I could. This is all while the car is on jack stands - I don't have a car lift at my disposal. It was a nightmare... but now that it is done I can do the job again sometime and not die over it lol.

Glad you got it all sorted, if you got it all done.

 

Can we get a video tutorial on how to change the transmission fluid and differential fluid on the X150 Please?That would help out a lot of us XK owners for those of us that like to DIY

 

Jonhenry I have a small suggestion to make. After dumping the 4.5L of fluid, don't warm up the rest, before adding. Suggest you add, then warmup the fluid.

 

Yes that 8mm fill plug is extremely tight from the factory and it took a heck of a lot of force to break it free. So before doing anything to the transmission be SURE to loosen that plug. We have had people who pulled the pan and drained the fluid out and then tried to remove the fill plug but could not.

I also use a cut down 8mm 90 degree Allen wrench but did find that Jaguar and JTC do make a tool for this. As you might imagine the JLR tool is much more expensive than the after market version.





Jaguar JLR 307-452 or JTC 6878.
But it does seem expensive for what you get and the price does vary from $40 to $80.

For me, the trouble with videos is the interpretation of the point by point instructions provided in the manual... Assuming nothing has been missed or added.
A paper based, ordered check list is my go to. I print out the pages from the manuals for any operation.

Agreed, those plugs were tight. Nothing some penetrating oil, the right sized tool, and a breaker bar can't handle... I think it was "cracking" the original sealant that was the issue. I hate that stuff.
