Hi all, i managed to get my hands on a Jaguar XF 2.7d 2009 Model with 142 000km. It was an auction car so i have no idea of the cars history except that the previous owners really should not ever get a car with a cream interior again.... stripped out the entire interior to deep clean carpets and clean the leather and all other interior panels.

Anyways, i want to keep my kitten purring nicely so im going overkill on the maintanence for this car.

Changing all fluids on this car

-coolant
-engine oil
-diff oil
-gearbox oil
-brake fluid

also going to do dpf and egr delete with remap and also all belts including timing belt.

Anyways on to the problem at hand. i watched many vids on changing the gearbox oil and filter pan.... im not satisfied, that new oil is mixing with a bunch of oil hanging around in the torque converter! noooooo! so my question is how can i bleed the oil out of the torque converter? is it like the old boxes that you can connect a pipe to the return from the cooler and put the car in drive so that the old oil pumps through the torque converter? i wont be able to sleep if i know i got 50/50 bad and good oil in my box..

 

I'm pretty sure the only way to get the oil out of the torque converter is to drop the valve body. I'm getting a trans service done on my 145k km 09 XF next month. I'm only going to get 6 of the 10 liters out of the transmission. I'll just have to live with it.

 

This is a topic of great interest for me, as I'm really big on maintenance. I've owned General Motors vehicles for a LONG time, and I'm used to automatic transmissions with dipstick tubes, that you use to refill the transmission. So I'm used to changing transmission fluid/filters on a regular basis, with no hassle.


The Lincoln LS, that we had previously, to our XF, was also supposed to be a "sealed" transmission. However, there were two recalls for transmission upgrades/issues during our ownership, and when I spoke with the dealer's service manager, about scheduling a fluid/filter change, a couple of years before we traded it, he advised that since the fluid/filter had been changed as part of the earlier service visits, it wasn't really necessary. My Jaguar dealer's service manager says that a change isn't really necessary.


I find this hard to believe, as the "inner mechanic" in me says that there's no replacement for good maintenance. A couple of folks have posted on this website, "transmission fluid/filter packages", which consist of 6 quarts of tranny fluid and a replacement pan/filter. I'd like to do this maintenance, but since I don't have access to a lift, where I can easily work under the car, I'm reluctant, since I am aware that the fluid level needs to be checked while the car is warmed up and engine running.




Does anybody know, for sure, that the transmission needs all 6 quarts of the fluid that comes with the "kit", or is it 5 quarts, and a little more, not quite 6? My point being, if I got the car up on my ramps, drained the tranny via the drain plug, dropped the pan/filter, pumped 5 quarts of fluid into the tranny, placed my floor jacks under the right side of the car and "tipped" it just a little, slushing the tranny fluid to the side away from the fill port, then pumped the additional quart into the tranny, would that work??




Any thoughts??

 

Youd have to measure how much oil came out of the tranny but you should be able to drain 6 quarts and then add back 6 quarts. The rest of the fluid will be in the torque converter and you won't be able to drain it.

 

Drop the valve body and let it drain over night. I got close to the 10L doing that.

I also installed a Sonnax Zip Kit while I had it out, and replaced all of the plastic/rubber pieces in various places with new ones.

 

i wanted my mechanic to do this but I don't think he had any interest. So I'll just have to settle for the 6L change.

 

Gentleman, i found the solution. there are service shops that have a Wynns transerve mega flush machine that properly flushes your gearbox. you just have to figure out who has one. i found a land rover specialist in our country that has one, he is a bit far away but its worth it so im gonna go there.

you guys can check a vid on how the machine works on this link:

 

Interesting, BUT........this process doesn't replace the filter.

 

If anyone located around Toronto is looking for some Mercon SP for their trans service feel free to PM me. I have 10 extra quarts on hand.

 

The car needs to be level when refilling the procedure is explained here https://www.jaguarforums.com/forum/s...plained-37802/

 

When I did mine.

Definitely need to follow the proper fill method, rather than measure the amount.
