Old punk, my experience with transmissions has always shown that if the old fluid is black, there is a high possibility that it had metal fragments in it which we're wearing down the transmission. It happened to my jeep and I ended up having to pull the transmission. I honestly think that you caught your car just before the second gear synchro went out. I would recommend not waiting to swap you xcase fluid. It will really come back and haunt you if there isn't any fluid in there. Just my two cents!

 

Speaking of the TC, gonna do that tomorrow. I picked up a bottle of Mobil 1 SuperSyn 75/140 LS synthetic gear lube. The local auto shop had Royal Purple but only 75/90 and I thought I remember someone saying the weight was more important than the brand.

Anyway, will this stuff suffice or should I try and get the Royal Purple or Redline? It says it meets API GL-5.


Thanks

 

Yeah, your stuff that you got will be just fine..If all goes well, do it again in about a 1000 miles..that way you'll get a good flush.

 

I have a 2005 x-type 2.5L manual.
I have inquired about exchanging the transmission fluid before at the dealership and they have told me that the transmission fluid is sealed for the life of the transmission...is that true?

Your directions look super easy and I will definitely do it if I shoud...at what milage is it recommended to exchange the transmission fluid? I am now at 70,000.

 

Reid, basically everything that Jag tells you about anything being "sealed for life" is false. Their "sealed for life" xcase, tranny, and diffs all need to be serviced just like a normal car. I personally think that Jaguar was just trying to save on warranty maintenance and didn't have to space to put in a conventional fill valve on all tree components which lead to their "sealed for life" ploy. If you have 70k, I'd swap it out because it's super easy and could even save you a headache down the road!

 

thank you...that is good to know. I will definitely follow up with this fluid exchange this summer. much appreciated.

 

I did this today, should have done it sooner, shifts smoother now. The hardest part was waiting for the oil to flow down the hose into the trans ha. Now I want to do the transfer case, and has anyone done the rear diff?

 

Justin, that was the worst part for me too. It was a real slow flow for me as well. Transfer case is a bit more involved as it doesn't have a fill valve and only has a drain. To do the xcase I just went to the hardware store with my drain plug and found a fitting that would fit in my drain plug that had a nipple valve on it so I could run some nylon tubing to the drain valve. This is also very nice because you can see the xcase oil level through the nylon tubing.

There is also a write-up on here on how to do the diff, but it is basically the same as the xcase. Once you find the drain valve, you just create a fitting, run some tubing to the fitting, fill it with oil, check the oil level from the nylon tubing, and then put back in the drain valve before you lose all the fluid you just put in.

Some people have replaced the drain plug with an actual permanent valve so they can just close the valve on the drain and not have to deal with losing fluid, but these valves don't have a magnet in them so they cannot remove metal fragments like the original drain valve.

Just my opinion on lubricating all the "sealed for life" components.

 

despite the complications of draining and filling a jaguar I loosened the torque converter and dropped the oil pan so that I can get to the plug. I finally get the plug off and use a siphon tube to fill her up but for some reason as soon as I siphon fluid into the box it comes right out! I'm not really sure what I'm doing wrong or if I need a special tool, please help.

 

Sounds like the Wrong hole....You do know that this is a manual Transmission thread right...find an Automatic transmission thread (dozens) on draining and refill.
