Well I now have just over 60,000 miles on my 03 2.5 auto. I am starting to look into preventative maintnance. I would like to slowly start changing out all of the fluids in the vehicle. I dont mind spending a good amount of money for the best fluids, but I dont know what they are. Please list what fluids I can change and if there hard to do myself. Should I go by the old addage " if it aint broke dont fix it?"

 

Lets go guys I know you know the answers! lol

 

Lot of pros and cons here..But at risk of being chastized for my 35 years of automotive exprience...

I would have the dealer do the transmission fluid change at least..But the rear diff is not too tricky, and the transfercase is a bit of a challenge too as I'm finding out, but doable(read the threads below on the subject)...Engine coolant should have been changed a couple of times already (with Jaguar Anti-freeze concentrate)..the brake fluid should have been bleed at least every two years (I used Jaguar Brake fluid)...Power steering should have been replaced too with the Mobil brand Jaguar uses.

As far as what to use?

I would use top quality synthetic lubes and fluids in the transfercase, rear diff and engine oil as far as the DIY stuff.

Good luck.

 

would you guys recommend a tranny flush or no. I know its sealed for life but I just have a wierd feeling about not changing the fluid.

 

I would defer that to our Jaguar tech...But a simple drain and refill wouldn't hurt IMO (mind you,it don't exchange all the fluid that way, only about 2/3 gets drained) My Land Rover had a JATCO tranny as well and I drained it and refilled three times, driving about a 100 miles between each drain/fill.

 

For the brake fluid flush I second the ATE Super DOT4. I alternate on my Callaway 944T track car between the "Super Blue" and Typ 200 (gold color) that way you know when you have fresh fluid running through your line and not wasting it.

I am near 60k and looking into replacing my manual tranny fluid, tranfer case, and reardiff fluid as well.

Does the rear differential and manual trans require the same 1.75L of fluid? And does the transfer case, rear diff, and trans all have magnetic drain plugs?

Thanks!!

Sorry, I was unaware of the new ABS electronic spec ATE brake fluid. My newest car to date other than the Jag was a 1989. I assumed (my mistake) that when looking over my dad's 2004 Porsche 911 40th Anniv and seen that it had ATE Super Blueso I took it as that what was the factory fill and it has ABS, stabilty control, and suspension management systems.
Thank you for the info on the SL.6 ATE fluid. I will make sure that is what I get for the Jag when it comes time.

 

Real quick, if the rear diff has no drain plug how is one suppose to drain the fluid and replace with new? Am I missing something here??

The Amsoil Sever Gear 75w140 lube states it is compatible with most LSD units. https://www.amsoil.com/storefront/svo.aspx
Would this meet the need for Limited Slip additives or would I need a supplemental additive:

Thanks in advance!

 

Hey Chas...

The only way I can see to drain the the rear Diff would be to as our Jaguar tech said..somehow work a tube down to the bottom through the fill hole and suck it out with something..or remove the pumpkin shell and drain it that way...the first option seems easier as there is just about a hands thickness clearence to the suspension member just behind it..Either way, it looks to be a beotch of a lot of tight squeezes.[:@]

 

I do have a fluid extractor/replinisher which I used for putting gear oil into my Porsche transaxle (vs getting oil all over myself) so I will have to get under the car and take a gander.

Thanks for the reply!

 

Amsoil Steve would have been all over

 

The diff and t-case lube is a Ford spec # for synthetic 75w140 axle lube that is nothing special. Pick your favorite poison. As for the LS part, a friction modifier is requiredwith this lube if it's going in a vehicle so equipped, so I'm not sure why Jag calls it that.

 

Good to know, thank you for the footwork bojangles!
I find the huge variance in price between dealers interesting.

I spoke with an Amsoil tech rep and he had this to say: "AMSOIL SVG, 75W140 gear lube is the best recommended replacement for Ford WSL-M2C192-A."

Oh Jeesus..now I am confused...

From what I gather from Bo's post, any Synthetic gear lube (75w140)with LS additivesthat meets or exceedsLS requirements, such as Castrol, Royal Purple, etc..is not suitable for the X-type's differential..Is that correct?
