My 2002 XKR coupe with the Mercedes 5 speed auto has hit 95,000 miles. Front oil cool lines and power steering replacement line arrived and await install. Since I am going to keep this car, I'm wondering when I should have the supercharger oil replaced and the rear differential fluid changed too.

I saw a thread where someone showed an easy way to do the s/c change that was a surprise to contributor Rev (he of the flying bird in front of his XK8 convertible).

Getting an LSD is probably never going to happen for me, but since I'll be putting in a larger rear anti-roll bar, I'm wondering if the differential fluid should be dealt with too.

 

Both should be changed sooner rather than later.

Don't forget the ATF either. Merc now has a change recommendation at 60K.

 

I changed my ATF at 40K; it was 10 years old so I figured better safe than sorry.

I had the transmission fluid done with an oil change about 2,800 miles ago. The transmission fluid change solved an annoying low speed groan that I hated to hear in parking lots.

The supercharger fluid change efficient method I have some details on.

The rear diff fluid change does not look fun or efficient. Anything I should pass on to my mechanic?

 

He will need a tool like this below, see this thread https://www.jaguarforums.com/forum/x...iff-oil-71492/

 

next time i have the drain plug out, i'm going to epoxy a piece of 1/2" square bar stock into the drive recess of the drain plug

no more fiddling with adapters that drop out into the differential A frame

 

Thanks!
So, is switching the transmission solinoids to the "blue tops" worth doing too? Are my existing brown solinoids at diminished capacity after 12 years and 95,000 miles across 4 prior owners?
