Hi all, I'm planning to do a Transmission fluid and filter change on my 95 3.2lt x300. Since I purchased the Vehicle about 18 months ago, I've been systematically working through all the periodic maintenance
Although the service books have all the stamps, they are very lacking in what has actually been done.
Can anyone point me to an existing post on the procedure for a transmission filter and fluid change or add one for me.

 

1st step is to determine if your xmsn pan has a drain plug; some do, some don't.
Many of us drain it and refill with new at each engine oil change, thereby gradually freshening the fluid. If memory serves, I believe you get about 3 quarts+ that way. But there are valid reasons to drop the pan after some miles even if you do that as can be seen in the link: https://www.jaguarforums.com/forum/x...-fluid-149399/

 

As said.

If no drain plug, simply loosen the fill tube large nut, and let it drain. Retighten that nut (FIRM, not stupid tight), refill the transmission, do it again in a month or so. It will take about 8 of those drop and refills to get the concentration levels back into the 90% range.

The filter inside is a mesh gauze filter, so changing it is not required.

IF, when you drop the first lot of fluid, there are "metallic" bits in it (very strange for the ZF 4HP22), then the trans has issues. But, as I said, very strange for that trans to have issues.

If the urge is there to drop that pan, it is simple enough, but time consuming, AND, those small retaning bolts are sooooooo easy to crossthread. Done that.

I use Penrite Multi Vehicle Full Synthetic Trans Fluid in all mine, never ever had any issues. The TH400 and the ZF are so sweet now with that fluid.

 

Would a MightyVac through the dip stick tube work well to drain the pan?

 

Probaly.

I am seriously physically challenged, and getting down and undoing that fill nut is simple enough for me, and it does allow most of the fluid to drain. Not sure how much that sucking method would leave behind?

 

Thanks for all the advice guys, I've purchased a 5-liter bottle of ATF MULTI VEHICLE DX-III AUTO TRANS FLUID and am going to tackle it tomorrow. The penrite site states that the transmission holds 4.3lt of fluid, so I will see how much I get out of the drain plug.
I've also already purchased the replacement filter and gasket, so going against my better Judgment will also drop the pan and fit the new one after I've taken it for a decent run.
Hoping all goes well and think in future I will take the advice of aholbro1 and Just use the drain plug and top up at every Oil change.

 

Good on ya.

I have never found a transmission or power steer system that complains of regular FRESH fluid.

 

....well, I haven't used a MightyVac with the Jaguar XJR specifically yet, but I've used them many times on other cars and it works great. It pulls just about as much as draining if used correctly, and you can measure exactly how much fluid is removed so you know how much to replace.

This really saves a lot of time and mess by not having to raise the car, drain the fluid into a catch, open a drain plug, risk crossing threads, not properly tightening, etc... Of course depending on what fluid is being replaced, and any need to change a filter, you may still need to get under the car and deal with a leaky mess. But for refreshing the fluid itself, the extractor makes life really easy.

If one isn't sure all the fluid is removed or equivalent to draining, the process of using the extractor repeatedly over time will guarantee most of the old fluid is gone and refreshed with new.
