I have an 04 XJ8 (30,000 miles) .
I noticed a small puddle of clear fluid on the garage floor today, had the car put on a lift and noticed some of the same around the rear of the tranny pan, wiped it clean and dry, did 100 miles, re-checked and it had stayed dry.
I read on here( and from other make forums that use this same trans) that the sealing sleeve can cause intermittent leaks, is this my most likely culprit?
I cannot see the source of leak.
Is it possible to replace the sleeve without removing the pan?
If the pan is removed for any reason should it be replaced with a new one ( I see the filter is built in??) and new gasket.
Is a special tool needed for the filler plug removal and should that plug be replaced, or is there a seal ring on it?
How is the new fluid put in, is there a filler tube available?
How is the fluid level checked and topped off in the future?
Thank you
David

If it was clear could it have been water?
Obvious sources would be condensation (such as cool weather overnight), rain, a/c.
If it happened to me I'd rub it between finger & thumb (oil is quite distinctive) and - wait for it - taste a small amount. You will know if it's oil, and no it won't kill you
No jokes about spit or swallow, please!

Most likely from the A/C system, original ZF fluid is golden in color.

Yes, and it is visable when getting underneath the vehicle and looking where the electrical connects.
Is it possible to replace the sleeve without removing the pan?
NO!

Somewhat cheap insurance, your call.

Read the beginning of this thread or read this one: https://www.jaguarforums.com/forum/s...joycesjag+saga
How is the new fluid put in, is there a filler tube available?
Again read above.
How is the fluid level checked and topped off in the future?
All covered above.
Thank you
Your welcome

Thanks for the responses.
It was def tranny fluid(about half a saucers worth after sitting in same spot for a week), it was visible just in the rear corner passenger side of the pan for about 3 inches around the pan bolt area;once dried and driven for 3 hours it stayed dry, that seems odd, can a leak be that intermittent?
Finally, it seems odd to me that this transmission has no way to check levels without going through this pian in the *** procedure, how much would a dip stick and tube have cost?
I know in the handbooks that Jaguar says "no check/top up required" which is fine till it leaks and then the owner has no idea what the fluid level really is.Evidently, from what I can see, there are no warning / check lights for low trans fluid, just a limp home mode for when it breaks.Seems risky with such an expensive item.
PS,
Should the filler and drain plugs be changed out too, or do they have seperate seal rings on them?

Yes, mine and member ccc did! Its the rubber sleeve that needs replaced.

Apparently to much, especially for a $65,000 vehicle.

All replaceable gaskets come with pan not including the rubber sleeve.

YES! My leak was intermittent and would drop about 100 ml every now and then. Say once every 400 miles. The problem is you don't know how much fluid is left.

I get a small patch of wet under the car (S Type) it;s condensate off the air con. system and it's nothing to worry about, It takes a hell of a time to dry up. My previous X type with a manual box did the same. It is mentioned in the car handbook.
IF it's tran. fluid, that is cause for concern, a small puddle of clear water is not.

Some additional pictures comparing the old and new sleeve (the old red one came out without any friction, the new one had to be pressed hard to replace. Another photo showing the difference between the old jaguar pan and the new zf part. One showing what the transmission looks like with the sleeve removed. Last two just shows where to jack up the car. The second pair in the photo is just a backup and doesn't touch the car.
I'd like to know so I can backflush mine as I took it off today. One thing I came across was if you use a heat gun on the end of the pan bolts the 27mm torx ended bolts come away fairly easily. They need force but you hear a crack and then they are free. I am not sure if the replacement bolts have loctite on them but the ones I removed today certainly did. I am going to replace all of mine with 6mm hex bolts plus a thick washer.
