Yes maybe I missed a few things this site can be confusing at times, could be my old computer to. I didn't see Don's post at the top I'll keep looking but from what I gather I may have the sealed transmission with built in filter that cant be changed and maybe shouldn't touch it even to drain it. I see a lot of "if it ain't broke don't fix it" mentality about these transmissions on here but I'm a firm believer in simply draining and adding new fluid at times.

 

If your transmission is the same one as ours, the filter- pan, is made of plastic, and will eventually leak.

Replaced mine with a steel pan & the other type of filter.

 

Ok great at least I know there are steel replacement pans out there if need be. At this point just trying to find the standard procedure for draining the fluid and replace filter, but i have a good idea at this point

 

When changing Pan, filter, and fluid it is recommended to replace the electrical connector sleeve. They are cheap.
Also if draining and refilling 6 - 8 liters is normal. Compare volume of fluid drained out to fluid required to refill. If you drain more out than it takes to refill double check the procedure.

 

Again have you read Don's instructions for this?
He did a great job and it's all laid out in his thread.

Short version: He says don't use aftermarket pans.

 

Thanks for posting. Interesting video. There are plenty of high quality parts that are not OEM however. Some are even better in my own personal experience. Using one example in a video where a single pan had an issue is not useful.

If the guy in the video had actual data that sited multiple (I mean thousands) of examples demonstrating that a non OEM pan will cause problems, that would get my attention.

This transmission is used on Hyundai, Audi, BMW, Jaguar to name a few. Never heard of this problem. My last XJ SV8 now 16 years old. My current one 13 years old and has an aftermarket pan. It's doing just fine. I've read where a couple folks have complained about their pans cracking and not necessarily non OEM but have swapped out for metal. Hey you gotta be able to sleep at night so that's fine.

But there's always validity if you have something to support beyond a one off. A company's quality rating would also grab my attention. Example, suspension parts for our cars sold as kits on eBay by Deutsche Parts USA. OK reviews on eBay. Go to the BBB and they have a poor rating and you can read the complaints. Now you have something to ponder. Data. I suspect the ratings are done on eBay right after purchase or install and the ratings on BBB are a year later:-)

 

His video on rebuilding the ZF6HP26 is one I used to rebuild mine. He is pretty good in my opinion.

 

Interesting... I get my trans pan from Amazon. Used it about 3 times on different vehicles. No issues but definitely will be aware moving forward.

Matter of fact have to change my pan, sleeve on Sun as the original mechatronic seal (I presume) gave up the ghost and has a leak...

 

His video is one of several that I watched several times. You can pick up different pointers from different "experts" which can be very useful

He is the only one that spoke out about using the genuine OEM pan..

 

Gotcha. Speaking of rebuilds, how is yours going?

 

I am in the process of replacing my transmission cooler lines. One crimp started leaking pretty badly when I was doing the refill procedure.

Have the old ones out just have to put in the new ones. Garage is very cold right now!

 

What about topping up fluid? If the fluid is 124,000 miles old, you suggest just leave it until I need a new transmission?

 

Versions of these six speed ZF are used in many vehicles. Used to have three cars with one. A 335i and A8 along with XJR.
Even Lincoln Navigators used them. Saw a Lamborghini engine and tranny at salvage yard. The turbo V12 had a ZF six speed. They last if maintained. Heard of A8 going 400,000 miles.
Spend the 250.00 to get LG6, plastic pan, and sleeve. Will then outlast the rest of the car. I think a plastic pan is less likely to develop leaks than a metal one.
I changed the fluid, filter, and sleeve in each at either 60,000 miles or on purchase. Never touched again.
Fluid and filters always looked fine. But time and miles take their toll.

 

Greetings, fellow owners and enthusiasts. I have an '04 X350 with just 21k miles. Is the recommendation to change the transmission fluid or leave alone? There are no leaks and no noticeable transmission issues. However, I am wary that the car is 18 years old and the revised guidance from Jaguar was to change the transmission fluid after 8 years (I think). Does anyone have any experiences - good or bad - after changing transmission fluid based solely on age rather than mileage? Thanks in anticipation!
