Auto tranny fluid change
#1
#2
If the total mileage of the car is only 18.5k then I would leave it alone if it is running well unless it has been submerged under water or something similar. If you did decide to change the fluid you might as well do the full pan/filter/sleeve etc. but it will be a waste of time as the fluid will be like new. Although Jaguar's "sealed for life" recommendation is nonsense, the ZF gearboxes are definitely "sealed for more than 18.5k".

Guess I am searching for time based changes to the fluid in the auto tranny or something like it.
Thanks Richard! for you've strengthened my belief that the tranny fluid should be fine on account of the low milage.

I dunno about that Richard - I found this on tinternet:

Dear Distributor:
It has come to our attention there is confusion in the field regarding service intervals and fluid recommendations for ZF 5HP and 6HP applications.
ZF has promoted lifetime service for many 5HP and 6HP factory filled transmissions. Lifetime is not clearly defined and each OEM manufacture has there own philosophy. ZF stands behind lifetime recommendation where listed in the vehicle operator’s manual. ZF engineered and tested our fluids to retain its characteristics through normal lifetime operating conditions. However, a spirited driving style, special environmental considerations and other individual driving factors may place higher than normal loads on transmission fluids. To assure proper operation it is advisable to perform a drain and fill at 100,000km/62,000 miles or eight years.

My two cents, worth maybe half that, attached is the letter that @McJag222 references. That said, the OP is @ 18.5k kilometers on a 9 year old car. The biggest risk to the transmission (or the engine for that matter) would be gasket seal leaks from non usage imo.
If you want to follow the manufacturer's recommendation, do the drain and fill.

Will go ahead with the drain and fill
Sorry to the mods for back to back posts , will try to multi quote next time , am a newbie

You dont have to replace the filter that often. Have you ever seen a dirty zf6 transmission filter? Ive owned the car for about 5 years and Ive replaced the pan/filter once and then just the fluid once every two years to ensure that it remains as fresh as it can be. I do drive a lot so its how I do it. Im sure that I will again replace the pan/filter/mechatronic sleeve but only if the pan starts to leak. It’s not as expensive to maintain a ZF6 if you simply swap out as much fluid you can get out without having to tear it all apart.

If it was my car and plan to keep it for a long time I would change the transmission fluid and filter for piece of mind. Like others has said, its a semi-synthetic transmission fluid and ZF recommends to change it based on age and mileage. If you're worried you can stick with the OE ZF fluids. I personally used Amsoil 100% Synthetic transmission fluid to keep oxidation levels and temperatures low without thermal runaway when driving spiritedly.
Its not hard to do the drain and fill of the transmission fluid and you can either DIY or go to a transmission shop. The auto 6 speed is a fairly common transmission use by BMW, Ford etc.
