New XM owner possibly

[aston]

Hi all, I needed a diesel car for my daily commute so put in a bid on an SM on ebay, Well it looks like I won it, Hope it's OK as it needs to do 500 miles a week.
We shall see how it goes, It's a 2.1 td Auto with 172k on the clock (Full MOT) Just waiting for the owner to confirm the car is sound before I move on it.

Hi Aston

Welcome to the club. The 2.1 is the best engine, don't know about the auto box though There are not may manuals about now sadly. They are certainly a nice car, nothing beats them for comfort. Enjoy.

Hello Aston

Congratulation with acquiring one of the second most economic Xm versions.
It is beaten in mileages per galloon and maintenance by the manual gearbox version.

Take care of the ZF 4HP18 autobox!
_ _
The 4HP18 autogearbox has to have clear red DEXTRON III / or the original by ZF prescribed Dextron II.
But take care when changing oil, somewhat 3,2 litres (my measurement) out of 8 litres when a change is made. The oil level has to end up in middle of the “warm indication” for normal driving. This leaves a proper expansion area for city driving on a hot summer day. But anyway selct N (neutral) with idling in a traffic jam.

Receipt for a service on the 4HP18 autobox:

Warm engine and gearbox /after at least 10 miles of driving.
Let the oil out (the side of the box near to the bottom hexagon 8 mm)
Remove filter (bottom lid with three 8 mm bolts)
>> Beware of warm oil / use old garden glove
Remove filter
>> Beware of more warm oil
Clean filter and the magnet in lid (6 grammes of deposit cab be held there)
Reuse filter if net is ok
Refill - through the dipstick - with the same amount as emptied out.
Check oil level / warm marking is accurate.

NOTE: If DEXTRON III is new to the gearbox you have to be keen on changing with short intervals because it has more cleaning power han Dextron II, and loosened residue can be dangerous.
Never the less if the colour of the gearbox oil is far from clear red, oil changes has to be made with short intervals.
If color is red and the smell is like new oil then change regularly at 16.000 miles.


If the oil is burnt the gearbox is in danger, complete change of oil can be made by flushing.
Empty out – through the cooler connection _ and fill through the return hose to the gearbox.
This takes 10 litres or more and the adjustment of the level will be time consuming.

The mechanical adjustment can only be made on tolerances on kick down cable and brake bands, but if the box is working properly then leave this out.


Good luck with the XM autobox and the luxurios car.

Best regards
