Was reading about a fluid change on a 6 speed . the writer on this forum drained the old fluid. tipped the car up to get the filler on the high side and put in 7.5 litres of new fluid. Job done.
Does anyone have an accurate re fill figure for the 5 speed as I dont have a tall level lift for easy access but can use my brake bleeder to pump in the fluid easily?

 

The five speed ZF gearbox that you have, is different to the 6 speed ZF gearbox.

The five speed gearbox that you have is a Mercedes Benz 5G-Tronic(722.6 transmission)
The 722.6 is the transmission a series……… and the W5A 580 is the Jaguar sub series.

Jaguar’s W5A580 reference means……wide ratio W, 5 speed 5, automatic A, 580nm torque capacity.
This is the strongest transmission of the MB series, used only for v8 and v12 engines. high torque capacity, up to an actual 1000 Nm.

The oil should be Shell ATF 3403-M115 or at Mercedes Dealership the oil reference is A 001 989 21 03 10
The MB specification number is: ATF 236.14 (google this spec and it will give a list of equivalences).
9.5 liters are required.

The Mercedes 722.6 pan gasket service kit is recommended over the Jaguar.
The electric TCM plug that tends to leak the part number is: Mercedes pn 203-540-02-53
The Mercedes Automatic transmission flexible dipstick can be bought on Amazon or through Mercedes.
The dipstick ATF red clip part number is, Mercedes A140 99 100 55
All of these items are remarkably cheap.

The five speed Gearbox has a dipstick. The dipstick is really long for trans tube, you have to remove the fill plug on the right side of the engine compartment.
The dipstick cover requires a small screwdriver to depress the locking system from the top, The retaining clip will snap loose under the dipstick cover, catch it, don’t loose it! There is a picture bellow of what the dipstick looks like.

Fill oil to lower cold level on the dipstick at 25 degrees C
The temperature is critical for any measurements and that it is done with the car on the level, in neutral and the engine idling.
COLD LEVEL 10mm to 20mm is 25 degrees C.
HOT LEVEL 55mm to 65mm is 80 degrees C.
The simplest way of checking the temperatures of the gearbox is to use an IR scanner.

If you over fill the gearbox it aerates the fluid and the hydraulics functions fail.
In an auto gearbox it equates into low fluid pressures and it smokes clutches!!

I did my servicing using axle stands

I hope this answers your questions.
Very best of luck and have fun.

 

The 5 speed does not have a dipstick so thanks for all the effort in typing it but I must wait for other advice.

 

according to to OP's profile he owns XK8 not XKR so transmission is 5 speed ZF not MB.

 

I guess you could measure the amount that drains out and refill with the same via one of the trans oil cooler lines - assuming that the level is correct in the first place.
You'll get about 4½ litres out, the rest remaining in the torque converter. Most do an additional drain & fill after a few miles to further dilute the old fluid.

Best if you can get on a lift or jack stands (if you're comfortable doing so). That way you could address the filter and perhaps the main PR valve?

 

thanks for that .I have got ramps with hydraulic lift platforms at the top so up is not a problem but getting up and level is . No service record of it being changed but must wait for warmer weather to check.

 

My apologies. I didn't read in your profile you have an XK8. I stand corrected.

 

No problem mate

 

This is how ZF says to do it.

Good luck.

 

It is critical to have the vehicle level...thats the problem with ramps, First thing is to check the colour of whats in there.......

 

this isn’t that difficult

 

With the rear wheel 1ft in the air it wont be level so I could fill it ( thats overfill) drive it down the ramps ,do the gear bit and then jack the 4 corners onto bricks to get the filler out ( with difficulty),
All depends on the colour of whats in there .

 

Can you measure what oil comes out - say 4.5 litres and then just put back 4.5 litres or am I being simple minded? I suppose it depends a bit on the oil temperatures.

Also I assume to check the colour of the current oil you need to poke something in through the filler hole and get a sample?

 

thats assuming you weren’t under / over filled to begin with. Better to get A/T up to temperature and check level .

I know the 4.0 XKR transmission uses a dipstick for cking level, don’t know if the 4.0 XK8’s use a similar method.

I carried out a fluid, filter and conductor plate change on my 2000 xkr some time ago after a couple of years ownership and simply replaced the volume of fluid taken out.
Prior to work l could not get dipstick reading but had no issues with transmission operation.
It turned out that dipstick tube cap O ring had been displaced and was blocking dipstick access. Subsequent dipstick reading indicated 1 litre overfill which was removed.
Gearbox operation was faultless at both fluid levels, so it would appear fears of consequences of overfilling are somewhat exaggerated.

 

ordered up a filter and gasket for $15 and 6 qtz of the correct 71141 fluid for $27 all inc delivery ..we will see when the weather gets better

 

PB,
I'd recommend to use the ZF OEM filter. I've read a few instances of problems with aftermarket. See this thread from Katlover:

Filter at 11 min in ...nice oil colour ! Interesting he says blocked filter causing noise which is what I am chasing .....Many thanks as always for your impeccable input to the forum.

yes made in germany

 

Doh! I posted the youtube link instead of the thread

Looks like you got the parts in a kit:- if not, don't forget the 'O' ring as it has a separate part # (LandRover p/n TYX 000100). Good luck with the pan bolts - I gave them a squirt or two of penetrating oil a couple of days beforehand,

Why ZF chose the odd size of T27 is anybody's guess - particularly since that turned out to be a faux pas and the replacements are now T40.
