This was the gearbox in my Disco 3

102k miles, previous owner had never had an oil change

Oil capacity is 11 litres

I drained the box, replaced the filter and torque converter, which took 6.5 litres to refill

The gearbox input seal then had a leak, so the gearbox was drained, TC removed, new seal fitted, then a further 5 litres to refill

Then the box was flushed. Old oil on the right, new oil on the left...
I'll let you decide how much of the old oil was still left

All the ATF Ive seen is red .

Re read the first line

D3s not have ATF in their autoboxes then ? Jules

Not all ATF is red

No need for I thought that as my manual Disco had red ATF in it then maybe some autoboxes didnt use ATF.
I didnt know that no all ATF is red - everyday is a school day.

Can I ask why it is often coloured red. Jules

You said: ...my manual Disco had red ATF in it...
Sorry for asking, but if by manual Disco you meant that it is equipped with a manual gearbox, then how can a manual gearbox have automatic transmission fluid (ATF) in it???

As per your last question, the color of ATF is the result of a dye that is added to help you distinguish it from other fluids in your car such as engine oil, power steering fluid, brake fluid, and antifreeze.
Note1: While not as common, transmission fluid can also be other colors such as blue and yellow.
Note2: Certain windshield wiper and antifreeze fluids can be red, so make sure you always read the label first!

Sounds weird I know but its true (I did my own servicing and had to double check). The manual LT77 gearbox had ATF in it as recommended by JLR.

And if I remember corrrectly the R380 manual gearbox in Discovery and Defender used 10w40 engine oil?

Just searching for suitable autobox oil at reasonable price and came across this:

Seems to be the correct spec and very cheap. What do you all think? Landrover - turning owners into mechanics since 1948

Thanks for the info. Like you've said, everyday is a school day.

Until MTF94 was developed, that then became the go to MTF for all manual cars, until FL2/D3

MTF94, yes thanks for that Mikey. I had LT77 and R380 equipped Discos in the past, ATF was an alternative fluid. I was incredulous when I saw it. But then I learned more about the LT77 and the cynical disregard of JRA for it's suffering customers.

Yet I still buy LR products.

Well I changed my autobox oil today.
At 65k miles it was about time.



I used 10 litres of Mannol ATF (of the correct spec) got it on ebay for £32.99 delivered, including a 20% discount code.




Decided to drain the box then re fill the same amount, 3.7 litres initially.

I then removed the bottom pipe coming from the oil cooler (I CAN CONFIRM THAT IT IS INDEED THE BOTTOM PIPE YOU NEED TO REMOVE) and drained around 3 litres on 2 occasions with my son operating the engine. By the end of the second purge fairly red fresh oil was coming out.



All well and good up to that point!

Reconnected the pipe and tightened it up. Started the car and let it idle in each gear posotion for a few seconds. Before taking it for a drive I looked underneath only to see ATF running out of the pipe connection! Took it apart again to discover that the o ring had split. Oh Naturally Id not bought one for the job. Went to my local motor factor and got 2 similar sized O rings. Unfortunately neither of these were correct size and it was still leaking

At this stage I had a bit of luck, I went hoking through my tool cabinet and located some genuine LR O rings which Id had since changing injector seals on my Td5 Disco, a perfect fit!



All sorted and level checked. A fairly easy job which was nearly derailed due to a little rubber O ring!

Fortunately my cat is an auto gearbox expert and was on hand to offer advice!

Nice write up Bob, glad it all went well, looking at doing mine some time this year, and I will be looking to flush it through like you have, will make sure I have a new "O" ring thanks for the tip.

I have been looking at which ATF to use and it appears to be a bit of a mine field, can I ask why you used that particular auto transmission fluid not that particular brand but the specification, if I am reading the label on your photo correctly it is JWS 3309 specification, It was my understanding, and I stand to be corrected on this, that after 2011 the specification was changed to a AW-1 with JWS 3324 rating, perhaps someone who has with more indepth LR knowledge would be kind enough to confirm the correct ATF for a 2014 model as I want to make sure I use the correct type.
