Thread: Automatic oil refill question ..

I am 2 litres short, what are the tips as I never did this on discovery? I am assuming that tranny needs to suck up more oil and I am only guessing do I take off the filler plug, let the car run like that and just keep feeling as it needs more? Thankyou all

Was the car idling as you checked the level?

Hey mate, no I filled it up when the car was off then I started it and shifted all the gears.

Sorry for my ignorance but what I can see on the internet is once the first 2.5 / 3 litres are added cold , you must start it let it warm up and while someone is shifting the gears top it up while the car is running... is that correct?

It does make sense, auto sucks in more oil inside the gearbox from the bottom sump when it's running.

After what you've already done, just top it up with the engine idling... Should be good.

When I 1st saw this thread I thought, "Oh no a fuel injector is leaking fuel into the sump!"

Before I can start the car for longer and do this, I need to fit back the cooling system.. almost there.

I've also saw on the forums that car should be idling in N while you are filling up the rest of the fluid in the box, apparently this way it will take in those additional 2 liters that I am missing.

Does this sound right?

Thank you.

At the risk of quoting myself, check post 4.

Thanks champ!

do it while the engine and trans is cold while the engine is idling.

the correct level is when a bead of oil about 3mm in diameter is running out...


once thats done, degrease the oil cooler lines and then wipe them dry paying particular attention to the connectors from the hoses to the pipes for the cooler side connection....

take it on some very close to home short circuit runs untill the engine and trans have warmed up.

Do a very abbreviated stall test and then check the connections for any signs of oil.
