It is perfectly straightforward to drain correctly, add four litres, drive to warm the box up if you wish, and then check the level following the correct procedure.

And just to add, that IMO, it is more important to check that the car is completely level than to measure the exact temperature of the fluid, as I feel this would have more of a bearing on the correct transmission fluid level.

Here's an anecdote for you at the factory.
brand new car pushed off the the production line no drive.
around to us to have a look go through procedure for Jatco check all values at solenoids all ok, check gearbox oil all ok,
phone Jatco rep, he comes in says add a litre of oil, done, no drive.
change the drive shafts, done, no drive.
gearbox changed all ok car passed to sales.
a week later word comes back from QSYS (damaged parts for warranty) the gearbox in question contained no drive plates.

My car had done 60k trouble free miles with smooth gearbox changes.

MGR filled it last in the factory!!

I added exactly what came out and put the same back in. All ok and still have smooth changes now on 70k.

That is because you knew when it was last filled up! Unless bought from new most owners haven't got the faintest idea what has been done to their cars.

Thanks for this Terry. A story like that makes us all feel better!

Just noticed the bottom line of your post Simon.

Spitfire ace Geoffrey Welham drives a Rover 75. Enough said.

Glad to see from your by-line that WW2 veterans don't have any hang-ups about buying things from our old enemies. Hope he has an auto with an M47R engine.

The 75 engine (if it's diesel) was built in the same factory in Steyr Austria that the Lancaster boys visited in 1944 / 45.

The Jatco auto box comes from the Land of the Rising Sun.

My Dad - ex Normandy and Arnhem now drives a Mercedes Benz.

He was saying some of his pals down the British Legion are still reluctant to support non-British things.

Glad that's all history now.

Thanks for that Bob. You're the first person to have commented!

I must admit I hadn't considered the valid point you make. I just like the idea that someone like Geoffrey is clearly not one of the mythical 'pipe, slippers, tartan rug and travel sweets' brigade! Did you see Matthew Whiteman's excellent television drama-documentary about him?

Simon.

Footnote: Yes, it's all history, but I feel that it's a lesson of which every generation should be aware.

Really? You've got nearly 2000 posts and I'm the first to comment!

Yes I've seen the film. More than once. It's even been on the History Channel here in Bosnia.

'Those who don't learn from history are doomed to make the same mistakes again' or something like that - if I remember correctly.

Maybe I notice these kind of things more than most.

I'm back here in Bosnia right now doing what little I can to help with both the mine-clearing - only another 80 years to go at the present rate of clearing - and the swapping around of artificial limbs for the kids. It's very sad to see schoolchildren with the wrong size of leg - they outgrow them so quickly and there are only so many to be passed down.

They are still losing feet, fingers, legs or worse in the rural areas when they are foraging for wild mushrooms, berries etc.

If find it a very rewarding job as these are some of the nicest, happiest people I've ever met. After the war I just had to keep coming back.

Best regards, Singvogel.

Don't forget that you can never completely drain an auto box in situ due to the oil in the torque converter.

Safer to put in the same quantity that came out.

Safer than what?
The safest is to do what should be done, fill until the overflow flows.
You never know the history of the car. I might have lost oil during a repair or leaked oil, the only guarantee you get by replacing what is drained, is that you are back to where you were, with about half the oil replaced. You don't know if it is right.
