I would personally leave the gear box well alone. Even an oil change, can not be done in one go. They have to be topped up driven, then topped up again.

As @ColinBarber said it's the Aisin A960E. It's written on the side stick when you open your door. The same stick that has your paint code.

I think there will be lots of opinions on this. Ive worked with a good few A960E transmissions. Just recently I teared down a 2012 A960E with 70k miles on original oil. It was absolutely filthy and metal particles were of concern. I've worked on a few with that kind of mileage and all have shown similar signs of wear. But I guess it's upto every owner what risk they want to take. I've got nearly 200k on mine while regularly servicing it and happy with that. My first service I did neglect and that's where most of my wear and tear occured.

There is indeed a lot of opinions and advice as you say.

Lexus say its a " sealed for life transmission" 

Having worked for Getrag transmissions for 34 year (manual only) I have seen the state of the oil after about 60k YUK ! 

The box is made by AISIN I believe and they recommend the filter and oil changed at 40k .

Getrag called there transit box a sealed for life , but what does "life" mean?

Is it the entire life of the box ? or the life of your warranty ? 

Expensive job , £83 for the filter , oil about £60 ish plus labour . 

But how much is a replacement box ?

Got me scratching my head whether to have it done or not ??

ATF has an easier life that manual transmission oil but still degrades and internal filters don't entirely keep it clean.

If you operate a vehicle under a severe service schedule (towing/high load or prolonged very high speeds) then the fluid should be changed every 6 years/60k miles according to the official Toyota/Lexus service schedule.

I think it is worth changing even for vehicles not running on the severe schedule. The main problem is just dropping the pan and replacing that fluid only changes 1 litre - less than 1/7 of the total amount.

If you measure the amount of fluid you remove and put back in the same amount you don't have to go through the fill/level procedure 🙂

I've heard that a lot of dealers in the states are now all suggesting customers have transmission service at 60k which makes a lot of sense. I recently cut open a filter from a 70k on original oil filter and the filter was no longer able to efficiently filter the oil. Every oil breaks down, no such thing as oil that never breaks down.

I change my filter every 60k. If dropping the pan and draining and re-filling then I think the temperature dependant fill/level procedure is essential. But in between I do a trickle change just like @ColinBarber suggested where I drain and measure how much came out. Then re-fill the same amount. Then I drive around a bit and repeat a few times just to dilute old oil with new oil. The WS 1L bottles really arn't that expensive so well worth doing in my opinion. Better to dilute it a little than have completely nasty oil inside.

Had a ring around today to see what I could learn about these transmissions (A960E) 

Tried to speak to Aisin directly but it proved impossible , but did get to speak to a firm of automatic transmission specialists in Cornwall of all places .

JPAT Automatic Transmissions Ltd.

They deal a lot with AISIN , they told me according to Aisin, the A960E should have an oil change at 40k AND a filter.

Spoke the the guy for some time on the phone , very knowledgeable !!

Anyway they strongly recommend an oil and filter change .

Lexus oil filter is £85 .... they fit, and have never had a problem with an American after market filter at £17.50 bit of a difference !

The gasket is £3.60.

So am I to understand that , with the drain plug out I will only be able to get about 1ltr of oil out of this box? Is that the same with the pan off ??

Guy on youtube reckons he dropped nearly 6ltrs from his??

40-60k is a very reasonable time. Like i said in between a little trickle change will also help keep things in tip top condition. Best to use a garage that has worked on Aisin gearboxes too. I've used aftermarket filters with gaskets and haven't had any trouble. They are a fraction of the cost. Remember there are O rings for the filter inside, then their is the main sump pan gasket as well as the drain plug washer.

I don't think you get out 6L at all. There is a lot of oil inside the torque converter and the housing itself. The entire transmission itself only takes around 9-10L, so it makes no sense that you can drain 6L out of the sump. If i remember correclty, if you are lucky you can probably drain about 3L or just over that.

 

All the best.

Closer to 5 litres rather than 6 as he put in 6 quarts and nearly all of the last quart overflowed. But that is for an AA80E transmission which is larger and hold more fluid than the A960E.
