Hi,
I have just dropped the car off for a service and a few other things done and I asked the mechanic whether any servicing/ change of oil filters etc is required for the auto gearbox.
Generaly it works fine but very occasionally snatches when pulling away on a hill, it also creeps a little more than i would expect and the engine revs drop a bit when holding it on the brake, but nothing that i would panic about.
But the car is 18 years (110,000 miles) and I dont have a full history, so as far as I know it might be the same oil that it had in when it came out the factory.
Anyway he came back and said he had looked it up and to do it would be about 250€ for the oil filters and any other associated parts.
He normally charges a fair price for his work, and is often happy for me to source parts etc, so pretty happy with him.
Anyway I told him to hold off for the moment and concentrate on the service and other problems and probably do it on a subsequent visit.
I just wondered if anyone had any experience or comments.
Dave

I’ve had several conversations about this on the 4.2 auto box having had 4 of them. AFAIR Toyota only recommend an ATF change if the car is used under “extreme conditions “, whatever that means. I don’t remember there being a service item for changing the ATF or any filters. Generally speaking there is a lot of debate about whether changing the ATF causes problems in that it can dislodge sediment in the oil ways which can then block actuators, valves or servos in the box. My Saab 9.3 required an ATF change every 4 years or 40K miles (AFAIR) and it was a bit of a nightmare. It had to be re-done 3 times before the box performed properly thus giving some credence to the “dislodged sediment “ theory. I never changed the ATF in any of the RAVs and they performed fine.

Further to the above, the symptoms you mention seem normal: the creep, revs dropping slightly when engaging drive. The hesitation uphill isn’t normal though. I don’t know whether it helps but I used to occasionally switch off the overdrive and boot the car in 3rd to sort of “clear the cobwebs”. No logic to it but I just felt that it gave the servos and valves that didn’t get much use a bit of exercise.

I’ve changed the auto box oil on my last and current RAV4, I didn’t follow any recommended time or mileage ,just seemed right to change it as I could 👍🏻
Last RAV4 I done at 84k and this one at 106k..only because that’s when I took ownership of them .

At the 6 year or 90,000 Kilometer service the dealer changed our auto trans fluid
and as that's what Toyota NZ recommend we had it done.

My 2002 auto box is much smoother after getting the ecu software 'flashed'. The car has done 104k miles and all seems fine now. Compared that to the 2006 auto box and altho the car had done short of 65,000 miles, I felt the take off was a bit snatchy, and wondered if the ecu also needed flashed. The forii differed in views as did the ecu testing companies with one saying the ecu 2001-2003 needed flashed; whilst another said 2001-2006. I considered changing the auto box oil, but in the end other issues led me to sell the 2006.
I am considering getting the diff oil and transfer box oil checked and changed if needed. The handbook says no need to change the auto box oil unless one has been towing ..this hasn't.
The Volvo XC90 2014 car I had needed the oil changed around 108,000 altho there was debate about that too. I got the oil changed at 75,000 and again at 110,000 as I felt the gear change was becoming a bit jerky. Changing the oil was basically emptying what would come out; filling it; running it; then repeating this at least 3 times until the box oil was coming out clean. An expensive job as the oil itself was £120.

Changing the oil was basically emptying what would come out; filling it; running it; then repeating this at least 3 times until the box oil was coming out clean. An expensive job as the oil itself was £120. That was my experience with the Saab, Ian. Even though it was an ex-Saab main dealer specialist they had to change the ATF three times before it behaved properly. Fortunately I only had to pay once as they felt that it should have been okay the first time - because Saab had said so….. They felt in the end that it was dislodged sediment that was the problem but the fluid had to be changed every 4 years per Saab’s service schedule. The box was an Aisin 6-speed with flappy paddles to effect manual changes and it was a superb gearbox, just a shame that the ATF changes weren’t straightforward. |

Interesting. Don’t flush! Sediment (incl’g clutch particles) is your friend. 😧 |
