I use different method to flush the ATF 3.2 What you think?

Hey guys,

I have a 2008 Volvo XC90 with 3.2 Engine same as the one in the LR2

Last week I flush my Transmission and use a different method.

I hook the transparent hose to the radiator and use the same return pipe/hose to poured the new ATF fluid. Please check the photo to understand better what I done.

I remove 2 quarts and then filled 2 new quarts until I complete 12 Quarts

This way I don't removed the air filter housing.

What you think about this method?

Here you can see I use the same ATF factory return pipe/hose to filled the new fluid

Old ATF Fluid was dark


I use Wolf Lube ATF Brand Manufactured in Belgium


Here you can see is Aisin Wagner 3309 and Toyota Type IV Compatible

Whatever method you use, if it works for you its all good. The main thing is that the fluid has been changed. Thumbs Up Past: FL2 TD4 HSE Auto

Are you just using gravity to feed in the new oil and does this force the old oil out? Landrover - turning owners into mechanics since 1948

Probably he is starting the engine for short periods of time, for the autobox pump to circulate the oil.

Hi

Can anyone advise the internal pipe diameters needed for the return pipe and cooler in this type of transmission flush as I want to do mine later this year.

I start the engine in order that the transmission pump out the ATF Fluid. When the transmission pump out 2 quarts, I turn off the engine, then I filed 2 new ATF Fluid.

The only different thing I do was to use the return pipe that I disconnect from the radiator to feed new fluid.

The instruction call for removing the Air Filter housing and remove a large screw in the top of the transmission to feed there the new fluid. I just avoid this method and use the return pipe that I disconnect from the radiator.

Check the red circle. That factory pipe/hose is the one connected to the radiator. I connect there a clear hose to filed the new fluid



We use a hose with a funnel to filed the new fluid.

Thanks for that.
Are you refilling the exact same amount you take out or do you check the finish level with the drain plug removed?
Do you think this method changes most of the old oil from the gearbox, is it pumping out clean new oil when you finish? Landrover - turning owners into mechanics since 1948

Yes, I remove 2 quarts at a time..... Then filed 2 new quarts. I do this until I filed a total of 11.5 Quarts.

Then I filet the remaining ATF Fluid in order to make sure I was above the drain level.

Then I hook up the return pipe to the radiator using new O Rings and new green clip.

Start the engine and cycle from P to R and D several times............. Put the transmission on P

With the engine still running, remove the torx 40 screw from the drain plug and fluid come out until stop.

Leave the screw out in order that some fluid dreep and wait until the temperature get to 60º C ...... I use a Digital Laser Thermometer to check the temperature.......... It took a while until the temperature get to 60º C and then I put the screw.

The fluid that was dripping was clean red.

I am pretty sure this method changed most of the old fluid on the transmission.

The good thing about this method is that you don't need to remove the air filter housing, neither disconnecting the MAF sensor, etc, etc

Also as the returning pipe is thinner, it takes a little more time to enter the new fluid. So take your time by adding the new fluid little by little to the funnel to let the fluid in.
