I just want to add few things I observed after doing both front and rear fluid changed. I had my RX400h on the drive way so it is a litle up hill.
For front CVT, I saw Lexus put more fluid in the gear box because alot of fluid came out when I opened the fill plug. I measured the oil and it is 4.4 qts total but I was only able to put 3.6 qts back in there. It is bug me that now I have .8 qts short so I tighten the fill plug and and drive the vehicle with both passenger wheels on the ramps. I was able to add another .8 qt.
. Both fill and drain plugs are the same with out magnet.
For the rear, it is alot easier to change the fluid because the amount drained out and filled in is very much the same. It is about 1.8 qts. The drain and fill plugs are not the same. The drain plug has magnet so you can see some fine metal attached to it.
Oh, it is 2007 RX400h AWD with 90000 miles.
