2010 RX450h Transmission Question
If anyone has a factory manual for a 2010 & up RX450h, I need to know how to check the transmission fluid and how to add the proper amount. No dipstick in sight and I've looked at a bunch of threads here with the "don't worry about it, it's lifetime..."
My issue is that I bought a front end damaged RX that had the cooler killed on that corner and the lines were cut. Got all new stuff back so I need to get back to the proper level in the transmission.
If you can help me out, I would really appreciate it.
Thanks in advance
John

I wonder what the code is to accomplish this:
(c) Set the vehicle to FWD inspection mode. Click here for more information.

Strange statement. I have changed the fluid four times on my RX400h. No problems so far and I am at 145k miles.....

Just came across this old thread.
That would be this: https://www.clublexus.com/forums/hyb...ance-mode.html
I suspect this step is just to warm up the old fluid to make it easier to drain more fully, as the volume of the warmed up ATF will be greater than when cold. Personally I think this step would be entirely optional.
Part number can vary depending on market.
For North America, the fluid is made in USA and the part number is as per the back of the 1 quart plastic bottle:
The fluid is also made in Japan and this is the part number:

It is not a CVT. It has nothing in common with a CVT or a normal multi speed automatic transmission. It really has only one gear and it works with the electric hybrid system into which it is integrated.
It is, in Toyota official language,a Power Transfer Unit. It is very simple in design. It is extremely durable. Just change the fluid every 50,000 miles or so and it should last almost forever. Changing the fluid in it is very simple. It holds 4 quarts of Toyota WS as identified above. Fill it up until it flows out of the fill hole and you are done.

It is all gears and not belt based. A beautiful piece of engineering that allows multiple power sources to combine to drive the output. No slush-box as in automatic transmissions.

so sounds like predecessor of the current gen THS eCVT (the planetary gears) ?

"The eCVT found on the Toyota Prius and other hybrids differs from CVTs found in other vehicles, such as the 2013 Nissan Altima or 2012 Scion iQ, because it does not use a belt or chain connected to a pair of variable pulleys. Instead, an eCVT uses electric motor/ generators to control the speeds of planetary gearset components. This allows the eCVT to continuously change the gear ratio, keeping the engine’s rpm in the sweet spot. Just like when driving other CVT-equipped vehicles, drivers of vehicles with eCVTs don’t feel the step change common to traditional automatic transmissions, yet the mechanisms (planetary gears) to achieve acceleration are largely the same."
