On my RAV4 non hybrid, there is also a front transfer case service. Trans takes ATF fluid. The transfer case and rear diff take gear fluid on mine. I tried to get my local repair place to do the transfer case and rear diff for me, but they had a lot of questions, didn't want to do it, and didn't have the correct fluids on hand. Didn't give me much confidence. It's just regular gear fluid. I got inspired and did it myself. 60k seems about the right time to do it.
I have a 2019 Camry Hybrid w/ nearly the same drivetrain, minus the rear diff. I serviced my transmission for the first time at 105k miles. The fluid coming out looked practically new. It was a little dark, but still very much red like Toyota ATF-WS fluid. 60k is a good interval, probably a little early IMO, but it would not hurt.
Does the rear use ATF WS?
Do you guys do the specified fill procedure - or just measure what came out and refill.
Not on my nonhybrid. Regular gear oil. The stinky kind.
Rear diff should be Gear Oil. Don’t quote me on the grade though I think it’s the LX or LT 75W90 GL-5. The OE bottle of fluid is very expensive so may want to seek aftermarket options.
Everyone I work with including me uses the drain and fill method just measure what comes out and put that much back in for the transmission/transaxle. For the differential we do drain and fill back up till it starts leaking out the fill plug.
Cool, thanks for your response!
We recommend doing it then. We leave it up to the customer if they want it then or wait. Most of them go for it at that point since it’s what Toyota recommends and we are already doing the other stuff at that point too.
I thought Toyota says 100k/10 yrs for the inverter coolant and engine coolant systems. Then 50k/5 yrs there after.
I mis-worded that my bad. Yes 100K. I meant they the customer usually want it done while we have it in the air doing the other services I see a lot of them being sold at 60K.
Unless I am mistaken, this model RAV4 hybrid is simply fill until it dribbles out the fill hole. There is the trans and rear, and both use WS.
The rear doesn’t use ATF its gear oil in all models for the rear.
Even the hybrid? Thanks!
Yeah including hybrid. No problem let me know if you need anything else.
Wow. I’ve never came across one with ATF in the rear not on these Toyota at least. I’ll pull up the factory service manual tomorrow and see what it says because I’m curious now. Every hybrid one I’ve worked on has been ATF up front and gear oil in the back. I know it’s gear oil by the color and smell. This is interesting but a quick google search I could not find a straight answer for the hybrid model either so I’m truly curious as to what my manual says on it.
