Hi every Lexus lovers 🙂
I want to say very big greetings for everyone who take their own time and experience to maintain our Lexus and share their experience on our forum.
Today I spent all day to find a possible way how to fill in a transmission fluid to GS 450h e-CVT transmission. My Lexus reach 110 000 miles and I thought that will be a kind of obvious of maintanance.
It seems like it is not possible. Many of YouTubers, a lot of of forum's says that you wiil need a few tools and some experience. OK... that's all true, but not for my Lexus. My "gearbox" is a e-CVT transmission, which looks like a Lexus improved model, really do not need a transmission fluid change or refill. I attache a photo, maybe not very good quality, but real photo from the face-lift model.
Everything looks good, we have got drain plug, we have got a level plug... but where is a filling plug? Just not exist. Only one possible place, marked on the photo. Can anyone confirm? Very difficult acces... not surprissingly wrong according to no-maintanance gearbox, on the top looks like for allen key ( again ... can anyone confirm a size of tha allen key? looks like 6). Honestly I think to make a serious service with the transmission, I'm going to remove the oil pan, change the gasket and filter, fill in a new fluid. But WHERE IS THE FILLING PLUG?
Another question is... what type of fluid works in the e-CVT transmission? According to any information found on the websites it is a ATF WS... but none of those websites is for 450h, hybrid version.
So... I'm confused still, I have a lot of electro-mechanical skills and experience in maintanance, but Lexus never going to stop surprising me 🙂
