Changing 2015 Prius Transmission Fluid

Ah sorry, missed that. Yeah do this only on level ground.

 

I knew this would come up.
So don't use a brand name high quality synthetic ATF. Use the dealer's generic ATF that is used fleet wide. Why?

 

I’ll bite: Owner’s Manual warning, regarding damage with anything other than Toyota ATF WS?

 

Because of taxes you won't get $60 for the hour you'll get 45. And because the oil change place has hidden fees like waste disposal fees Florida surcharge fee it's a Tuesday morning fee and oh by the way I'm selling you an air filter you don't need fee and they let dirt bypass and now your mass air flow sensor throws a code and the few hours that you waste sitting there to watch them strip all your bolts and put in a cheap no name fluid which will cause problems later anyway we'll wind up costing you $95 plus a whole transmission plus a mess air flow sensor plus 3 hours of your time dicking around. I would do it myself Thank you very much. It would take a nurse 2 hours of overtime to pay the BS bill at the jiffy lube to get an inferior quality job done. Plus the nurse would have to sit there for a few hours and his time is worth money as well so his net loss will be far greater by taking his car to the goons with some generic lube where they strip all his hardware. My IQ is a lot higher than the collective at the teenager's first site (lube shop) of employment down the block.

 

Either way I'm sure a shift of overtime will make enough, typically 12 hours. Buy the 4 quarts of WS and get it done!

 

But if it's a DIY, why not buy a high quality synthetic ATF for a little bit more?

This is my choice. It's not the OEM product and I don't assert it's equivalent. But I have used in a dozen Prius so far and never a problem. You decide what u want. If u get WS at the dealer it's guaranteed perfect every time. Up to you

 

I just use ramps. I measure what I drained out and put the same back in

 

What happens if there’s a leak and you only drain out 1 quart? How mucj do you fill it back up?

 

You're underfilling. Probably ok but thought u should know

 

Yes, if car is tilted by front-only raised, the fill hole, being towards the rear, will be overflowing sooner. How much less you can get in is directly proportional to the degree of tilt.

Might still be within spec (attached). I could do a rough estimate of the volume less (with cad), at a few angles.

 

Or have the rear on its wheels up on a hill.

 

Door sill and your phone's 'angle/dangle' app is how you get level!

 

Ahh, crawling under a car jacked up on a hill is maybe not healthy. You don’t want to improvise with stuff like this.

A level concrete slab, ramps, safety stands, wheel chocks and a decent floor jack. And even then, I like to push a thick/squat section of tree trunk under there, just in case.

 

No, I meant on ramps, not "jacked up."

 

Regardless, getting under a car on a slope is getting into Darwin Award territory; it is not hard to get a car raised and level (on level ground), either with ramps on the front and safety stands aft, or safety stands all ‘round (my pref).
