What are the tools and TIS procedure for changing and adding fluid to the transmission on the 2013.
Post #11 in this thread is an overview of what alternative specialty tools I used. Other than those, you just need hand tools.What are the tools and TIS procedure for changing and adding fluid to the transmission on the 2013.
Makes sense to me. Thanks for the post. Personally, I'm happy with the sealed tranny, as it's one less maintenance item for me to worry about. I changed the manual transmission fluid a few times in my 2003 Matrix and while a relatively easy job I can see how one could easily put the wrong fluid in, by mistake. It's even easier to do in an automatic transmission with a fill/dipstick tube. The shadetree mechanics on the forum may not like it, and some have even inspected and changed the ATF in 2013 Ravs. If people feel comfortable doing this that's great, but I won't be. I'll leave that up to the pros.So here are my $0.02 on sealed transmission.
The main reason why many manufacturers are switching to "sealed" transmissions is to prevent owners from mixing OEM transmission fluid with a wrong aftermarket fluid. Transmission fluids have become more specialized over time and consequently less compatible with each other. A fluid for a modern CVT transmission has very different properties from a fluid intended for a planetary gear transmission. Mixing incompatible transmission fluids can result in damage and expensive repairs. Considering that most manufacturers give now 5 years / 60k miles drivetrain warranty, it exposes manufacturers to the risk of expensive repairs due to user damage that is hard and expensive to fight.
90% of car owners never read the user manual, have no or little clue about how to correctly measure transmission fluid level and don't understand the differences between fluid specs and intended use. Just look at this forum. Most of the questions posted here can be easily answered by quickly checking in the user manual. Do you think somebody who is too lazy to read the user's manual that came with his/her car will understand how to properly maintain an automatic transmission?
Cars are more complicated and require more specialized service than before. The entire repair manual for a car from the 1980's could be contained in a 200-300 book. The repair manual for a 2010 Toyota FJ cruiser is ~4000 pages. Just the transmission section is ~300 pages long. Do you think that anybody who is not professionally involved in car maintenance will have the time and interest to learn and follow manufacturers recommendations and specs for correct maintenance and repairs?
This is a classic scenario. An owner checks the transmission fl uid. He does not understand the difference between "hot" and "cold" marks, does not know if the level in his particular car should be checked with the engine stopped or idling, etc. He concludes that the level is low and dumps 1/2 quart of a "high quality" transmission fluid he bought at a $0.99 "special" at Walmart. Consequently, the transmission starts giving problems while the car is still within warranty period. Now the disgruntled owner demands warranty repair and won't accept manufacturer's reply that the damage was caused by using wrong fluid. Of course he doesn't want to acknowledge his mistake and pay for the expensive repairs, so he goes to the social media, press, etc. to voice his outrage. Lawyers just love this kind of issues. The resulting mess - bad publicity, potential lawsuits, etc. - is just too much risk for companies to take.
Thanks for your kind words. A short disclaimer. I am NOT an automotive engineer and I am not professionally involved with any car company at present. I am mechanical and electrical engineer with 25 years professional experience in other industries. I am a car enthusiast and I consider myself reasonably versed in automotive technology. So my comments are just a personal opinion.Katekebo:
You seem to know a lot about car engineering. How long do you think this sealed transmission is good for? Like do you think it could go 200,000 or even 300,000 miles without any maintanence?
Flushing in NOT the Answer: BOTH THE FLUID AND THE FILTER need to be changed around 30-60K Miles (lower # if mostly City Driving). There are many YouTube Videos out there. Not just Toyota ... Sadly, many Mfgrs. are jumping on the "Sealed" bandwagon. Us users aside, most Sociopathic Vendors would like to just have a timer in every car ... at 100K Miles, it just self destructs. In a Nutshell: Tip: If no previous leaks, you can drain, capture and measure ALL of the fluid when things are just warm or cool. No need for being level ... just sort of level. Clean everything and replace the filter. Then replace that amount of fluid with Toyota ATF WS. The trick as many know is how to add the new fluid without losing your mind. I personally am looking into adding the new fluid directly into the pan ... while it is "hanging" with ALL the bolts in about 1/4". The gap will then accept a small tube and it would not take long to add (e.g. 3.5 Quarts of fresh fluid) ... a bit like an I.V. for your Transmission!The new Toyota innovation is to seal the automatic transmission after filling with full synthetic auto trans fluid. This does not allow the owner the possibility to check the level of trans fluid, or condition of the trans fluid.
I was not pleased to discover this fact after purchasing the vehicle.
I keep the fluid in my other vehicles with auto transmissions as clean as possible, knowing full well the price of a new/rebuilt trans with installation.
I will deal with this situation, I think, by taking this RAV4 for a trans flush at 40K to 50K.
What are the opinions here regarding the sealed trans, and how to deal with it?
