BRO THIS IS EXACTLY HOW YOU DO NOT CHANGE YOUR TRANSMISSION OIL. THIS IS WRONG ON SO MANY LEVELS. PLEASE DONT POST SOMETHING UNLESS 100% CONFIRMED.
some background.
nowadays toyota is giving all its new cars sealed transmissions. these are not meant to be opened and their fluids drained, even though you can change them. to change or check the level or color of liquid is exponentially difficult than an older car with a dipstick and a simple drain plug. they made it very difficult because they say that the transmission fluid is "lifetime". i do not agree with them, along with the majority of the gearheads out there.
first question: when do i change the fluid?
answer:its controversial by mileage. values ranged from 30k km all the way up to 120k km or even lifetime(as toyota says). the best way to check if your transmission fluid should be changed or not is to see the color of the fluid. if it is transparent, red, pink, magenta, purple, light brown, brown then it is ok. if it is dark brown then it should be changed, but no hurry. but if it is black it should be changed immidietely.
second question: how do i check the color of the fluid bro?!??! i checked and there is no dipstick bro?!?!!?
answer: yes there is no dipstick, but i have found a successful jugaar to check the color of the fluid. make sure the car is cold. touch the engine for 10seconds and if you dont scream then its cold.grab a CLEAN drinking straw(yes the one with which you drink pepsi/coke) and open the big nut that says TC on it.it can be accessed from the left tyre if you turn the car to the extreme left or from under the car. after you open the TC bolt, take the CLEAN straw, double check its clean, not a speck of dirt should be on it. insert the straw inside the nut and when it doesnt go any further, take it out, and clean it with the tissue paper. the color of the fluid on the tissue paper is what you should be looking at.
third question: ok bro my fluid is dark brown or black what i do now bro????tell huh????
answer:ok so now you have finally decided to change the transmission fluid. to change the fluid first make sure the car is cold. then make sure it is level, and not tilting in any direction. then open the tc bolt. now under the car there is the transmission fluid pan right next to the motor oil pan. there will be a 6 hex bolt under the pan. using a breaker bar hit the ratchet, dont use gradual force, one forceful hit. when you unscrew the bolt, no oil should leak if the car is cold and some fluid (approx. 1/2 litre) will leak if the car is warm. let it leak if it does. collect the fluid, it will be used to calculate afterwards. now when the oil has leaked(if it has) then take the same 6 hex and inside the hole you will find another bolt of 6 hex(boltception) open this bolt with your hands. dont use ratchet since it is plastic. this will unscrew the 2inch pipe and all the transmission fluid that is collected in the pan will leak. collect the fluid. after all the fluid has leaked, put the pipe back inside, screw by hand, dont use ratchet at all, even at the end. then put the screw back and tighten it by normal force of ratchet. now put all the transmission fluid in measuring containers(like empty motor oil bottles) and find out how much has drained. now use HONDA CVT TC oil of the same quantity(pre measured) and put it in the TC bolt. to put it in, you will need a special funnel with a long narrow flexible pipe at the end. you can create something homemade but you will find a proper tool in the hardware shop. when all the transmission has been poured, close the TC bolt. now, all the transmission fluid has not leaked. almost half the fluid is retained in the gears(or cones). after you drive about 100 km, repeat the same exact procedure. 2 flushes are good even though not necessary. i usually go with the 2 flush method.
fourth question: but bro what if i dont trust my current transmission fluid level in the car. what if some leaked or if a mechanic screwed up and idk if he overfilled or underfilled the fluid. basically how do i check the level of the fluid???
answer:ok.....so this is where it gets tricky and where the 2inch pipe comes into play. in order to check the fluid level, you will need one special scan tool. any normal base level scan tool will do i think. ok basically the thing is that transmission fluid has a special property that it will rapidly expand and contract with temperature. it expands with heat and contracts in the cold. the 2inch pipe is basically an overfill pipe ONLY WHEN THE TRANSMISSION FLUID TEMPERATURE IS 104-113 °F. a scan tool will used to check the temperature of the transmission fluid. the method to do this is basically start with the cold engine, take off the hex screw but leave the pipe inside. fill fluid in the TC bolt until fluid starts draining(so basically you have overfilled since the car is cold).start the engine and wait until the scan tool shows the reading of the transmission fluid temperature(TFT sometimes on scan tool). you will notice the fluid will magically start to leak again out of nowhere. this is because the fluid temperature is increasing and it is expanding and leaking because of its now higher volume. when the temperature on the scan tool reaches around 110 °F screw the plug. your transmission fluid is now level. congratz. idk why toyota has done this but it has, and i have told you the way to check fluid. please feel free to ask any questions i am available. and ready to answer. for those of you who have opened their pans by following this genius, not too much harm but make sure you check level according my method
