Great article ...with the exceptions of few things...
Engine breaking at 30 and 40 km/h is actually a key feature in these transmission. ...if someone doesn't like it say (in a traffic jam) simply switch to S mode...then you won't get any engine breaking.
Secondly. ..it's really annoying how the information on these transmission are not readily available.
Thirdly....the transmission you showed was using a toyota tc genuine oil..
Red wala......which is a crap oil I must say..
Issue is this oil creates froth (jhaag) as the transmission moves...which reduces oil supply to various components. And it doesn't providing much cooling either...cause if you drive your car hard the transmission will give this winning noise.... (aeeeeennnnn). This only happens when trans overheats...which means there is Bad wear protection too ..cause of genuine Toyota oil...
Also bad oil or this toyota oil in hand will reduce your acceleration ...cause transmission (power losses)...your car puts less hp than written on your user manual.
Use liqui moly atf 1400 ....and you want have to do all this crap ...and you won't have dirty finger from the magnet....cause it has a better wear protection..
