Hi everyone, I hope everyone is doing well. Long story short my mechanic just told me that my 07 4wd 149k pilot is leaking AFT fluid and he also said that to stop the leakage he has to remove the transmission and replace some seals. My question is if the transmission is removed does the entire AFT fluid & transfer case gear oil has to be removed as well? Please excuse my ignorance! I read that flushing the transmission fluid could be dangerous. My only concern about this is that the transmission fluid was never changed by the original owner for 130k miles, in fact the ATF fluid was quite low and dark when I bought it off him I added about 3 qts of new fluid to bring it to the correct level. My mechanic is not concern and told me that the transmission runs great and i shouldn't worry if we flush the ATF fluid and add new one. My pilot drives very well no transmission issues at all. The leak is not mayor but it's visible and coming out between the back of the engine and the transmission. Again I read and saw multiples videos on Youtube where some say don't flush the transmission fluid because it could create problems how true this is???? Have anyone experienced something similar? Thank you in advance.
