Hi there,does it necessarilly need to change gear the oil in an Auto engine?I have got a Toyota Camry car that i have been using for 2 yrs and never change the gear oil cos it always remains clean anytime i check it,and its working fine.However,my mechanics just advised me that i change the oil eventhough,it still looks fine.I would appreciate it if d engineers or anyone in d house with better understanding of d issue could put me through.Thank and God bless!

Yes, your ATF needs to be changed @ least once a year or depending on the mileage you cover within that period. It is essential to use the appropriate ATF for your vehicle. Since you bought the vehicle, have you changed the ATF? Or do you have the service history to confirm when last it was changed?
Might also be handy to know if your engine is driven by a timing belt or a timing chain, if it is a timing belt, @ what mileage was it changed? Was it only the belt that was changed or the pre-tensioners and the water pump? Etc etc etc
All the above plus more are important factors, if you want your car to serve you more on the long - run.
