Well manual says 55k km or 2 years which ever comes first. The same manual says to check at 40k km (which obviously means even if 2 years not complete).
Please don't listen to people - you will be at risk!
The most complicated part of our cars (talking of Corolla) I believe, is its transmission! Costly to repair and replace. Changing at 2 years or on reaching the mileage earlier will ensure healthy long lasting transmission.
If you want to take risk! It is your personal choice and deterioration of transmission will happen at an accelerated pace! Be safe! Good luck!
