Looking to change the automatic transmission fluid on my 2005 Lexus RX300 and the Owner's Handbook lists the capacity as 3.5 litres for a drain and refill. I'm assuming that that figure doesn't include the fluid that would be in the torque converter, so my question comes in two parts:
- if doing a full change, does anyone know what quantity is required?
- Is it better to do a full change or just a drain and refill? Or maybe even to do a drain and refill, run it for a few thousand miles then do another drain and refill?
