My RX300 takes approximately 4 quarts of fluid when I do a drain and refill. I think it may call for 4.2 quarts or something like that in the manual.
The transmission drain plug takes a 10mm hex drive to remove it.
You will also want to replace the crush washer (metal gasket) when you do this so that you can be sure to prevent leaks.
The RX calls for Toyota Type IV and that is all I have used.
Hi Tom,
Thanks for the good info. I picked up the tranny fluid today from the Toyota dealership. After you have drained the fluid from the bolt under the car, where do you add the new fluid?
Thanks,
Mark
