Is Changing The Atf Fluid Really This Easy?


Recommended Posts

First of all assuming the RX autobox is a similar setup to the IS...

Seen loads of ppl say its a professional's job, but it doesnt look any different to changing the engine oil to me! was thinking of doing it with next service as my fluid is slightly brown ive noticed

Only problem I can see with his approach, is that any fluid in the gearbox internals, torque converter and cooler (and associated pipe work) isn't flushed out. It will just mix in with the 4 quarts of fluid he replaced with the sump drain (no idea on the full capacity of the RX system, but that would give an indication of how much old fluid was still left in). I don't class the job as a pro job, but there are better ways to make sure you swap out the fluid in a more thorough way.
