My RSX has 136k miles on it, don’t know if transmission fluid was ever replaced so I’m planning on doing it. What would be the proper way to do it, drain it and just put in new fluid or give it a flush?

drain and fill would be the way to go

Manual or auto? Either way would work on an auto, but use only Honda ATF.
Manual is drain and fill.

It’s auto. Yeah I’ll probably just order a case of the Honda dw1, drain it fill it, drive a little, then shift it around to different gear positions and then drain and refill again. Should get majority of the old fluid out.

Whatever you do, do NOT drain anything until you confirm that the fill bolt (top bolt) can be removed, or else cannot drive because there would be no fluid.
Also, make sure when you fill, keep your car as level as possible, I mean front/back and left/right. You stop filling when it starts coming out, that's the concept = level.

This is what I do, but I don’t bother with the different gear positions. I drive around normally for at least a day and do one more drain and refill. Most of the fluid sits in the torque converter and needs to be cycled. Inspect the fluid and you’ll be able to determine whether or not you need to do another drain and refill. There’s also an atf filter that I recommend you replace as well.

Is it an easy change? Don’t need to drop the engine right 🤣

It’s easy-ish haha. It runs along the front beneath the intake. I took off the front bulkhead and squeezed past the radiator, but you should be able to do it from the bottom.
Make sure you replace the drain plug washer too. #90471-PX4-000
