I want to drain and flush the ATF on my 2010 Fit Sport. I will first drain and fill but I also want to flush the fluid from the torque converter using the hoses that run to the radiator. However, I'm not sure which hose to remove, the passenger side of the driver's side hose. I want to remove the hose and stick it into a quart bottle and remove a quart at a time by starting the car and stopping it when it fills the bottle.

What I'm really wanting to know is which hose flows fluid to the radiator and which hose flows out from the radiator.

I believe the passenger side hose is the flow into the radiator, but can somebody please confirm?

 

Well, it is the passenger side. I flushed out three quarts per CasualFitOwner's instructions - it was very easy. It's now done and it does shift much better and smoother now!

 

I've been thinking about this too at 55,000 Miles, but I think I'll play it safe and just do the simple drain-and-fill routine and then repeat it in perhaps 10,000 Miles. I've purchased the AT filter and will replace it too just for the heck of it.
