Of all the threads I`ve read on this the fluid change is not instant but gets better as you drive it. So I guess you`ll find out soon. I change my fluid once a year so I never have had the shudder. 
My baby is hurt
2008 FJ Cruiser 200K miles automatic transmission.
I have a shudder and it's drivetrain. All week I have started to notice a faint but growing growl. Then yesterday the shuttering started to become unmistakable shake when accelerating and decelerating. As I coast to a stop I can click my automatic transmission over to neutral and shuttering stops completely. Staying at a steady speed is just as smooth as can be.
I was hoping it was a differential issue so I changed the fluid tonight and it was old and stinky, but no metal flakes at all.
So here I am and I think I'm looking at a transmission or a transmission part. It almost acts like a clutch, but they don't have such a thing on an automatic transmission, do they? Torque converter?
What do you guys think?
