Gs350 AWD tranny oil change
Time to change the tranny fluid on my 2007 200k mile gs350 awd. The car shifts just fine but at this mileage i'd like to do it preventatively.
Is a simple drain and fill a safe thing to do? I've heard of some people saying there's a risk of dislodging sludge that can screw up the tranny. I also heard of some doing partial drains and refills (like 1/3, 1/3,1/3 over the course of a couple of months). Anyone with experience doing a fluid change on a high mileage gs350?

Drain and fill 3 times, with 3-5k miles in between. 4th time drop the pan and replace the filter. On the first take a simple with your finger as it drains and or with a tissue. Smell the fluid make sure theres a hint of red to the fluid. If its super nasty I would just leave that first fill, if its not bad then proceed with the others.
