Just ordered $400 worth of tranny fluid, pan/gaket/filter. Will be doing first flush at 63k miles on my 05 HSE. No problems so far. I am religous with the diffs. I had the rear diff replace about 3k miles ago and just replaced the fluid. It was amazing how much metal particles were in the fluid and thickly covering the magnetic drain plug after only 3k easy miles. All diff fluid to be replaced every 7500 or so miles from here on out. Trans will be every 20k or so from now on.
