Transmission fluid change Options

[HaysoosKreesto]

Well, after a while of putting it off, I finally have some spare cash to change out the fluid.

According to some local shop's I've been calling, some of them do full flushes w/o cleaning the pan or changing the filter, some wouldn't even recommend a flush at all but instead cleaning the pan, new filter and new fluid, letting it run, then doing it again.

What would be the best way to make sure my car is safe? Should I go, new filter new fluid and clean pan? Or should I go flush and hope that any gunk just goes away? All the prices seem to be around the same ($110 - $150~) so I'm just looking for the best option for my car. Any thoughts?

Just got off the phone w/ Royal Purple tech support.... according to the tech, the Max ATF's broad operating range is 100*-to-220*, where 100* is the point were the fluid is warm enough to do its job and not be slow, and the 220* mark is where all of the heavy tow truckers work to keep there temps under, so he was using that as a reference.. he said that it was hard to say since the formulation for the fluid is made to be durable and help reduce heat and so its viscosity breakdown point is most likely a good bit higher than that... but.. that leads to optimum operating temp should be in the where abouts of 150*-160*.. posting this for anyone looking to do a proper setup with a temp-tripped, relayed fan across there trans coolers running Max ATF in there trans. or even if your not, but have a gage for it..

I'll post more progress once i get more done.
