What are your thoughts on the "sealed" for a lifetime transmissions on newer cars? Fluid that is suppose to last the lifetime of the vehicle in chemically decomposed states, after redundant thermal flux, moisture bond's with the PH turning acidic over time and losing their lubricating properties like you said by being diluted with contaminates. -Source

Seen 'em, done flushed where the fluid comes out looking like someone took a dump right in the transmission. Not only that but how will you even know if it's low, or burned up. Sealed trans can still leak. It's just another thing makers are doing to bring more money to mechanics and make it harder to DIY. At this point after owning 5 pre-OBDII and 3 post-OBDII(including an 06 I bought with 3 miles on it) I have fewer problems with the least amount of tech updates. I just prefer to know what's going on in my car with the fluids and sealed isn't the way to go in my opinion

E40D valve body exploded view

Not sure if they can be seen in this image but there are several check ***** the size of BB's and valves, all it takes is one flake of clutch material to get stick, not allowing the valve to close completely. I'll shut up now,

Im picking up what you're dropping but there's a filter in there for a reason, plus it runs a high enough pressure it would take more than what would come off anyway

I went to Amsoil atf about 60000 mile ago and it still looks like new, looks like the day I put it in.

For what it's worth, I've owned plenty vehicles over the 100k mark and had burnt transmission fluid (including my truck) that didn't die after I changed out the fluid. My thought is if the trans is dead, it's dead. I've never had a case of new fluid killing it, but I have had cases of new or higher quality fluid eliminating shifting problems.

I'd be cautious about flushing an E4OD. The filters are known to come off by themselves (There is nothing to hold them on except an "O" Ring. The flush (I am told) flushes the system in reverse of it's normal fluid flow.

Drop the pan, replace the filter and gasket. What can that hurt? Regardless of what I or anybody else advises, talk to your transmission man. A reputable trans shop will give you accurate information.

EDIT:
I almost forgot. A lot of shifting issues on E4OD transmissions get traced to the switch on the side if the trans by the shift rod. It's a $50 part. I'd change it, just for giggles. You'll probably need a new one for the new trans anyway.

Ford recommends the addition of a small magnet under the pick-up portion of the filter to hold it in

Flush=bad, fluid and filter=good.
