Im in shock no one has ever heard that before? Ive see it on the forums many of times, had multiple transmission shops tell me that, and seen it happen first hand on my 47re, not only that but my father who was a mechanic for years saw it multiple times. Doing a tranny flush will most definetly open a can of worms on a high mileage transmssion if the transmission was neglected on fluid changes. Surely im not the only one to know this?

Never heard it.
All the settling I'm aware of took place around that nifty little magnet they thoughtfully put on the bottom of the pan. Attachment 35957

Cummins detuned al 5.9 Cummins told me the only thing holding the 5.9 back is the Dodge truck

For sure, but the stick is a bit stouter than the slushbox.

Ya, but I thought the auto engines were detuned even more than the sticks...

Turn up the line pressure a bit in the valve body; better yet get a shift kit. Make sure you call the company to get what YOU need, look into governor springs and valve springs. Biggest bang for the buck. Won't harm the trans either. Grind yourself a 100 fuel plate and keep in stock location. Do a BAHF and straight pipe/Hiflo muffler and lately bump the timing to 16*. I'd call it a day and after that if your not ready to drop a grand on your trans.

I agree, if you've ever taken apart an auto you'd never do a " flush".
