Son has '10 Avalanche w/94K miles. To my knowledge, its never been changed. He doesn't off road it or tow, but its creeping up on 100k.

Change filter after doing a drain and refill two times.

I.e., change filter on the third drain-refill.

Does that transmission have a drain plug? If it doesn't, get the Dorman pan that has one.

I should change the transmission filter on my 2005 avalanche. As far as I know its the original filter. Just rolled over 190,000 miles. I have siphoned and filled it several times . No transmission drain on my 2005. Does anyone have any experience with the Dorman pan? I might get around to it this winter.

The Dorman pans got middle of the road reviews on Amazon. Probably weld a drain plug in my pan when I do this job.

B&M aftermarket plug in my 4L60e pan - $10 or so - toss the nylon seal and use copper washers - on my ramps it drains 4 quarts clean and easy - once you put a new pan filter in - just do that a couple times and then once a year during oil change ...

I generally do fluid every 50k and fluid/filter at every 100k. I tow quite a bit and the fluid always looks good. I could probably go closer to 75-100k but it makes me feel better. Cheapest Dex VI I can find (usually Supertech). Never had a trans problem ever.

So would you guys pump it out and not bother with filter or change out everything.

That truck has the six speed in it, correct? Not only should he change the fluid and filter, he should add an auxiliary trans cooler if it doesn't already have one.
My 2009 Suburban has had the fluid and filter changed at 9,000 miles (when I bought it), 50,000 miles and 100,000 miles. At around 125,000 miles, I found the fluid was brown and burned. I had the trans shop flush and service. Last month, at 139,000 miles, it wasw slightly burnt again. Shop flushed, serviced and added a factory cooler. Inside of the trans looked ok.
With the cooler, as small as it is, the trans temps are nice and low, like 174 degrees at 70 mph on a 78 degree day. Fluid seems to be lasting fine. We'll see as I rack up some miles.
I'd like to hold off on a rebuild if I can as it costs about 3500 dollars.
Also, tell him to drive that truck around in M5 and not D. It keeps the engine in V8 mode and not that stupid four cylinder thing that fails and destroys the cam. I drive mine in M5 all the time and it runs great.
My brother's 2007 Tahoe had one of those controlled intake lifters fail. It destroyed the cam. You have to remove the heads to change lifters in that engine so we swapped the entire engine. We replaced the four DOD lifters with regular intake lifters and he had the system programmed out of the computer. Truck has been stellar ever since. He drives it every day as it's his work/ family vehicle.

The only other helpful thing I can think of is change the plugs and wires if it hasn't been done. The rear passenger side one is a beast but it really makes them run sweet.
Also, keeping a fresh air filter in it makes a small but noticeable difference.

Sorry for resurrecting an old thread,but can anyone explain the merits of doing this please.I had heard of it before when changing the ATF in very old transmissions,but i don't recall the reasons as to why,or why not.(I am genuinely interested)

I, myself , have changed my policy after seeing too many good transmissions that were just disgusting with the metal sludge in the pan. Nothing was wrong with the transmissions. All went on to live long and healthy lives. It's just that over 80k+ miles, these things shed a lot of metal, and I'd rather clean all of that out than leave it running around in there.

Magnets need to be cleaned as well in order to stay effective. When you do a drain and fill, none of this is being taken care of.

The “sludge” is metal? I thought that was clutch material?
