MonteC, it would be great if you could post up a list of mods and best practices that would help the longevity of our 46RE's. I know my previous owner did a transmission flush service before, but going by what I'm reading here, I don't think I want to risk that again.

Hutch, Did notice a much firmer shift on low to mid throttle. Not any tire barking WOT though. My first complete rebuild with the help from this forum on what to do and not do. I was told that the quicker you get the cluthes engaged the less wear on them. Did find a bad sun gear and front bad, but everything rlse looked good for 93000 miles. Replaced converter just to have peace of mind knowing no crap would come out and mess up my rebuild. OD unit was in good shape even though it is suspect in many cases. Just a 2wd quad 5.9 truck that now is in need of a plenum gasket fix. With the info from here looks like not a problem. Thanks for asking.

Nope. It has nothing to do with the viscosity of the fluid. Your explaination actually sounds quite silly. Transmission fluid is basically hydraulic fluid, they share many similarities. In transmission fluid there are additives and detergents, to keep moving parts clean and the valves free. If you get a transmission with over 100k on it and no one has ever serviced it then the old fluid has lost all of the detergents and additives, they are all used up. So now all your left with is old basically hydraulic fluid.
When you do a flush service on a high mileage unit you break loose the crap that has built up in every crack and crevis in the unit. This crap floats around and hangs valves or clogs up the cooler lines.
If you do a simple pan drop and filter change and just add in new fluid to replace what came out of the pan you will help the transmission.
Please stop perpetuating myths. I have never built a transmission that was serviced properly.

in my experience( im a tranny tech at a local chevy dealership, maby thats why), ive seen 700r4's come in with about 120k miles and they complain of slipage or absolutely no reverse/4th gear whatsoever and they have all said they've changed the fluid and filter within 200 miles. now, on the otherhand. ive seen 4L80's come in with 270,xxx+ for oil change/27 point inspection that have NEVER had the trany fluid changed and they still shifted almost perfect, minus a little delay on the shift times. Maby thats just with chevys trannys. im still learnin all this new confangled chrysler stuff not tryin to shoot down anyone, just what ive seen.
not tryin to shoot down anyone, just what ive seen.If they 700r4's have no reverse or 4th then its a good chance the sunshell is broken, nothing to do with fluid. How many 120k 700r4's are out there? They stopped making that transmission over 20 years ago.

Bud its all the same stuff. The theory and mechanics behind them are pretty much the same.

the sunshell was fine. the clutch packs were darker than our prez
and ive seen probibly about 6 or 7 that have less than 140k on them. i just put a shift kit in one a couple of weeks ago in a WS6 that had 81k on it...

I know that is all the same stuff. what im sayin is that maby these transmissions have a higher tolerance for sh!+ in them.

The thought that new fluid will kill an old transmission is well to be frank, pretty dumb.

They are a pretty good transmission once you get them rebuilt right. The biggest problem with this transmission was the lack of the publics knowledge on the TV cable system. These transmissions were super sensitive to the TV cable setting and people would either mess around with it and get the wrong setting or not get it adjusted for 100000 miles and burn it up from it being out of adjustment.
