at every 15,000 miles or every 3 engine oil changes (whichever comes first) on every automatic I own I change the fluid and filter, and if applicable adjust the bands/cables/position sensor.
Only after I burned out a transmission did I learn about that. I changed fluid at every 25,000 miles approx.
Put it this way:
One of my friends has a Ford 1 ton truck, he's changed the fluid and filter and adjusted the manual lever position sensor every 15,000 miles.
It's a entirely stock transmision, never been flushed, it has over 1.5 million miles on it, never been rebuilt, still doesn't need it.
He tows heavy loads regularly with it, and it's his daily driver.
He has no reason to lie about it either.
The same goes for the Dodge transmissions, Chevy transmissions, any automatic. Keep it cool and give it plenty of clean fluid, and it'll last forever (almost lol).
People complain about these Dodge transmissions failing all the time. While they could have been built better, both me and many other transmission shops noticed one thing: Changing the fluid at the factory recommended interval is usually NOT frequent enough to keep the fluid clean. Even if that fluid smells fine and looks fine, it's got lots of stuff in it you need to get rid of, and the chemicals in the fluid don't last forever either. Electronically controlled trannys depend alot more on the chemicals in the fluid than most people realize.
That stuff causes sensors on our electronically controlled transmissions to read improperly, and it also clogs/limits the proper operation of the governor. Essentially this causes the transmission to run out of spec and causes excess slipping and poor operation which adds more deposits and builds up heat leading to premature failure.
Then it's only a matter of time til it will fail...
Any rate I don't want to derail this thread...
