I did this on my taurus and did not spill a drop.
Filter change + fluid exchange= happy transmission.
Agree with filter+fluid... would actually do a fluid drain refill, THEN a filter+fluid swap, so you'll get 2/3 of the fluid changed.
I've seen stock ATF+4 come out looking pretty good at 60,000, but still think it's useful life can't be much more than that.
But I don't know if Chrysler AT's can be singled out so simply. The problems were not engineering problems any more than Honda, earlier 'yotas... but management problems... 1) stupid "lifetime fill" leads to failures. If folks changed the fluid, the AT would last longer. 2) the old minivan AT failures was a result of chrysler stating non-ATF+3 being just fine, which it wasn't. folks that stayed with oem fluid specs had "in the curve" lifespans for their AT's.
I towed beyond my minivan's rated limit with the 41TE, without an aux cooler, and never had a single AT problem. bought it used and put over 60,000 miles on it, and yanked a 3000 lb camper through the mountains west of MD.
We have an LHS, highly abused, in my ex's family... ATF changed once, passing 200,000, and the AT will likely outlast the engine (highly neglected). They have a second LHS, that never sees maintenance, at 100,000, shifted smooth as silk the last time I was in it.
Yea, they were commonly bashed for failure, as they did fail often, but I don't know how much was from poor engineering, vs poor maintenance guidelines. The Ram trucks had some bad runs for a couple of years too, but the RE series AT's is generally regarded as very sturdy. I've owned 2 jeeps and one minivan from them - knock on wood, zero AT issues.
