I know the answer but want your opinions......
On my ford 4R70W, 4R75E variants, I have never caused a failure by changing the fluid and filter. Even when the fluid was poor.
I have a 42RLE in a dodge nitro, and with 150k I do not know the history. It shifts perfect but I experianced a neutral flare after a very sharp right had turn. I think it sucked air from the super aggressive turn and it being a touch low. The fluid is a brownish motor oil color and smells stale, not burnt! I heard ATF+4 does not retain its color dye very well with age. And acceptable fluid can look bad and not smell burnt.
I want to pull the pan, and unless it is covered in clutch debris change the filter and put in new fluid for however much came out, and call it a day. I do not want to do a "flush" or multiple fluid change with that kind of mileage and condition of existing fluid.
Is this ok, or is this tranny sensitive to fluid changes washing the debris into the valve body and damaging the rest of the transmission?
