I heard recently that the new automatic in the JK requires no filter or fluid changes for its lifetime. Surely i must have heard wrong. I have changed my truck and jeep trans fluid and filters at around thirty thousand miles and from the looks of the fluid, it needed changing. I suppose in a small vehicle this might be ok, but in a jeep or a pickup I just don't see it. Further if a seal begins to leak, there goes the farm. Am I wrong, or what.
