I get a wierd kinda double thud harsh shift every now and then from mine, as if it decided in mid-shift to change its' mind. Its been like that since it was new. I ignore it. When it happens, it feels like the older ones felt when the roll-restrictors were broken. Like the drivetrain is pitching back and forth rapidly, rebounding from the shift. But it is not. The mounts are all solid. I'm not worried. Did the first tranny service at 112,000, all was good. Minor fluid discoloration and minimal debris in pan.
