That's been my luck. I think the seals get lazy when the fluid pressure falls off because of a dirty filter. Once a nice clean free flowing filter is in place, too much pressure blows the seals internally. That's just my opinion. I'd change the fluid more often than 30k. I'd put a drain plug in the pan and change it about every 10K just to keep good clean fluid in place.

Tranny fluid breaks down with heat and we have pleanty of that with the climate and heavy trucks. I change mine once a year about 10K miles. This is cheap maintenance for what a transmission cost.
