99 R50 Transmission Pan Seal keeps blowing

[SnowSurfLax]

I really need some insight here, I can't figure out what's going on.

So, 2 years ago this month, I blew the transmission pan seal. Leaked very slowly unless fluid got really HOT. Got it fixed: flushed, new seal, new filter, etc.

Worked fine for about a year. transmission starts slipping, BAD. Had to turn around and even then as I was working my way to the shop could barely get it to stay in 2nd for more than 30 seconds. They looked at it and told me they added an "additive" and then it drove perfect again. GOt it flushed about a month after that.

Cue to 9 days ago. Blew the transmission pan seal AGAIN. Haven't gotten it fixed yet, the fluid loss basically only occurs when it gets above normal operating temp.

Now, I don't do a lot crazy driving or offroading. I don't stress my QX to cause the transmission to have issues. Can anyone shed some light?
