OK, I'm glad (and sorry) to see some other post about this. I have a 95LX with the 2.5/ATX and I too had trans fluid spewing out of the vent hose after the dealer over filled it. The fuild was toast as well! And it had only been a couple thousand miles since being serviced.
Anyway, this tranny has been very hard on the fluid. The main symptom has been it not engaging when cold. Doing a flush and keeping the fluid fresh kept the problem under control until last week. It started again suddenly, and real bad. I did a 16 qt flush and it was/is totally dead now. Only engages briefly when the engine is revved. Due to economic reasons I'll be fixing this my self. I'll be sure to post the results.
