I changed the tranny fluid in my 91 Prostar 190 about 50 hrs ago. It is the powerslot. I have 650 hrs on the boat. Tonight is the first time the tranny seamed to slip. After blasting through rough water, we found some smooth water and skiied for a few hours. While heading back to the ramp, it seemed like the tranny was slipping for just a second about 4 or 5 times and only about 35mph. I slowed back to 30mph and it quit slipping. Does any one think I need a new tranny or just low fluid?
