Answer
Scott,
Slipping transmission could be caused by low fluid, dirty filter or just a bad clutch. I would have a transmission tech take a look at it. They can test it and tell you if its bad or not.. I would in this case get a few estimates on a rebuilt transsion, or a new one.. But I wouldnt make any decissions yet as transmissions are expensive... Thanks..
