138,000 Miles and the THIRD engine in this car (2 replacement engines). I have owned this car for 5 years and it has been nothing but trouble. Went on a road trip this past weekend and the transmission started slipping when going over 60MPH. It got worse as the trip went on, but thankfully we made it home. Has anyone else experienced this? There are no engine warning lights on either. I read a few threads about a wave plate - reverse seems to be working just fine. I did notice the spike in RPMs occasionally when the slips would occur. Any help would be appreciated. I don't know what to do - it's just the latest in a long string of problems and throwing money away on this lemon of a car.
