it started out on a wet 3 hour drive. I went through a clover leaf freeway entrance, about a n hour into drive. in the turn motor rpms went high and car slowed. as i intered freeway things returned to normal. driving at freeway speeds couldnt tell there was a problem. exit of freeway into city and car was really slow to move. rpms seemed normal. slowly parked it as it was barely moving and it smelled hot. not an engine oil smell but i figured trans oil. later drove it 20 min. home and it was impossible to park it. the trans oil looks clean and not burnt on inspection. I'm guessing it the gear box but assume it easier to replace whole thing. thanks again
