This week on Car Talk, Dana's Jetta is shaking violently in 1st Gear. Could the culprit be the dreaded (and highly technical) "schmutz on the clutch?" Meanwhile, in Dallas, Dr. Paul's life has been a Country-Western song: he totaled his car, his wife left him, and his dog died. Can Tom and Ray help him choose a new ride that will help him find a new love---and a new dog? Also, Science Museum educator Seniz needs a lesson from the space shuttle to understand the noise her Civic is making; Mark has discovered a new driving technique with the double bonus of being more efficient and making his wife thinks he's completely nuts; and on Stump the Chumps, did one answer solve three problems for Ed and his Jeep? All this and lots more, this week on Car Talk.
