He just bought this van for $2500, as is. It seemed to work perfect for a week or so but now, when he hits about 60 kph it seems to chug a little bit and he thinks the tranny makes a clunking sound as it changes gear. That's how he explained it to me. I told him I would try and find out what's up. Its a Dodge Caravan, 3.6litre, 94 I think. Is his tranny going?
