Transmission is leaking, dripping fluid on exhaust system which is creating burning smell and at times some smoke. Fire hazzard? the original transmission failed at 29738 miles and was replaced under warranty with a 'used' unit (mfg term is remanufactured, which equals a unit that already failed for someone else and was rebuilt). The replacement unit has only 10,000 miles and is leaking in two places.
