Internal transmission failure/replaced radiator/replaced rectifier in alternator.
Driving down the street when white steam like smoke comes from under the hood. The smoke becomes dense and there is a smell of hot transmission fluid. The vehicle begins to power off and upon exiting the vehicle there is a strong smell of transmission fluid and a large pool of fluid discharged under the vehicle. The car was towed and returned to the dealership. The dealers technician reported, "technician performed visual inspections and clean off of fluid found the transmission cooler lines at the radiator had disconnected due to not be improper connection issues reinstalled both transmission cooler lines and clamped lines, tested pressure on both lines. Filled system and test drove and cleaned (due to massive spray from lines coming loose), pulled vehicle back into shop and rechecked fluid level and cleaned area (repeated this process several times to bring fluid level to proper level) finish cleaning engine area and verified. Parts:6 fluid-atf +4". My issue is that I had just exited a high speed, 65mph, highway and if this failure had happened on something less then a slow secondary road with no traffic, there could have been a significant accident or potential injury.
