My brother had the same thing happen. He was sitting in traffic for an extended period and the tranny puked up a little over 3 quarts of fluid. It was a very warm day. Found out the tranny cooler was plugged and this is how the new trannies relieve the pressure of fluid getting hot. Now that being said I don't know if this applies to you seeing his vehicle was a ford mini van. He got lucky because he did not try to drive it when this happened so the tranny was not toasted. That happened last summer and he has driven it every since with no issue. Hope this might help. Joe
