yesterday my mom took the car out to the store and said she heard a loud noise form the engine. the car would not move at any gear. there was a large puddle of oil or something under the car when I got there. now wjen I turn the car on theres a loud rattling sound. someone said that the cv joint may have broken but I think it may be the transmission. I have a 01 v6 with 110k miles. the atf was brown when I checked it also.
