Hey i think there is a problem with my auto transmission (97 EL six)! Yesterday while driving it around, first off i dunno if it was the trans or not it was making like a high pitch sqeel! It kind of sounded like electrical interferance you get when you have amp and a fully decked out stereo! After driving my misus home, then first gear slipped twice (like putting the car in nutral) then the third time it made a grindish type noise! After that the i drove the car home while reving it much, and i didnt want to push it! I got it home without much trouble. Can it just be it needs a service or something or do you guys believe its much worse? Is so how much would it be to fix?
