i was driving home last night from hockey and i was going about 80 mph,...all of a sudden my car starts jerking so i turn down the radio and i'm like wtf....about 10 seconds later i smell a horrible burning which smells like gear oil....i get off the next exit and pull over....nothing leaking...everything looks ok...so i drive the rest of the way home (about 10 miles)...when i got off the exit at home i slowed down to a stop light....everything seemed fine...then i took off and all i hear is my gears sounding like they are clunking around in the differential....but the thing that gets me is i just changed the fluid and it hasnt been leaking so i know there is enough in there....any ideas what this could be?...i wont get a chance to tear it apart til this weekend so i want some things to look for
