i was drifting and as i was leaving my transmission started being really loud and i smelled a burning something. it smelled like a caliper, or break pad burn smell, but it continued on as i drove home. when i got home i popped the hood and check the coolent to make sure it wasnt my motor that was burning. after snooping around i found out it wasnt my motor. does anyone know what this burn might have been. it wasnt my clutch either. thanks.
