i was going 2 work today and i was in 3rd and was slowing to make a right i pulled the clutch in and it sounded like there was somthing bouncin around in my engine and i shifted in second it just shifted with a little jerk what is wrong its still under warrenty so what do i do??

Not to sound like captain obvious, But take it back to the dealer!

sure you didnt hit a false neutral? it will make NASTY noises and even vibrations and then CLUNK hard into the closest gear these tranys are damn tough man. ive seen and messed with them and they arnt flimsy gears or shafts. even the shift forks are kinda beefy.
