I shifted from 2nd instead of 4th changed it back into place. but as i was driving the clutch was super shaky...... can someone tell me what happened? but about 15 mins later it went away..?

 

Can you be a bit more specific about what happened? You can only shift "from" the gear that you are in, so maybe you mean that you downshifted from 5th into 2nd instead of your intended 4th? If so you likely over-revved (search the forum for overrev discussions). How serious was the overrev? How long? Any other symptoms? When you say the clutch was "super shaky" do you mean that it vibrated like it was out of balance, or something else about how it engaged or disengaged?

I don't know that I'll have all (or any) of the answers, but more information would be helpful.

 

i was in 3rd gear and redline and shifted to 2nd instead of 4th. i was going 90mph then. It wasnt in for too long and was able to throw it back in neutral.
It might have kick back like 4 times at the most. I dont know if im over exaggerating but the clutch felt shaky as i hovered my feet on it and press down, Right before it engaged. but then it went away.

 

At a minimum, you need to get a compression test and leak down test done to see if there is an issue. Do a search on this subforum for overrev and you will see what has been recommended be done after a possible/definite overrev. If you were at redline in 3rd gear and shifted to 2nd, my guess is that it went well over any safe limits. Get it checked out asap.

Good luck!
