When I hit 4th gear the stick vibrates a little. It goes away when I change to 3rd or 5th gear. I'm hoping it's the clutch. Any suggestions?

 

Im getting the same thing. In 3rd and 4th at low RPS??

 

Just on 4th at low rpm. From 1-3 at low rpm there is no vibration. Maybe its the clutch, I don't know?

 

I have the same effect as well.

The shifter shakes some, but when I hit forth gear it shakes more. I think sadly something is wrong with 4th gear, like its worn down or something. I hope not but I think that may be the case.

 

i get the same thing with my sts. Im about tired of this tranny! Ive been it up enuff. Time to throw out the clutch, flywheel and tranny and get a new one! lol :P
