So today i took out the car for the first time since winter is over. I noticed that when hitting the clutch while driving to stop and shift, the pedal would be shaking pretty crazily. Never had this problem before. Before winter hit, i had a shop install a shep tranny. Also the clutch is a Exedy Twin HD. Any help would be great. It's quite irritating since my leg would be shaking as well, almost like its popping.

 

Bump, no replies? It shifts perfectly besides the shaking when letting up the clutch
