I just recently bought a bullet torque converter 3500 stalll for my camaro z28 but it doesnt fit? and the performance people says it is for a 4l60e transmisson which my car have but it does go need help!!!!!!!

When you say it does not fit... What exactly do you mean? You have not given us enough clear and concise information to be able to assist you.

First, have you ever installed a T/C before? If not, you should not be doing this alone.. Get someone who knows what they are doing to assist you. There is a special technique to installing a converter. Doing it improperly can, and will, destroy the gears in the pump.

"which my car have but it does go need help"

WHAT DOES THIS MEAN????!!
