i have a 95 camaro supercharged z28. it has a 6 speed ls1 trans. when i bought it, the owner said he broke 5th & 6th gear. he said some pin came out because you can switch into those gears, but its the just like putting it into neutral. the car doesn't drive in those gears, and it doesn't make any noise. anyone know what it night be and how much it costs to repair?
