Sloppy Shifter Update
I know this is not a "which air intake works best" thread so bare with me.
Background: My car only has 17k miles on it. I could not shift into 3rd when racing.
Diagnosis: The rubber bushings that came on C6s looked worn out and the seal that held the shift linkage rod in place was split and not in the housing.
Fix: I intended to machine some polyurathane mounts from some suspension stuff I had left over. This however, did not account for the seal that was bad and I have yet to find one by itself. I had a C5 housing, (the thing your shifter bolts to with 4 bolts) lying around and noticed that the seal was in place and that the rubber bushings were aluminum. I inspected it closely and it was identical to the C6 save the rubber bushings. I took the C6 housing out of the car and although the bushings looked worn from the top, a close inspection from the bottom revealed that the area which was to mate with the housing was completely gone. There was nothing holding the housing from moving side to side. Also, the rubber deal on the bottom that holds the housing in that slot on tunnel fell off allowing further movement. I'm not afraid of vibration, I have a huge cam and a huge motor, so I used the C5 housing and no bushing. Just bolted it up tight. There is not much more vibration. There is indeed some, but not much more. The shifts are precise and crisp. I didn't think there was any way that stuff could be so bad in a car with low miles, but it looks like a poor GM engineering deal. If you have slop, especially side to side slop, check this out.
