I recently purchased a new TV cable from GM because I broke my old when I was pulling my trans down recently(oops, forgot to undue the bolt). When I looked at it I noticed that there were only 4 notches instead of the 6 on my old one....I thought this wouldnt be a prob....until I put it on....I have only been able to bring the light trottle shifts DOWN to 3000rpms...I'm afraid to see how high I would shift at WOT like this! What can I do? Did they give me the wrong one?
