I got my tranny replaced and it had 90K on it. I took off my heatshield (big mistake) a while ago because it was rattling on my mid-pipe, but I put it back on today. I figured that the reason my shifter was sticky was because of the heat it was exposed to. To make a long story short, it's still acting up. Hard to shift into 2nd and 4th; should I get new bushings or short shift kit or what??
