There are two transmission line plugs from Dorman that say they are compatible with my Chevy Trailblazer. Based on reviews, it was difficult to determine which transmission line connector would be an exact replacement. I broke a clip on my old one and found that replacing the whole connector was cheaper than buying a set of clips. I took a chance and bought this one and it fit perfectly and replaced my 2005 Chevy Trailblazer LS 4x4. Replacing the plug took no more than 5 minutes.
