If you can pull the tranny yourself, you'll save $$$. The biggest problem is getting it out. If the problem is the clip, it is simple to fix. I had the same problem, but eventually lost reverse also before I pulled the trans and found the misplaced clip. Reinstalled the clip and had 5th and reverse again. But like I said, getting the tranny out is not fun. Most of the cost is extracting and replacing(labor).
