Yup, did it a month ago. I jacked up one side of the car, climbed under, found that the hard rubber grommet directly under the shift lever had disappeared. Farily easy to see and access. I removed the safetly clip, lubed the new grommet, and with a little fiddling with a large blade screwdriver, forced the new grommet into the hole. Replaced the safety clip and bingo, problem solved. There were a few more details, but if you climb under the car with a flash light, you will most likely see and understand the problem quickly. The grommet cost me a dollar. Time spent, less than an hour.
You can call me in San Diego if you have questions: 760-434-8858
Hope that helps.
