Ha! I'm the last guy to do a patch job; I was under the impression that this was a hi tech solution to a factory weakness in these cars. I'm not old enough to remember first hand but was aware of a recall/warning about these cars captured on film going in reverse by themselves and trundling down the street without a driver! My understanding is that anything less than perfect condition in detent and linkage setup results in the problem of jumping into gear. Am hoping to eventually go through the forum and pick up tips on how to fix properly.
