I've done it in 12 minutes but I think the book time is about 2.5 hrs. Its quite possible that the problem isn't with the shifter per se but the connector. I've seen them corroded to the point that both needed to be replaced which is a huge PITA.

It's been awhile but I thought book would be just over an hour, hard part usually is the link clip, often I found easiest to do it all from above instead of trying to wrestle your hand up to the clip along side the trans. I believe this is plug and play.
