Kind of see both sides of this one. While my wife and I were dating, I started to teach her to drive my Nissan pickup. Bad idea. It all went well until she stalled it at a light and the guy in the Winnebago behind us spent the entire light cycle pulling the air horn. Then the sheriff's car pulled up next to us when we were switching seats b/c he thought we were goofing around. (All I had to say was "Teaching her to drive a stick" and he laughed and drove off). After we got married, we bought a 5 speed Civic b/c the price was right and we needed the mileage for long commutes. Trying to teach her to drive that was the first REALLY big fight we ever had. (BTW - no matter how poorly she's doing, "Are you trying to wreck the transmission?" is always the wrong thing to say.) With a little help from someone other than me, she was fine. My dad says married people should never 1. paint a house together 2. go on a canoe trip (no spam!) and 3. one try to teach the other to drive a stick. So far, he's batting 1000 on that advice.
Seems like I read somewhere a page or so back she has a friend with a stick, have her friend teach her, be done with it.
Cliffs: Get someone else (preferably another woman) to teach her.
Or buy a Miata, those are about the easiest manuals in the world to learn on. (See, the answer is always Miata).
