I guess I should have told you how to get the top off. Doesn't look like anyone else mentioned it, so here goes. You have to put the trans in neutral (not strictly necessary, but helpful), then get a rag, wrap it over the top of where the shift lever meets the transmission (to protect your hand mostly), press down and turn. Its kind of like a turn signal bulb, press in, turn a little ways and pop out. Also like a Dzus fastener, if you've ever heard of those.
