Yes you can, there are a lot of auto ludes with the h22a1 and h22a4. Worth it? How much does the thought of a tranny swap bother you? I love my H22a4, even with the auto. I could give a crap less if my auto tranny goes out, in fact I would probably be happy so I could swap a 5 speed in ($ and downtime would suck). I wouldnt have bought my auto but how many 5th gens are running around with 29k miles? I still take care of my tranny though.
Hope that helps.
