Does the slave cylinder issue only apply when you are using the H22 slave cylinder? I am doing an h22 tranny swap on mine right now and I understand what you mean about the difference in the h22/f23 slave cylinders. However.. I think you can still use the f23 slave cylinder on the h22 tranny. The stock f23 tranny comes with a small bracket that lets you mount the slave cylinder on to it, so you can just remove that bracket (two 12mm bolts) from your f23 tranny and use it on the new tranny. I haven't put the tranny on the car YET, but the bracket seems to line up perfectly, the tranny's are ALMOST identical. The only difference I found on mine is that piece where the speed sensor goes. On the h22 tranny, there are two hoses coming out of it (most likely coolant lines?) and the f23 one doesn't have any. I just simply removed it and replaced it with the f23 one though since I wasn't planning on hooking them up. Anyway, I'll let you know about the slave cylinder thing as soon as I get the tranny on there.
