ACtually, in the 05+'s, it isn't the transmission that sucks, it's that crap-assed hydraulic clutch. It won't release fast enough to power shift properly. But, add the MGW shifter to it and it gets the job done quite nicely. It's a shame that car was so ****ed heavy, but it was an absolute blast to drive.
Matter of fact, anyone want a Scoshe enclosure for the 05+? I still have mine that I'll part with cheap. I don't wanna just toss it or anything, but I'll certainly cut a deal on it to get it out of my garage.
