my 05 wont shift above 6k, its like somthings blocking it, but when it drops down around 4500 it slips right in. it did this with the stock shiffter so i got an mgw and it still does it.
Mine are modded very similarly to one another, but the '05 is the one I had the issue with getting into 3rd gear with. I don't know, it may be more prevalent in '05s. Either way, even stock or with basic bolt-ons, I've noticed this issue with the '05. The shifter resolved it for me, for now. But I fully plan on replacing the k members on both with built-in motor mounts and torque limiters.
