I've got 500+ miles on the Cobra now, and while the shifter is getting better, it still hangs up between gears, and feels like the synchros are very stiff. I'm used to other manual transmissions having a nice smooth "snick snick" going between gears, and am disappointed in how clunky the 6-speed is on this car. IMHO it's not the shifter but the tranny itself. How long did it take your cars' shifting to9 smooth out?
