Do you have cold start stiff gearbox issue 5sp Manual?

i get the same thing in my s2000
you just have to take it easy and make sure u shift properly and not try 2 shift fast or lazy because you can crunch very easily aswell

Yeah its fairly common, especially on really cold mornings. Its called 'cold shift baulk' . There are oils that claim to reduce it (they contain additives or are synthetic).
