Peugeot 106 rallye stuck sometimes in 2. gear
 

Hi guys
Went rallying this weekend, and 3. times when I went full stop (finishing line) the car was stuck in 2. gear
When I started next heat (Started in 2. gear) when it went up in RPM i could change to 3. gear and everything was working fine.

Any idea where to start looking? I will change the gearoil, but have no idea what to check next.
Gear linkages looks fine imo.
