Last took my00 uk out for a drive Saturday no hard driving just bumbling around.Started her up this evening and i couldnt select any gears,the car was stuck on the drive.Went back indoors for 15mins went back out and tried again BINGO all was ok,what the hell happend.Its done 1700 miles on a new uprated clutch /flywheel etc and never had probs like this before.Can anyone shed some light on this? what happend? The clutch pedal was ok,plenty of clutch fluid

Thanks
