My series 2 gtst isn't going into gear while engine is running. Clutch pedal feels like the pressure is gone and is spongy . Looked at fluid levels on the master cylinder they are fine. Slave seems to be operating correctly. If started in 5th with clutch out it stalls immediately so I think clutch is ok. I'm thinking the clutch fork maybe ? Or the ball joint thingamajig. Clutch wont engage when engine is on..Any suggestions or anyone had the same happen.
