Sounds to me like a hydraulic issue. I would replace any hose first, as it may be collapsing on the inside. If that doesn’t work, it’s time to rebuild the master and slave cylinders. I would start with the master since I believe you may need to remove the tranny to service the slave. Maybe a fellow ‘bolter can chime in to verify.
