i have a manual td42 gq and 1st 2nd and 3rd crunches when i shift, it only happens when the syncros wouldnt line up if that makes sense, like the clutch wont fully disengage. tried a new slave sylinder and bled it multiple times with no effect, also tried adjusting pedal so its now maxxed out... is there anything else i can try before i take the box out and replace fork and pivot ball etc? any help appreciated. thanks
