Didn't even think about doing what you said it never crossed my mind. It went into gear doing that.Still possibly a weak master cylinder.
This is a two person job.
Just to prove it is only hydraulics, (master or slave, with an external slave cylinder) it is sometimes possible to push the clutch arm out as far as possible at the bell housing by using the hydraulics, then use a bar or tyre lever to move it the rest of the way. if it can be safely held in that position then start engine and see if it engages all gears correctly, if so then at least you know it is external.
Though make sure you do it safely![]()
Even tried bleeding with someone holding clutch down when I pressure bled it.
Also compressed the slave while bleeding.
Just annoyed it's got worse with a brand new parts lol
