I’ll try and see it could be the release bearing. As for the 4th gear grind maybe clutch doesn’t disengage properly cause it is slightly like very slightly hard to go into first could be due to the slab cylinder pin being short uni clutch is a twin plate. Ive attached some assembly photos hopefully you can open the link and see maybe detect what’s wrong https://share.icloud.com/photos/0dc2YvW__Hl6jl-l2_0jejjpg https://share.icloud.com/photos/09e0jkWOK-vP48c1cfY6u3ViA https://share.icloud.com/photos/0b4rDmh5R7pK7fb1VtND73a3g https://share.icloud.com/photos/05eeUi_6dC4DVi80jOUYDgb0g https://share.icloud.com/photos/06335TgY1XxyIJal_wkdQLhzw

Just the down shift from 5th to 4th is crunching

I was told to put in vmx80 for about 500kms. Then change to Motul 75w90 it goes into all gears smoothly, I do hear a slight hissing noise when release clutch

Did you manage to fix the problem? I’m having the same issue but everything is new in my gearbox

Was looking for some help Recently got the speedtek gearset installed all gears work fine goes in and out of gears smoothly, only issue is that it crunches from the downshift from 5th to 4th. Also had new uni clutch installed aswell track edition any help will be appreciated
