3rd gear crunches when down shifting

Need some help as to what this could be and what I'll need to do to fix it. Cheers

The cheaper option if you don't want to spend $$$ now is the double clutch, rev match thing. I taught myself how to. It just becomes 2nd nature after a little while. Also I found having gear oil changed to MT90 helped too.

do the simple stuff first before you even think about a gebox rebuild- check all the bearings etc at each end of the shifter cables (deltav do a kit), there are lots of posts on this topic if you search the forums. tired engine/gearbox mounts can also attribute to shifting issues

Edit. The resistance dissappears as the car gets warm and then it starts to shift smoothly could this be cluch related

Cheers. Also the cluch pedal is very stiff could that indicate anything aswell

It's really firm

Having too firm a clutch can be a sign of a faulty slave/master so don't assume it's all perfect. Like the others have said, give the clutch a bleed. It's a difficult job but I have a write up in the how-to section that seems to work for me. 
 
Also change the gearbox fluid, MT-90 is used by most of the members here and is a GL4 oil. Always undo the fill bolt on the box before draining the fluid to make sure it's not seized and you'll be sweet.
