Hyundai i30 hard to engage 1st and reverse gear. Issues and fixes.

In this video I describe two possible causes for i30 difficulties to engage first and reverse gear. Unfortunately the damper valve issue is detailed here superficially, but you can find more detailed videos of it from youtube. Couldn't find videos from master cylinder, so I decided to make one. Master cylinder part number: Sachs 6284600872. It is OE quality part.
