Gear shifting problems when cold

[Peteridd117]

I’ve got a Audi s1 it’s got an uprated clutch. When starting car and setting off into first it won’t go straight away into gear you have to fight it or put it back into neutral then into first takes a couple tries. Normally only first gear and sometimes second, But once cars been running approx 5mins and is warming up it’s fine goes into all gears no problem. Any ideas what this could be, clutch? Transmission fluid? The clutch was already installed when I bought it aswell

Very good stuff indeed.

One potential cause of that in a conventional manual 'box is that when cold, the oil is so viscous that the synchro hubs can't overcome the internal drag.

Using multigrade oil as recommended below would be a good fix for that (I have no idea whether that specific oil is suitable).
