Hi!
Yes, I have a "notchy" box. Yes reading forums etc... there are many views. Im guessing mine is the syncros. Has it got worse? No, its still the same with 25kmiles later. I bought my car with 36K miles or so. I didn't notice it when I test drove it. I did notice one morning doing the school run. When transmission oil is cold it seems to happen or more prone to happen. However, if you were to floor it, all gears work in harmony. Silky smooth. I love the manual box.
My 2nd and 3rd are like this. More so 2nd. I have found when changing down into these gears I blip the throttle and it helps. That is, I do not get any notchiness. I changed my gearshift to the Short Shift Kit and had it fitted by OPC. I think it actually improved it a little. I would say, that its normally changing down I have found it. But it can happen changing up, especially when cold. Unless you floor it like I said earlier...which you wouldn't want to do when the car is cold anyway.
A few occasions I have experience not being able to get into 1st gear when to take off at lights etc.. I find I have to go to 2nd and then 1st. Again, this to me is not the transmission oil. Am I concerned? No. Im used to it and it doesn't happen anymore because of how I drive it.
I've read threads about new cars having this and others never having this.
I think at some stage I will have the 1st, 2nd and 3rd syncros replaced but for now, the car is perfect.
