Best Gear oil for Volkswagen Golf

I will add this, I drove it for 10-15 miles already, and where as the transmission had a bit of a whine at 65 before, now it is really quiet. And it may be placebo effect, but it does feel like it goes into gear smoother than before.

I changed the fluid because I wanted to be running a superior fluid compared to what was put in from the factory. That being said when I drained the factory gear oil with under 2k on the odo it already smelled burnt but obviously there was no color change since it was hardly used but just based on the smell of the gear oil you can often tell how hard it is being worked and how well it is holding up to the stress inside the diff itself.

Why I am writing a review about this gear oil, because since I owned this car shifting into second gear on cold morning has been a little bit hard. And last week when I went to my mechanic for an oil change as usual he used full synt Motul oil 5w40 and he suggest me to use motylgear 75w90 gear oil. REVIEW... Before: when it's below 10C outside or on the morning for the first 5 or 10 minutes it's hard to shift in second gear. Most of the time I try to rev match or shift in third skipping second gear. Even after 10 minutes sometime I get a nice grind in second gear. Now: Yesterday it was about 2C in the morning and the improvement is about 60% better and only after 2 minutes it was shifting like butter. Everything seems to be a lot more smoother and safer. I don't feel like I am going to break something when I shift in second gear, to be honest I am very surprised and happy.

this morning i change the gear oil to MT90 redline still no luck the 1st gear crunch noise still there
