Fixing the Shifting Issues

[Vitalie]

I went to a shop and they had the right size tool. took both plugs out and changed the oil to Red Line MT-90.

I also checked the cable adjustment while the car was up and it felt looser than I did it just last night.
So the question is when cold is it tighter or it just got loose a bit?

Other than that it shits much better but to down shift in 3 I have to let it slow down to at least 15mph or to rev the engine just a bit not to grind. Syncros
I believe this the most can be done other than rebuilding the transmission or getting another one.

Thanks for the big support here.
