@Xulfiqar @SER_GTR Kinda Funny what happend.
I have changed my gear oil to Zic FF GL 4 75 85w one. Gear started to give more noise in all gears (It was noisy before but bearable). Added liqui moly MOS 2. That did not help but gear were a bit smooth at first but than you could feel some resistanc to get into gear. This made no difference to noise though.
Change gear to a used one again to flush it we used normal gear oil that was a bit thick there was very less noise in gear than we again replaced oil and mechanic this time recomended only toyota oil so that was replaced and again all gear started to whine haha. Dont know what next to try.
I also found out this is C52 but I was using C51 before and I am on high RPM in 5th gear around 700 RPM more than with C51 I wonder how much this will effect fuel economy.

C51

Gear ratios for this transmission.

Adding STP to gear is recomended to reduce some noise?
I am also not entierly happy with AISIN Pressure Plate and clutch set. Reputed shop claims its original japanese but I felt its kinda Chinese quality item.
