Castrol Transmax Transaxle 75W-90 is my recommendation
Pros: my recommendation
Vehicle:
Volkswagen Jetta
Yes i used castrols uk synthetic smx-s 75w-90, i tried this because it said on the castrol site is used as a problem curer by many manufacturers. Also i know from experience that synthetics help to cure notchy gears when cold, which it did the change felt brillant but i started getting random crunching in 2nd when hot and changing from high rpms. So i reverted back to castrol ep80 and crunching stopped but my 2nd is notchy when cold
Pros: change felt brillant
Cons: crunching in 2nd when hot
