i have heard people using gear oil 75w-90 in manual gearbox of toyota 1.6 facing problems with noises. A dealer of toyota recommended
ATF OIL to be used there. Is that right?
I know that atf oils have lower viscosity compared with 75w-90. Is tha possible atf to cause problems if used?
What are other recommended products tha can be used in toyota manual gearbox to avoid the problem?
thanks a lot
