Technician A says anti-foam additives help to prevent foaming of the transmission fluid. Technician B says viscosity modifiers cause the transmission fluid to be thick when cold and thin when hot. Who is correct?

D) Neither A nor B

Question

Quizplus · Accepted Answer

Anti-foam additives are indeed used to prevent foaming in transmission fluid, which can cause issues with lubrication and fluid dynamics. Technician B is incorrect because viscosity modifiers are designed to maintain a more consistent viscosity across temperature changes, not to make the fluid thick when cold and thin when hot.
