Final answer:
True, automatic transmission fluid should be changed if it smells burnt. It indicates the fluid is breaking down and may also signal bigger transmission issues.
Step-by-step explanation:
Regarding the question of whether automatic transmission fluid should be changed if it smells burnt, the answer is A) True. If the transmission fluid has a burnt odor, it is indicative of overheating and potential damage to the transmission system. Over time, transmission fluid breaks down and loses its ability to properly lubricate and cool the transmission, leading to increased friction and heat. This condition not only degrades the fluid's protective qualities but could be a sign of more serious issues within the transmission system. It is crucial to address these problems promptly by having the fluid changed to prevent further damage, which can be costly to repair.
